Galgus raises 2.5 million euros to finance its growth and boost its international expansion

Galgus, the startup which specializes in research and development of wireless network technologies, has completed a round of investment led by GED Capital (through its Conexo Ventures fund) and Mundi Ventures, with the additional participation of GoHub Ventures, Global Omnium’s corporate venturing arm, and Wayra, Telefónica’s open innovation hub. With over seven years of corporate history, Galgus deep-tech aims to improve the user experience of a WiFi network.

Galgus has developed an innovative technology, Cognitive Hotspot™ Technology (CHT), which is capable of improving WiFi networks by providing intelligence to their different access points. Thanks to CHT these access points acquire the capacity to measure what is happening around them, share information, and thus optimize resources in real-time, improving performance by 400%.

With Galgus’s solution, network owners enjoy WiFis that are more reliable, greener, and of a better quality of service for their users and connected devices. At the same time, they also have many features that increase the value of their networks such as tracking devices, heat mapping generation, hacker detection, or cloud management, among others.

Galgus has been considered as the best digital infrastructure startup by EIT Digital in 2016 and recognized in 2018 by the European Commission as a company with high potential in its sector through the award of a ‘Phase II SME Instrument’ in 2018.

Its technology can be found in many different contexts. Besides passenger transport such as air, rail, sea, or bus, it is also deployed, to mention a few examples, in hotels of the Barceló chain or even in the Benito Villamarín stadium of the Real Betis football club, wherein 2019 it offered WiFi service to all the accredited press during the final of the King’s Cup between Valencia CF and FC Barcelona.

Moreover, it is worth mentioning the work it has been developing with Telefónica, its partner, in the rollout of WiFi4EU projects. This is a European Union initiative aimed at reducing the digital gap by helping to overcome connectivity problems in Spanish rural areas, where it provides service to some 250.000 people so far.

With the investments from GED Capital, Mundi Ventures, GoHub Ventures, and Wayra -Telefónica’s open innovation hub-, Galgus has raised the funds and assistance required to finance its growth and boost its international expansion.

According to its CEO and Co-Founder, Jose Gonzalez: “thanks to the great work developed by the Galgus team during all these years, we have achieved a very advanced and technologically disruptive system that has been validated by the market. Now, with the capital provided by our investors, we will be able to take on new opportunities, scale up the business and grow this project that we started around seven years ago”.

Telefonica and Galgus connect the ‘Empty Spain’

Telefonica Entreprises and Galgus, a company specialized in research and development of wireless network technologies, have reached an agreement to connect more than 250,000 people in thirty towns all around Spain through free WiFi networks.

This initiative is part of the fourth call of the WiFi4EU program of the European Commission, whose objective is to reduce the digital divide in those municipalities that are further away from urban centers and, therefore, may have worse connectivity.

Agustín Cárdenas, Director of Digital Transformation of Telefónica Enterprises pointed out that: “The COVID-19 pandemic has caused that some people are migrating from big cities to smaller towns. Once there they need to still experience a high-quality connection when using their smart devices. Thanks to the deployments that we are doing with Galgus, municipalities are able to enjoy new WiFi networks, or improve existing ones, offering residents and visitors high-quality Internet access through free WiFi access points located in public spaces, such as parks, squares, libraries, or health centers ”.

Telefónica and Galgus are also offering these towns with a wide catalog of WiFi access points in which Cognitive HotspotTM Technology (CHT) makes them intelligent by providing them with features capable to optimize, manage and analyze any network from the cloud.

“In seven years since we founded Galgus, we have worked to consolidate a great human team and to develop a technology capable of improving the user experience when using WiFi networks. Furthermore, our solution makes it easier for the network owner to obtain much more value from their deployments while choosing the hardware that best suits their needs”, said Jose Gonzalez, CEO, and co-founder of Galgus.

Cognitive HotspotTM Technology is a patented, multi-platform, and hardware-agnostic software that automatically optimizes radio resources and enables the network owner to enjoy advanced services such as device location, heat map generation, hacker detection, and secure cloud management. All this helps to improve network performance by 400% while reducing interference levels and power consumption.

Galgus CHT technology is currently used by more than 600,000 users worldwide on a daily basis in companies, educational centers or sports venues, hotels, and luxury resorts, as well as in passenger means of transportation (by land, sea, and air).

Galgus, new member of the WiFi Alliance

WiFi is the main option to connect to the Internet. Thus, more than half of the Internet traffic is done using this wireless connection technology. A technology that, in these times of pandemic and a new normal, is playing a fundamental role, offering users the possibility of working, studying, and enjoying themselves remotely.

Since last July 1, Galgus is a member of the main international organization for WiFi technology, being one of the few Spanish companies that have achieved it to date.

The WiFi Alliance (www.wi-fi.org) is responsible for leading, developing, and adopting the standards agreed by the WiFi industry. To do this, it fosters collaboration between member companies, thus promoting innovation in this field.

WiFi Alliance importance is appreciable when reviewing its list of member companies. Thus, global giants such as Apple, Intel, Microsoft, Facebook, Nokia, or Samsung; telecommunications operators such as Telefónica, Deutsche Telekom, Vodafone, or Orange or manufacturers such as Acer, Logitec or Motorola, are part of this organization.

Galgus CEO and Co-Founder, Jose González, points out that “for our company, having been admitted as members of the WiFi Alliance is a recognition of the development in WiFi technology that we have been making for more than six years. This achievement is comparable to the patents that our products have obtained in the US and Europe”, adding: “This is something that gives not just added value for our brand but also for our clients and society”.

WiFi Technology to Control Capacity in Urban Buses, Subways and Trains during COVID-19

Galgus technology, patented in the US and Europe, and used daily by more than a million people worldwide can help public transport operators to control capacity in buses, subways, and trains while achieving a better experience for passengers by providing them with WiFi connectivity for their smart devices.

The New Normal era, and the necessity to comply with Social Distancing rules, will be hard to meet by means of transportation in which there’s not any assigned seat for travelers at all. Thus, control of capacity becomes a critical factor to avoid outbreaks of the COVID-19 pandemic.

Urban buses, trams, subways, and commuter trains are means of transportation where an assigned seat is not offered, even in some of them it is common to see passengers traveling standing.

Galgus’ WiFi technology, already present in bus lines and trains, represents a unique solution, not just for its ability to offer the capacity level in real-time, but for its ability to improve the user experience for travelers by offering them a good Internet service.

Location feature as a key solution.

In every means of transportation in which Galgus’ WiFi technology is deployed, the “Location Analytics” feature collects anonymous information from smart devices on-board, whether they are connected or not to the network.

It is the only solution in the market -patented- capable of locating and -as indicated- counting devices that are connected or not to a WiFi network. That’s key to obtain reliable analytics that responds to the situation in real-time.

User´s privacy is guaranteed as data remains anonymous. Also, it is not necessary to install any mobile apps that will take up space on their devices, neither be connected to the network.

Cloud management as a tool for decision making.

For those responsible for these passenger transportation operators, it means the possibility of accessing a cloud management center, accessible from any location, and with the possibility of being integrated into other applications that might be already being used by the operators.

With this tool, they will be able to locate and count devices that are present in that network. Also, they will be able to visualize them through heatmaps that indicate the density of people in real-time and they will be able to program alerts when a certain occupancy limit is reached.

A long-lasting, effective, and profitable investment.

The pandemic should pass away once an effective vaccine becomes available. Thus, many of the investments made to assure security for passengers will become obsolete. That’s not the case with Galgus technology; therein lies one of the virtues that makes it unique: its usefulness goes far beyond this situation.

Travelers will continuously need to connect their devices to the Internet and transport operators will have a system that they can either monetize or offer as an added value item that improves the user experience for travelers.

Advanced WiFi Technology that guarantees security at beaches this summer

Galgus technology, patented in the US and Europe and used daily by more than one million people worldwide can help coastal municipalities to control crowds at beaches while achieving a better experience for visitors, providing a WiFi connectivity for them to connect their smart devices in these spaces.

With the upcoming summer season, there are still many uncertainties about what it is planned for the Touristic Sector. One of them refers to the possible crowds that may occur at beaches. Proper control is required to avoid COVID-19 outbreaks while being aware that most of them will come from visitors from other places.

Saying this, Galgus WiFi Technology revolts as a unique solution, not only for its ability to provide a real-time beach occupancy but for its ability to improve user experience, guaranteeing a quality Internet service for visitors who come this summer to coastal towns.

Location Analytics as a Key Factor

Galgus feature “Location and Analytics” can collect anonymous information about users who are in determined areas, whether they are connected or unconnected to the network. Moreover, it can be deployed in beaches, ships, downtowns, fairgrounds, recreational spaces, and in any area where WiFi networks can be installed.

It is the only solution in the market -patented-, capable of locating and, as mentioned, of counting devices that are not connected to a WiFi network, a key detail to obtain reliable analytics that respond to the live situation in real-time.

User´s privacy is guaranteed as data remains anonymous. Also, it is not necessary to install any mobile apps that will take up space on your devices neither be connected to the network.

Cloud as a tool for decision-making

Galgus WiFi Technology, that can be immediately installed in all these mentioned locations, has already been deployed in similar environments, as it is the case, among others, of the Hotel Barceló Sancti-Petri (Cádiz, South of Spain) where its guests enjoy everyday quality WiFi connectivity, even at the beach.

For coastal municipalities, it means the possibility of accessing a control center in the cloud, accessible from any location, and that can be integrated into any other application that is being used by the network owner, such as the ones for traffic controls, or security cameras.

With this tool (cloud), network owners will be able to locate devices that are present in that network (connected or non-connected). Also, they will be able to see users through heat maps that indicate the density of people in real-time, to set alerts when a given parameter is reached or delimit limited areas (Geofencing), as well as knowing the traceability, that is, where these people have passed and with whom they have come across.

A long-lasting, effective, and profitable investment

The pandemic will pass and many of the investments that are now going to be made will become obsolete. This is not the case with Galgus technology; therein lies one of the virtues that makes it unique: its usefulness goes far beyond the lasting of this situation.

People will continuously need to connect their devices to the Internet, and municipalities will have a system they can either monetize, offer as an added value, or use as a means to improve their tourism promotion campaigns beyond summer months.

Discovering and peering WiFi devices in 802.11s mesh networks

Mesh networks are an efficient way to connect WiFi devices without using Ethernet cabling to connect to the backbone. It consists of WiFi devices that have one or more radios, with the particularity that they are all considered STAs (clients) and none of them is considered an AP in the network architecture. Neighboring radios are discovered using beacons and may or may not be paired to create a communications channel based on various criteria that are left to the discretion of the administrator.

However, the configuration is not clear in most scenarios.

That is why in this article we characterize the discovery and peering of devices based on mesh networks based on 802.11s.

1. Radio stations evaluate RSSI_threshold when they discover a nearby radio candidate to peer with them:

a) If that candidate radio has more signal than the threshold, the link is established (mesh plink will remain: ESTAB and mesh PS mode will remain: ACTIVE in iw dev wlan0 station dump).

b) If that candidate radio has less signal than the threshold, the link is not established (mesh plink will remain: LISTEN and mesh PS mode will remain: UNKNOWN in iw dev w wlan0 station dump).

In both cases, in the web they shall appear in the list of connected stations, but in case b) the Throughput will be 0 and the Bandwidth will be 0 as well.

2. Once they have discovered the nearby radios and the peering has been determined, it doesn’t matter if it goes above or below the threshold. In other words, moving the AP closer or further away does not change from ESTABLISHED to LISTEN or vice versa. In order for the candidates to be re-evaluated, the radio or AP must be restarted (by doing wifi). A connection established before setting the threshold will still be established.

3. Even if you change the threshold during runtime (with iw dev wlan0 set mesh_param mesh_rssi_threshold), if the radio or AP is not restarted (by doing wifi), the condition will not be re-evaluated. An established connection that deteriorates after setting the threshold will not be blocked.

4. RSSI_threshold can be set on the web (negative value) or in /etc/config/wireless. And then restart the radio or AP. Therefore, the iw-full tool is not needed.

5. If you want to block a particular radio candidate, you can use plink_action against the MAC of that radio. The mesh plink will remain: BLOCKED in iw dev wlan0 station dump.

6. If you want to limit the number of radio peers that link to your radio, you can use mesh_max_peer_links, knowing that you will accept the first ones you find (watch out, as they are not necessarily the best ones) until you reach the set number. The mesh plink will remain: BLOCKED in iw dev wlan0 station dump.

We hope this clarification will be helpful to all network engineers and technicians who want to configure and operate mesh networks based on 802.11s.

Galgus and Telefonica strategic alliance

.- Telefonica incorporates Galgus’ CHT (Cognitive Hotspot Technology), a multiplatform and hardware-agnostic software that provides intelligence to companies WiFi networks.

.- Telefonica strengthens LAN/WiFi solutions in Spain with more than 4,000 businesses where they manage more than 120,000 WiFi access points with a comprehensive care service model.

Madrid, 19 November 2019.- Galgus, a Spanish-based deep-tech company specialized in the research and development of wireless network technologies, and Telefonica Empresas have reached an agreement to incorporate Galgus WIFI solutions in Telefonica’s connectivity proposal for SMEs, companies and public administrations with the objective to facilitate them the adoption of high performance and cost-optimized WiFi solutions.

Real-Time Signal Strength Heatmap

What’s the aim?

To visualize graphically interesting information of the network depending on the position of the connected devices.

What is it?

This ” Real-time Signal Strength Heatmap” feature does the following: Once the CHT system is able to locate most devices in a WiFi network, its estimated position can be matched with other interesting network metrics to build real-time heatmaps that show interesting information.

 

 

What is it for?

This allows the network administrator to display in real time the network quality metrics, such as signal quality (related to network coverage), connection mode (related to device capabilities), modulation used (related to transmission speed).

When?

This functionality is already in the product (Q9) for the KPIs connection mode, MCS and SNR. We have in roadmap, in addition, to use the data record in the Cloud Manager to be able to interpolate and to draw the heatmap in all the zones that surround to the WiFi network (not only in the points where there are connected devices).

Location, Positioning and Tracking of WiFi Devices

What’s the aim?

Locate and track WiFi devices in the vicinity of our WiFi network, without the need for costly fingerprinting campaigns of the deployment, or asking users to install annoying applications.

How does it work?

This “Location, Positioning and Tracking” feature does the following: Galgus has invented (patent pending) a technique to continuously probe most of the connected devices, without affecting the performance of the network, so that the APs in the area with CHT are able to have fresh information from them. Thanks to this information, the CHT system is able to estimate the position of the devices by trilateration and upload the data to the Cloud Manager.

The position is estimated without the need for expensive fingerprinting campaigns of the site, and without the user having to install annoying applications or modify their terminal.

 

 

Why WiFi-based location?

Our algorithms are based on state of the art and have yielded good KPIs both in laboratory environments and also in actual deployments. In addition, our localization method is protected by 3 patents (patent pending), which shows how innovative the system is.

It is true that WiFi technology has physical limitations when it comes to giving a accurate location, but its deployment and operation is much more affordable than with other technologies. In our opinion, this is a fundamental advantage over less pervasive (or more invasive) technologies such as LiFi, Zigbee or video cameras. In addition, the IEEE itself has noticed the potential of location systems based on 802.11 and is proposing new standard amendments (802.11mc, present in Android 9 devices) to improve the resolution, so thanks to the Galgus’ Software-Defined WiFi approach, these improvements can be incorporated into the already deployed network in a future update.

Is it an experiment, or has it already been deployed in the real world?

Galgus R&D team has focused on making a technology exclusively based on WiFi and from the network side, that is: the user should not be disturbed with annoying applications, nor to modify the firmware of your device. At the end of 2019, we have our location system based exclusively on WiFi for connected devices in different sites (hotels, offices, convention centers, football stadiums, universities, or onboard trains), even if they falsify the MAC address identifier.

Will it affect the performance of the WiFi network?

No. Moreover, we can count and locate the devices while providing a top quality wireless Internet service, as the system takes advantage of the small silences between packages to poll the devices and perform position estimation. This trilateration is done in the APs themselves, without the need to perform the calculation in the cloud, which is aligned with the data protection law. Of course, the data can be queried in real time from the Cloud Manager. This technology is backed by two new patents (patent pending).

What is it used for?

Thanks to the location and tracking, the owner of the network can have a physical map in real time of most of the devices that are connected to WiFi, along with their network metrics (real MAC addresses, IP address, uplink and downlink data rates, signal quality, mode, spatial streams, MCS, SNR, number of packets, etc).

When?

This functionality, for connected devices, is already in the product (Q9). We are able to locate most devices connected to the network, even if they fake their MAC address in the Probe Requests. We have in roadmap, in addition, to do the same with non-connected devices (for non-connected devices with real MAC is already implemented in CHT in the product and is being tested, while for non-connected devices with fake MAC will be throughout 2020). This is also aligned with the data protection law. To our knowledge, we are the only ones who are able to count and locate non-connected devices even if their MAC address is randomized.

Runners-up of the WiFi-Now Awards 2019!

Galgus was declared as Runners-Up of the WiFi-Now 2019 Awards at the ceremony that took place yesterday at the WiFi World Congress International Expo & Conference celebrated at the ILEC Conference Center in London.

Among the eight possible categories which are: “Best Service Provider WiFi Solution”, “Best Enterprise WiFi Solution”, “Best WiFi IoT Product”, “Best In-home WiFi Product”, “Best WiFi Service Provider”, “Best WiFi Startup”, “Best WiFi Innovation” and “WiFi NOW Affordable Connectivity Award”, Galgus has been declared Runners-Up for the “Best Service Provider WiFi Solution” category.

Galgus’ candidacy was based on the world’s first Software-Defined WiFi for wireless networks, that the Spanish company has been working on for several months. The Software-Defined WiFi paradigm proposes the independence of the software from the hardware, allowing the network owner to choose the Access Points (APs) that best fit his needs and budget, and then install Cognitive HotspotTM Technology (CHT) to unleash all the potential. Thanks to this, a commodity AP becomes an enterprise-grade AP with a simple software update of less than 1 minute.

Galgus’ CEO, Jose Gonzalez, at the end of the ceremony pointed-out: “Firstly I would like to congratulate winners Qubercomm, they are doing great!, for us being shortlisted was a prize itself, competition was very hard and a lot of big names of the industry didn’t arrive so far!, so we are happy enough… but we’ll try again soon!

Unveiling of randomized MAC addresses of WiFi devices

What is the problem?

When a device is connected to an AP, it only communicates with that AP and on that channel. This is inherent to any WiFi network.

From then on, the rest of the nearby APs will only know about that device because they hear (very occasionally) some loose frames coming from that device. These frames usually exhibit a random (false) MAC address, and therefore nearby APs will not be able to identify who it actually comes from. This is how the WiFi standard works from the beginning, and this brings numerous problems derived from the fact that neighboring APs do not have updated information from nearby devices.

How does it work?

This “Unveiling of Randomized MAC Addresses” functionality does the following: Galgus has developed (patent pending) a technique to constantly stimulate a device in order to reveal its real MAC address to nearby APs with CHT, with independence of the operating channel, while still servicing other connected devices. It doesn’t work with all devices, but it does work with most modern smartphones, tablets and laptops.

What is it for?

This greatly improves the CHT location, smart roaming and load balancing systems, as neighboring APs with CHT always have fresh and reliable information about nearby devices, allowing them to make better decisions.

When?

This functionality, for connected devices, is already in all Galgus APs. We have in roadmap, in addition, to do the same with non-connected devices (2020).

#OnTour: IOT Solutions World Congress 2019

The IoT Solutions World Congress is the largest IoT event in the world to get inspired with new ideas, solutions and people. A unique event dedicated exclusively to joining IoT providers with industry in order to help the latter increase productivity via this disruptive technology. Since it’s first edition back in 2015, the event has grown to become the global reference for industrial IoT, and the annual meeting for industry stakeholders to establish new partnerships.

+300 companies from around the world exhibit across 32,000 square meters at Fira de Barcelona. One of them, Advantech, is a global leader in the fields of IoT intelligent systems and embedded platforms. To embrace the trends of IoT, big data, and artificial intelligence, Advantech promotes IoT hardware and software solutions with the Edge Intelligence WISE-PaaS core to assist business partners and clients in connecting their industrial chains. Advantech is also working with business partners to co-create business ecosystems that accelerate the goal of industrial intelligence.

One of this partners is Galgus, and that’s the main reason to be there with our  EMEA Sales Director, Francisco Campins. During the event, Galgus is having the opportunity to hold several meetings with representatives from companies from all around the world, and it seems that our Software-Defined WiFi technology is awakening interest from our visitors.

Importance of load balancing in high-density WiFi

 

WiFi is the iconic technology of our time. It may seem cumbersome, but it’s difficult to think of another technology with greater penetration into society. Who hasn’t seen someone walk into a cafeteria and ask the WiFi key? Who hasn’t seen reviews of a hotel complaining about the quality of the wireless connection? Moreover: it is already found in the dictionaries of half the world included as a colloquial term.

However, the 802.11 standard has been with us for two decades and, although it has evolved to adapt to the new times, we must bear in mind that it was designed for a world that is not the world of today. The standard on which WiFi technology is based was conceived to replace wired networks at the end of the last century, which is why it does not take into account the vicissitudes of the average user of today. Fortunately the standard, very cleverly, leaves many network decisions unspecified that we can use to get the most out of our WiFi infrastructure.

Thanks to this, innovation companies such as Galgus can develop algorithms that automatically optimize the network in terms of the use of radio resources (power, bandwidths, channels, use of antennas, etc.) and logical (user association, traffic limits, roaming, etc.).

Specifically, in a WiFi network with several APs and several radios available, the effective distribution of users according to the load of resources is essential. It is okay to control the user association to ensure that resources are allocated in a sustainable way (what Galgus calls Prebalancing), but we must be aware that an AP or a radio with few very demanding users (videostreaming, downloading files, etc.) will suffer much more than another with more users less demanding (email, chat, etc.).

That is why all Galgus products include, at the heart of their embedded software, an adaptive Load Balancing (LB) algorithm that moves users between available APs and radios in real-time, depending on their load. Besides, it does it anticipating the impact that this transition is going to have on the APs and target radios since it would not make sense to make a movement that would worsen the network.

To do this, Galgus APs monitor both their congestion indicators and those of their neighboring APs, without the need for a central controller or a cloud decision-making system. What’s more, they don’t even require Internet access for the network to be dynamically optimized. Galgus intelligent APs are aware of the transition possibilities of their clients, and that is why when they consider that moving a device to other resources is going to have a positive impact on the network, they do not hesitate to do so.

Of course, all this must be done in a good signal quality situation (several APs available to serve the devices). If signal quality degrades for some users, other network optimization algorithms such as Smart Roaming (SR) or Automatic Power Control (APC) would come into play. At the end of the day, an intelligent network should not neglect any user, as we also know that the weakest user can have a very negative impact on the network if it is not given a solution in time. But that would be material for another day.

#OnTour: EIT Rail Industry event

Organized by the European Institute of Innovation & Technology (EIT), the event was an  innovation workshop with a strong emphasis on corporate tech needs, market validated solutions, and B2B matchmaking in the Rail Industry, Multimodal Transport and the Hubs of the future.

The event represented an opportunity to gather with rail component manufacturers, rail network operators, infrastructure providers, cargo shippers, transport hub operators and municipal planners, supervisors… all them in the ready to met digital solution providers arriving from European destinations such as Galgus.

According to Galgus’ EMEA Sales Director, Francisco Campins, “to pitch and met with representatives of companies such as the Hungarian National Railways, SNCF, or the UNIFE among others, has been an excellent opportunity for us to showcase the benefits of our Software-Defined WiFi technology”.

#OnTour: South Summit 2019

Since 2012, South Summit is the Leading Innovation Global Platform focused on business opportunities and disruptive trends, that gathers together the entrepreneurial ecosystem with top innovators from Southern Europe and Latin America. Galgus had the opportunity to pitch there at the 2019 edition.

Galgus was one of the 30 tech companies presented by the Andalusian Government at the “South Summit 2019”. Among them, our company was one of the only five designed to pitch in front of the audience gathered there.

Galgus’ CEO, Jose Gonzalez, pitched about the deep-tech company and the benefits of its technology based on the Software-Defined WiFi. In addition, he reviewed all the vertical markets in which the Seville-based company is present such as aviation, rail, maritime transport, buses, hotels, convention centers, soccer stadiums … he could explain as well all the advanced features that +650,000 users worldwide every day are enjoying when they connect their devices to the internet.

According to Gonzalez, “We really appreciated being invited by the Andalusian Government. It’s a kind of recognition towards what we are developing. Such an event with such an interesting audience is very important for a company such as Galgus”. Adding “The air was full of great ideas around! So inspiring!”.

#OnTour: WBA Conference 2019

For the first time ever, Galgus exhibited at one of the main events of the WiFi industry. The Wireless Global Congress organized by the Wireless Broadband Alliance (WBA) was held at the Westin Grand Frankfurt in Germany on September the 29th and October the 1st. Galgus booth hosted numerous meetings with professionals from the industry and its CEO, Jose Gonzalez, had the opportunity to address a presentation about Galgus’ disruptive Software-Defined WiFi technology.

The event gathered WBA members and industry partners for one of the world’s leading WiFi events. The topics of the Wireless Global Congress included: enterprise wireless, WiFi evolution and monetization, In-Flight WiFi, WiFi 6 for enterprise verticals, In-Home Wi-Fi experience and IoT and connected vehicles.

During two days of event, Galgus held about 40 business meetings at its booth with companies and professionals from more than 15 countries. There, Galgus was able not just to explain its technology, but to address a presentation about Galgus’ Software-Defined WiFi in front of an audience of around one hundred experts and decision makers of the WiFi industry. The Software-Defined WiFi paradigm proposes the independence of the software from the hardware, allowing the network owner to choose the Access Points (APs) that best fit his needs and budget, and then install Cognitive HotspotTM Technology (CHT) to unleash all the potential. Thanks to this, a commodity AP becomes an enterprise-grade AP with a simple software update of less than 1 minute. To highlight Gonzalez’ presentation, he remarked: “we believe in the Software-Defined WIFi as the future for the enterprise wireless networks, where a high level of simplicity and cost-effectiveness are needed today”.

Besides that, Galgus was shortlisted for the Wireless Broadband Alliance 2019 Awards at the “Best Enterprise WiFi Network Award” category. Finally, the award was granted to Panasonic, but, for Galgus, being shortlisted was an award itself just by feeling so close to the big names of the WiFi industry shortlisted for the different categories awarded.

#OnTour: Digital Excellence Forum 2019

The event was held in Helsinki (Finland) on September 19th to 20th and Galgus was represented with our Innovation Manager, Dr. Pablo Aguilera PhD. There, he had the opportunity to meet people from several countries and discuss about the possibility of partnership agreements to participate in different projects.

The Digital Excellence Forum, also known as ICT Proposes’ Day is considered the biggest event organized by the European Commission to promote R&D in the field of information technology and telecommunications (ICT).

This research and innovation event was focused on the priorities of the European Union for the digital transformation of the industry and society. It was an opportunity for people involved in this transformation to share their experience and vision of Europe in the digital age. The event served as a platform for the presentation and launch of the Horizon 2020 Work Program.

The ICT 2019 had three main pillars:

  1. Information sessions designed to present the main features of the Horizon 2020 call.
  2. Visits to the ICT innovation ecosystem in the city of Espoo, home of VTT, the University of Aalto and the CSC Science Center.
  3. Face2Face Brokerage event, where participants had meetings with potential partners in pre-established bilateral meetings.

This last one was especially useful for Galgus, who was able to hold several interesting meetings with prominent representatives of the European innovative ecosystem.

Unlocking Benefits of Software-Defined WiFi [Whitepaper]

The Software-Defined WiFi paradigm proposes the independence of the software from the hardware, allowing the network owner to choose the Access Points (APs) that best fit his needs and budget. Thanks to this, a commodity AP becomes an enterprise-grade AP with a simple software update.

The idea is to shift the focus of WiFi networks from competition to collaboration, optimizing the use of available resources and attending the needs of all connected devices in real-time. In addition, being able to provide extremely valuable information to the network owner, as well as advanced management services. All of this without the need for central controller or cloud controller, avoiding bottlenecks, delays, and making the network much more robust and scalable.

Software-Defined WiFi brings a lot of benefits and advantages to any operator or network owner. If you want to discover them all in detail, just download a copy of our dedicated whitepaper by clicking here!

 

Galgus granted Patent in the United States!

On August 27, 2019, a patent (US 10,397,932 B2) was granted to Galgus by the United States Patent and Trademark Office (USPTO) of the United States Department of Commerce for the “System and Method for Decentralized Control of Wireless Networks”.

The invention patented relates to a decentralized control technology for wireless network installation, which distributes the control logic between all of the access points that make up the network, eliminating the centralized controller from the network architecture by means of communication between the access points themselves, thus substantially improving the efficiency of the management of the wireless network itself.

The advantages that this architecture provides are the following:

“Its been a long way to achieve this. It was back in October 2013 when we applied for this!, more than five years to, finally, succeed!” said Galgus’ CEO, Jose Gonzalez, who added “Undoubtedly, it’s not just important because it can help us to safeguard our software, the good thing is that it’s a proof of Galgus’ technological innovation capability in the wireless field”.

Galgus takes it a step further!

Research Project RTC-2017-6255-7: WiFiciency (Development of technology for cooperative, multi-platform, efficient and context-adapted WiFi networks)

The Ministry of Economy and Competitiveness of Spain has awarded in 2018 the consortium formed by Galgus and the University of Seville the WiFiciency project (RTC-2017-6255-7) within the call “Retos-Colaboración”. This is a technological innovation project between the Galgus R&D Department and the ACE-TI group of the University of Seville, which aims to develop and test new modules for CHT (Cognitive Hotspot Technology), the embedded software for Galgus WiFi networks. These new modules will explore beyond the state of the art in two main areas:

The project, entitled “Development of technology for cooperative, multi-platform, efficient and context-adapted WiFi networks” has been financed with 599.282,73 € (in the form of loan and grant) for its development over three years 2018-2019-2020.

Galgus’ first webinar ever!

Release#9 has come along with a new way to communicate with our customers and friends.

Such a wide version with so many aspects to deepen, needed a tool that allowed a more detailed explanation. For this reason, and for the first time in Galgus history, two webinars were organized (one in English and one in Spanish)

Both webinars were then uploaded to our YouTube channel and can be watched in the following links:

In the coming months we will present new add-value webinars focused in helping to optimize the WiFi networks of our customers and friends.

Stay tuned!

Making your WiFi evolve!

On July 1, Galgus launched Release#9 of its WiFi optimization software. A set of unique features, some of them never seen before, which significantly assist in improving the performance of WiFi networks.

By listening to the market, in six years since our foundation, we have learned that WiFi networks management should not be another brick in the wall of any company daily problems. Since then, our team has put its expertise to detect and build WiFi solutions aimed to deliver a great customer experience in wireless connectivity.

Over the years, continuous improvement has been present in the way this team performs and, with Release#9, we love to think that we have not improved but evolved!

In this article we will explain briefly what can be expected from the last version of our WiFi optimization software:

1.- Advanced Mesh with Self-Healing, Dynamic Re-Routing, QoS and Power Control
This powerful mesh allows deployment of complex networks where cabling is not an option, ensuring the best quality of service over the air.

2.- WPA Enterprise with Radius Support + Dynamic VLANs (802.1x)
Ensure network security and customer privacy by dynamically assigning an individual VLAN to each customer. This feature allows the accomplishment of enterprise grade projects where security and privacy is a must.

3.- Unveiling of Hidden MAC Addresses
Many modern devices falsify or randomize their MAC addresses when sending polling frames, because they are sceptical of the use of this information by network owners’. CHT reveals the real MAC address, whilst always safeguarding the privacy and anonymity of the users, and uses it to improve the quality of service in the WiFi network.

4.- Location of Connected Clients with Real or Randomized MAC Addresses
Using only the WiFi network, without diminishing its performance, CHT is able to locate connected devices whether they randomize their MAC address or not. This is all achieved without the user having to install anything additional or modify their device. The network owner can access this information and compare it to quality of service metrics in our dashboard Cloud Manager.

5.- New Modular Licenses and an Auto-Download Licensing System to Easy License Upgrades to Access New Features
CHT’s new modular licenses allow the network owner to select only those features they want to enjoy on their infrastructure, obtaining an a-la-carte license exclusively for requirements. Additionally, the APs will download their new licenses if there is an update, making life easier for the WiFi network manager.

6.- Zero-Touch Provisioning
This feature allows a newly deployed AP to automatically connect to the Internet and request, validate or update its license. The network optimization parameters are automatically configured without user intervention, although the user still has access to them if they want to modify any of them in a particular situation. Just plug and play.

7.- High Density Scenarios
Dynamic probing frames management for massive user density deployments. Due to our experience gained in high user density environments such as sports stadiums or convention centers, CHT now dynamically (and in real time) adapts the number of stored polling frames of nearby devices, to minimize memory and CPU usage whilst serving all of them. Additionally, user devices are stimulated for improved location and roamings at an adaptive frequency depending on the traffic load.

8.- Discovery of IEEE 802.11 Amendments Supported by User Devices
There are an enormous variety of amendments to the 802.11 standard that mobile devices can optionally implement to improve their features, such as the well-known 802.11k, 802.11v, 802.11r, etc. These amendments help the active discovery of new networks, seamless roaming or pre-authentication of terminals, amongst many other things. In the new release of CHT, we have improved the discovery of these advanced features and they are best exploited to maximize the quality of service for each user.

9.- Support of Multi-thread Operation
The AP is able to optimize performance, locate user device and maintain user security, all at the same time, without WiFi service disruption to all users.

10.- Better… Improvements in algorithms, bug fixes, binaries, cloud-manager and much more…

The WiFiciency project closes its first year successfully!

On May 31st 2019 the first annuality of the WiFiciency project has finished. We can say that these first steps have been a success, because the milestones that were raised in the initial plan of the project have been achieved:

– We have studied the state of the art in relation to 802.11 wireless networks and the optimization of radio resources, as well as estimation, classification and prediction techniques using machine learning.

The new release of CHT (Cognitive Hotspot Technology) has been thoroughly checked, which will be installed in all Galgus laboratories for testing, as well as in the clients progressively. Hundreds of bugs have been fixed and new features have been added that were planned.

The automatic interference classification and Proactive Load Balancing (PLB) modules have been validated in proof-of-concept, so they have been moved to development and will be included in the new releases of the CHT product, expected R9.1 and R9.2.

– Construction has begun on the ETSI laboratory at the University of Seville, with 6 access points that will provide WiFi service, location and will be remotely accessible from anywhere for management.

– An article on measures of occupation of the WiFi channel using Software-Defined Radios has been sent to the URSI 2019 international congress to be held in September.

– The architecture of the Cloud Manager has been redone to improve the discovery, deployment and updating of new WiFi networks, making it easier for operators to work.

In its second year, the WiFiciency project team will continue to design and develop new modules for optimization and contextual intelligence for WiFi networks, and will test them thoroughly in the new laboratory deployed.

#OnTour: Traincomms 2019

Held in London on June 4th and 5th, the Conference gathered train operators and suppliers from all over the world. It is considered to be one of the most important annual event for wireless communications on passenger rail. Galgus was there!

As competition begins to bite in the passenger train market, on-train WiFi is an increasingly vital service, albeit one that is very hard to get right.

At BWCS’ annual WiFi on Trains Conference – Train Communications Systems 2019 focuses directly on the problems of putting WiFi onto trains, our EMEA Sales Director, Francisco Campins had the opportunity to learn and share with companies currently involved in this matters – from those trialling new trackside solutions, squeezing better connections from mobile systems, as well as those launching new innovative broadband wireless services on-board their trains as they struggle to cut costs, beat the competition and enhance the passenger experience.

Undoubtedly, this conference is a must for all those involved in on-board wireless communications.

Five benefits of a Software-Defined WiFi Network.

Software-Defined WiFi is a novel wireless networking paradigm on which advanced WiFi features are built on top of commodity off-the-shelf WiFi hardware. This approach has several advantages over traditional captive, vendor lock-in WiFi hardware manufacturer business model.

1. It disaggregates software from hardware, allowing network owners and administrators to select the hardware that best suits its needs and budget (CAPEX reduction), and then releasing its potential with software.

2.- It allows the deployment of new features at the speed of software, usually done remotely to all the sites, reducing OPEX dramatically. Just like installing a new app on your smartphone.

3.- It pursues the optimization of the WiFi network with the available radio resources, as well as the construction of new features like location, positioning and tracking, heatmap generation, detection and prevention of hacker attacks, and much more.

4.- It is applicable to vertical markets such as the aircraft or rail industry, enterprise, hospitality, convention centers, IoT, co. The same software running in different hardware.

5.- It should work even without an Internet connection and be respectful with user data protection rights. So Cloud-based features should remain only for remote management, and anonymous/aggregated data gathering/analytics. Optimization algorithms and personal information should remain on the APs/routers itself, following an edge-computing philosophy. This approach also avoids bottlenecks and delays in communication.

Definitely, the world of WiFi is going to be softwarized as it happened in other markets like smartphones (in the ‘2010s) or personal computers (in the ’90s). The main beneficiaries will be network owners, ISPs and system administrators, as well as WiFi hardware manufacturers that will improve the features and lifetime of their existing and future products.

#OnTour: all around the world!

Washington D.C., Atlanta, London, Singapore, Bangkok… next weeks are going to be quite busy for the Galgus Team as we will attend and exhibit in several congresses and trade shows. We are on the move again! Will we be able to meet you at any of these places?

Fasten your seat belts!…

By mid-May we will attend WiFi-Now USA in Washington DC. At this event we will not just meet industry leaders, entrepreneurs, innovators and experts from across the global Wi-Fi industry, but we will enjoy three days of networking and knowledge sharing.

Later, by the third week of May, we will attend one of our favorites events, The Wireless Broadband Alliance Congress in Atlanta (USA). Back in 2017, we were awarded at the “Best Industrial Wireless Service Innovation” category at their congress held in New York City.

At the beginning of June we will attend Train Communications Systems 2019 in London. Organized by BWCS, this event focuses directly on the problems of putting WiFi onto trains. There, we will be able to meet with rail operators, OEMs, system integrators, technology specialists, etc. and discuss about our solutions for the industry.

#OnTour: Orange Corporate Day 2019

A diverse group of innovators attended the event and presented disruptive digital solutions ranging from Wi-Fi optimisation to cybersecurity, robotics, wearables and smart cities. Throughout the day, there were 4 pitching sessions and over 30 parallel business meetings.

Galgus pitched its solutions for maximizing wireless performance to top Orange representatives and had the chance to deliver a detailed presentation in exploratory one-to-one meetings with Orange managers.

Speaking about the motivations behind the event Bertrand Rojat, Orange Fab’s director, stated: “Orange is very strong on its core business. However, for us to innovate faster, we need to take advantage of the strong ecosystem of startups and SMEs around us. That’s our challenge, and that’s why we’re here today.”

Christian Schneiter, Lead Product Manager for Cloud Solutions and Artificial Intelligence at Orange, addressed the success factors behind Orange’s innovation strategy: “The main factor of success is to focus on solving our customers’ problems. The technology is there only to solve real problems.” Moreover, he shared some advice for the companies in the room: “My advice is to approach us with new ideas to tackle existing problems. As a big company, we need your inputs and fresh perspective.”

Francisco Campins, Galgus’ EMEA Sales Director underlined that: “We’re very happy to be selected for this event promoted by the EIC pilot. We believe our solutions are aligned with the business of Orange and we hope to start a partnership that can help us scale-up our business and grow as a relevant player in the telecoms market.

The WiFiciency project is progressing at full speed!

The recruiting process has already been carried out by the University of Seville, and the 3 engineers have been hired. In addition, the architecture of the Cloud Manager for accessing the remote laboratory that will be installed at ETSI by summer 2019 has been reworked. The first optimization modules in which the members of the WiFiciency project will work will be:

Automatic interference classifier for WiFi (external networks) and non WiFi (Bluetooth, microwave oven, jammer, etc) signals. It is proposed to use 1D convolutional neural networks to implement a classifier.

Proactive Load Balancing (PLB) to transfer devices between radios and between APs before congestion occurs. It will use the radio channel usage metric.

Adaptive Traffic Control (A-TC) to dynamically limit network traffic if necessary, avoiding saturation. For this purpose, the reinforcement learning paradigm will be used.

These algorithms are in the design phase and if the simulations are validated, they will move on to the development phase over the next few months. We are also working on an article ( from the study of the state of the art thanks to the WiFiciency project) to be presented at the URSI 2019 congress to be held in Seville in September.

#OnTour: Rail Live! 2019.

For the first time ever, Galgus has exhibited at an event of the railway industry, Rail Live!, that had place in Bilbao on March 5th-7th. Galgus booth hosted numerous meetings with important companies and professionals from the rail market.

Rail Live! is an exhibition and conference about the impact of digital technology innovation on the rail sector. The conference brings international industry leaders to discuss how new technologies are being applied to rail to create the railway of the future. Speakers include world leading visionary CEOs. The exhibition showcased the full range of technology, hosting over 170 exhibitors in the sector from civil engineering and construction, to intelligent track innovation, IoT and asset management.

During two days of event, Galgus held about 50 business meetings at its booth with companies and professionals from more than twenty countries. There, Galgus was able not just to explain its technology, which manages to gain infrastructure cost savings up to 95% and average interference reduction up to 84%, but to demo live it!

The acceptance of the Galgus value proposition for the railway industry has been, according to Jose Gonzalez, Galgus’ CEO, “excellent, the rail segment is a market in our roadmap for 2019. Pilots carried out in the last year have offered more than satisfactory results, and it is true that attending such an appointment has been a great decision, not only in terms of new contacts made, but to make sure that Galgus solution can bring benefits to on-board connectivity as well as a raise in customer experience satisfaction rates.”

During the event, Galgus’ participants had the chance to explain its main features, being remarkable the interest aroused towards to Galgus’ Wireless Intrusion Detection System (WIDS) and Wireless Intrusion Prevention System (WIPS). Cibersecurity is seen as one of the most important problem. In fact, wireless communication has inherent vulnerabilities as the signals share the electromagnetic spectrum. For network owners and system integrators, ensuring the secrecy and privacy of communications is a major concern when operating a Wi-Fi network. Public networks with high user density, such as those present in convention centers, trains or airports, are the most vulnerable, as they are quite attractive for those who want to make malicious use of Wi-Fi. The most common attacks such as RougeAP or man-in-the-middle are very easy to carry out with free tools and are the easiest to deceive unwary users.

See you in Rail Live 2020!

#OnTour: Mobile World Congress 2019

For the third year in a row, Galgus will be exhibitor company at the Mobile World Congress in Barcelona. Considered to be the biggest and best mobile event in world, the company will introduce a brand new features of its CHT software: Wireless Intrusion Detection System (WIDS) and Wireless Intrusion Prevention System (WIPS).

From February 25th to 28th, a new edition of the Mobile World Congress will be held in Barcelona. This is an annual congress around the world of mobile communication and is considered the most important in the world of its industry. 110,000+ visitors from 200+ countries and 2,300+ companies will be there, including Galgus, which will be one of the 50 companies that will have its own booth (#44) within the Spanish Pavilion in the trade show.

There, Galgus will be able not just to explain its technology, which manages to increase the speed of a WiFi network by five times, reducing the level of radiation by 84% and reducing the electricity consumption by 60%, but to demo live its new features: Wireless Intrusion Detection System (WIDS) and Wireless Intrusion Prevention System (WIPS).

Cibersecurity is seen as one of the most important problem. In fact, wireless communication has inherent vulnerabilities as the signals share the electromagnetic spectrum. For network owners and system integrators, ensuring the secrecy and privacy of communications is a major concern when operating a Wi-Fi network. Public networks with high user density, such as those present in convention centers, trains or airports, are the most vulnerable, as they are quite attractive for those who want to make malicious use of Wi-Fi. The most common attacks such as RougeAP or man-in-the-middle are very easy to carry out with free tools, and are the easiest to deceive unwary users.

A RougeAP is a wireless access point able to fake one of the legitimate AP’s on your network. It does so by either cloning the SSID announced by your teams, the MAC address of one of them (BNSSID), or even the beacon frames and the web applications used (especially critical with captive portals). These rogue AP’s are deployed instantly by people who want to use your users’ devices to connect to them, thus allowing access to sensitive data (from user login passwords, to credit cars).

In this context, Galgus has developed and patented Cognitive Hotspot(trademarked) Technology (CHT), an embedded software that is installed within AP’s of a wide range of manufacturers. CHT has modules to optimize the network, to reduce the energy consumption or to locate devices, but also has modules to mitigate the outbreak of security problems such as rogue AP’s. All them will be showcased in Barcelona at Galgus’ booth located at Congress Square CS50. Spanish Pavilion. Booth#44.

The project WiFiciency is up and running!

The Ministry of Economy and Competitiveness of Spain has awarded in 2018 the consortium formed by Galgus and the University of Seville the WiFiciency project within the call “Retos-Colaboración”. This is a technological innovation project between the Galgus R&D Department and the ACE-TI group of the University of Seville, which aims to develop and test new modules for CHT (Cognitive Hotspot Technology), the embedded software for Galgus WiFi networks. These new modules will explore beyond the state of the art in two main areas:

– The automatic optimization of resources to improve network performance (adaptive load balancing, interference classification, congestion control, anomaly detection…).

– Building value-added functions for the network owner (device location, intrusion detection, user profiling, etc.)

To this end, three Computer or Telecommunications Engineers will be hired to become part of the team. The modules will be based on machine learning and automatic learning, in order to facilitate the deployment and operation of new WiFi networks without human interference. In addition, the improvements achieved may also be installed in networks already deployed with a simple software update. During 2019, a test laboratory will be built at ETSI facilities to test the new modules in a real working environment with real users.  This laboratory will be automated little by little and its management and monitoring can be accessed remotely thanks to our Cloud Manager.

Over the next few months we will be informing both on social networks and in this technical blog of the progress of the project. There will also be a page within the company’s website where the latest news of the WiFiciency project will be summarized.

The PTQ-15-07692 project is progressing favorably in its second year

The project PTQ-15-07692, funded by the Spanish Government’s Torres Quevedo grant, has successfully completed its second year.

In this second year, the researcher has deepened in the new 802.11ax standard, which in the coming months will lead to commercial products under the brand “WiFi 6”. So much so that as a result of this effort has been published the first book in the world entirely dedicated to the 802.11ax standard, under the title “802.11ax: The Hyperconnected World and the Next Generation WiFi”.

In addition, several SDR (Software-Defined Radios) devices have been acquired to implement re-configurable communications systems even down to the PHY layer. Small systems for simulation with real transmission and reception have been built, and in the coming months the complexity of the system will be increased in order to test new algorithms.

During the third (and last) year, the open research lines will be deepened, bringing the development closer to the real laboratory prototype.

The Virtualization of Network Functions – Reducing OPEX and CAPEX by disaggregating hardware from software

In our previous article, we introduced the problem of hardware lock-in for WiFi networks, where system integrators and network architects are demanding a more flexible paradigm for the RAN (Radio Access Network). In this regard, OPEX and CAPEX actions imply a significant cost on human resources, time, and money.

In order to address future broadband demand, the EU Commission proposes a common broadband target for 2025 of having uninterrupted 5G coverage in urban areas and all major transport. WiFi faces the same problems and challenges than 5G. However, the bottleneck of innovation is hardware-dependence of new and already deployed networks, so to be agile there is an urgent need for a paradigm shift towards a virtualization of network intelligence.

Network Function Virtualization (NFV) is the process by which software and hardware are disaggregated in network devices. With this philosophy, functions like load balancing, handovers, or radio resource management are no longer done by proprietary software which only works on specific vendor devices (known as middleboxes). Instead, new functionalities and services are delivered at the speed of software, decoupling network intelligence from the specific hardware components.

With NFV, hardware becomes a commodity. Players will be able to deploy new services and features without having to worry about the complexity of the hardware below. Although this is a software-based business, the new devices may be able to communicate with traditional, vendor-specific devices (backward compatibility).

On the quest of the virtualizing (or softwarizing) network functions, there has been a big academic effort in the last years about NFV and SDN (Software Defined Networks). However, the most advanced proposals like OpenFlow (with various controllers, e.g., Ryu, FlowVisor, OpenContrail, or Floodlight) have been designed for wired networks, and they do not provide the requested features for WiFi networks. Apart from Galgus’ software, there are not commercial WiFi multiplatform solutions planned for the next years.

In addition, most of the SDN academic efforts aims toward centralized, cloud-based solutions for the control and management of network functions. These architectures promote single-point-of-failure, critical nodes, as well as bottlenecks and delays in the decision-making. On the opposite, there is a lack of distributed, collaborative solutions with implements the NFV paradigm.

In this regard, Galgus has created CHT (Cognitive HotspotTM Technology), a patented and embedded software that unleashes the true potential of APs (Access Points) and wireless routers. CHT can be installed on multiple platforms, just like installing Android on a smartphone. For that reason, it disaggregates software from hardware and reduces OPEX and CAPEX in terms of design, automation, configuration, deployment, updating, and troubleshooting.

Do you want to test how CHT performs on your WiFi network? How about load balancing, automatic power and channel assignment, device location & tracking, remote management, smart roaming, and much more with a simple software upgrade? Just request a demo from our team, and you will be soon enjoying the most advanced multiplatform, distributed, and self-optimized WiFi software of the market.

The Edge Computing paradigm and the Internet of Things

In 2018, there are more connected devices than humans on the planet. This impressive number is near 10,000 million and keeps growing at a high rate, with more than one-third of those devices being M2M (Machine to Machine), without human interaction. In this regard, more than 3,000 million WiFi devices were sold in 2017, and the services built around wireless communications generated the 4.4 % of the global GDP (Gross Domestic Product). Furthermore, in 2020, the number of public WiFi hotspots will fold 7x, reaching more than 430 million.

This trend will grow exponentially in the next years, thanks to the irruption of IoT (Internet of Things), where connected actuators and sensors are distributed all over the cities, transports, and industries. The business around this new paradigm has reached 700,000 million € at the end of 2017, and it is estimated that there will be more than 50,000 million devices connected to the internet in 2020. Half of them will correspond to IoT, like cameras, temperature sensors, intelligent illuminations, wearables, and more.

As the reader may have noted, IoT is driving networks toward dispersion. Edge computing is a new architecture in which substantial computing (resource optimization, data analysis) is placed at the network edge, in close proximity to devices. Thus, the data is processed adjacent to the point where it was generated. Tactile internet defines networks that combine low latency with high availability, reliability, and security. Together, a network implementing both paradigms is:

In this regard, most of the commercial WiFi solutions provide a cloud or centralized controller for the APs, avoiding the edge computing approach. This implies bottlenecks, delays in the decision-making, and critical nodes. Galgus has been working in this direction during the last 4 years, developing and patenting CHT (Cognitive HotspotTM Technology). CHT is an embedded software that, when installed, unleashes the true potential of APs (Access Points) and wireless routers.

CHT galvanizes your WiFi infrastructure, measuring the environment and sharing information between neighbor APs, promoting a fair use of radio and logic resources. In addition, the network administrator may build added-value applications on top, analyzing user’s behaviors, finding patterns, and exploiting contextual information without disturbing its users.

The WiFi standard was designed years ago around the concept of competition: devices fight to gain access to the resources, operating in an uncoordinated way. Our distributed intelligence lives at the edge of the network, so it is the best way to gather fresh information from the users, doing this way before than other cloud-based or centralized services. CHT does all the processing with a focus on efficiency and robustness, promoting a cooperative WiFi world (instead of competitive).

Ok, this edge computing approach sounds promising. But … which devices does Galgus sell? CHT is a pure software solution, so it works on a wide variety of WiFi devices. Just like Android is installed on smartphones. Stay tuned to this blog in order to know more about how Galgus product disaggregates software from hardware in WiFi networks.

Modern Wireless Indoor Positioning 3/3 (Galgus’ Solution and Advantages)

Galgus is boosting wireless performance in all possible WiFi scenarios thanks to its patented Cognitive Hotspot Technology (CHT). Our Research team is focusing on developing novel indoor localisation technology, which together with the benefits of CHT will make your WiFi network perform better than ever, even in the most demanding situations.

Galgus’ Hybrid Solution to Wireless Indoor Positioning

As we have seen in previous posts, none of the aforementioned solutions shown here are free from drawbacks. For that reason, Galgus’ Research Department is focusing on developing novel hybrid solutions to the indoor location problem, which fuse several approaches in a unified algorithm.

The data fusion is done by using machine learning statistical tools, where the uncertainty in position estimation is reduced by combining guesses from different methods. Thanks to this hybrid approach, we are able to estimate the location of several users even when power-driven methods (like those based on RSSI estimation) are not accurate, like in indoor environments with multiple walls (hotels, cruises, offices, …). The location method uses advanced signal processing, geometry and statistics to reduce the estimation error.

Exclusive Advantages of Galgus’ Indoor Positioning

The main advantages of Galgus’ solution versus other commercial systems for indoor positioning are:

Applications of Wireless Indoor Positioning

Of course, after the position estimation has been done, the system administrator may use this information in many different ways. For example, we can apply statistical inference to make predictions about users’ density or roaming behaviors inside the building. We can also gather information about consumer habits and time spent on certain points of the map. In addition, it is easy to monitor the most frequented and crowded areas in an office.

This data may be used to deploy new services like restaurants or vending machines within an airport or to add contextual advertisements. Finally, we may obtain an automatic heat map of the coverage of the WiFi network itself by correlating SNIR and STA locations. This shall help network architects to detect shadow zones and to improve the dissemination of APs within an industrial facility.

Conclusions

Galgus manufactures smart WiFi solutions. We develop technology that enables performance improvement of high-density 802.11 networks, reducing the noise level in the environment, and promoting a more efficient and responsible use of resources.

With its recognised CHT (Cognitive HotspotTM Technology), Galgus provides to various vertical markets a round solution that solves the main challenges that WiFi networks are facing nowadays. Among the main benefits of our patented technology, we shall highlight that CHT increases network capacity, reduces interference, prevents congestion and slow data rates, reduces EMIs (Electro-Magnetic Interference) to critical systems, and enables automatic configuration / automatic failure detection/recovery.

Indoor positioning based on Signal Strength

Most of indoor positioning systems developed during last decade make use of the RSSI, as it is a reception parameter easily accessible from the manufacturer’s driver. This quantity measures signal power in dBm (decibels with respect to 1 mW), and goes typically from -50 dBm (near the transmitter) to -90 dBm (on the limits of the coverage area). The noise floor in a standard indoor environment is around -100 dBm. However, to estimate the distance from an analytical propagation model, we need to compute the path loss due to the separation between the transmitter (STA) and receiver (AP). Fortunately, the transmission power of management beacons (like Probe Requestsframes of STAs sounding for available APs) is usually known or may be guessed easily.

Once we have determined the propagation loss, the distance may be inferred from a logarithmic decay rule, that depends on the wavelength of the transmitted signal. There have been proposed some improvements to stabilise the distance estimation in noisy or multipath environments, but most of the indoor location algorithms solve the position by running an iterative trilateration algorithm.

However, the main problem of indoor propagation is multipath. Multipath refers to the behaviour of an electromagnetic wave reflecting and refracting on the walls, people, and objects that it finds. As a result, at the receiver antenna, one has multiple copies of the transmitted signal, with slightly different delays and attenuation. WiFi receivers are not prepared to equalise the incoming signal, so as long as this multipath is not very aggressive, it is usually assumed as a reduction on network performance which cannot be avoided.

In practice, multipath affects the SNIR at the receiver, and thus, the RSSI. This effect of random variation of the received power is also known as frequency-selective fading (or fast fading) because the channel transfer function remains no longer flat in the frequency domain. Due to this undesirable feature, real-world indoor location methods based upon signal strength attains a spatial resolution of 5-7 m, which may be negligible for some applications like robotics or logistics.

Indoor positioning based on Time of Flight

The Time of Flight of a radio signal measures the signal propagation time from transmitter to the receiver, to obtain the distance between the two devices. The electromagnetic waves propagate with the speed of light, which means that for the distance between stations to be accurately calculated, very accurate timers are required (in the order of nanoseconds). As in 802.11 standards the transmitter does not have a common clock with the receiver, one only may be able to measure the Round-Trip Time (RTT), which is the elapsed time between the moment where the last bit of a data block is transmitted, and the associated response (usually an ACK) is received.

As the reader shall have noticed, the ToF is not half of the value of the RTT. Indeed, there is an inherent frame processing time that biases the estimated distance. And if that was not enough, this bias is hardware-dependent and cannot be requested to the client station. In addition, when multipath is present, the time values become random variables and one needs to apply statistical inference and processing to make a robust guess on its value. However, ToF is insensitive to walls and objects. For these reasons, time-based indoor location systems may resolve position with an error of 3-5 m.

Indoor positioning based on Difference Time of Arrival

In this case, we are not concerned about propagation time between transmitter and receiver, or ToF. Conversely, we pay attention to the difference of arrival times between two receivers (APs) which are listening to the same frame from the STA. By drawing two hyperbolas between (at least) 3 APs, one can resolve the position of the STA at the interception point. The precision is fairly good, given the simplicity of this method. The expected resolution is within 1-3m for indoor deployments. The problem of frame processing time, seen in ToF-based methods, disappears due to the subtraction of this processing time on the DToA equations.

However, APs need to know a common clock base, that may be shared via control and management frames. This philosophy fits with the distributed Galgus CHT paradigm, where network nodes share periodic information to optimise their parameters. In any case, time-based methods like ToF or DToA stand on precise time measures (in the order of nanoseconds), and this may be a drawback of this promising idea.

Indoor positioning based on Channel State Information

In the last years, there has been a revolution of the available information which can be gathered from wireless drivers in commercial chips. Specifically, wireless engineers are deeply interested in the CSI matrix, which represents the fine-grain quality of the radio channel for each subcarrier frequency of the OFDM signal. This data is given for each receiver antenna in an AP with MIMO (802.11n and beyond). This valuable information shall be used to detect the Angle of Arrival (AoA) of various signal paths in a reflexive indoor environment. After that, signal processing techniques may be applied to isolate the fastest path, in Line of Sight (LoS) conditions, so as to estimate where does the main energy lobe come from. This promising technique attains sub-metric resolutions in direct vision conditions, and within 2m in No-Line of Sight (NLoS) conditions, so it is considered the most advanced approach to the indoor positioning problem using WiFi.

However, the signal processing methods involved (beamforming, singular value decomposition, inverse problems, array processing techniques, …) are notably expensive in terms of computation resources. Due to that, at this moment the proposed solutions are computed in external specific hardware like DSPs (Digital Signal Processors). The WiFi chip itself has no sufficient computation power to estimate the AoAs and thus solve the positioning problem in real time. In addition, in the state-of-the-art prototypes are only able to locate, at most, only one STA in a complex indoor environment.

Conclusions

Galgus manufactures smart WiFi solutions. We develop technology that enables performance improvement of high-density 802.11 networks, reducing the noise level in the environment, and promoting a more efficient and responsible use of resources.

With its recognised CHT (Cognitive HotspotTM Technology), Galgus provides to various vertical markets a round solution that solves the main challenges that WiFi networks are facing nowadays.

This may have a positive impact on network and services design, bringing benefits to both consumers and building owners.

Modern Wireless Indoor Positioning 1/3 (Introduction)

Estimating one’s own position has always been a central problem in human history. While the need for obtaining the physical position of humans and objects has been an old request for society, it becomes apparent that in the future, the importance of localisation will ever grow. New breakthroughs in sensors, electronics, and information technology, enable ever new applications that demand real-time accurate location information at low cost. Furthermore, many of these applications are situated indoors, as human and machines tend to spend more and more time of their days within buildings.

The fundamental problem of indoor positioning

Besides traditional applications, indoor localisation has experienced additional efforts in recent years with the appearance of ubiquitous computing. In various scenarios, objects and humans must be located or tracked, e.g. in an industrial or medical environment. Additionally, people localisation enables a large number of applications and services. Customers and employees can be observed, intruders detected, elderly people supported, and patients tracked. In public places like subway stations or airport terminals, safety concerns can be addressed by an emergency guidance system. A similar situation may occur in a hotel or in a shopping centre. A guidance system fed with position information of humans may work more efficiently than a blind one. Finally, besides distributed sensing, indoor positioning allows for context-aware information to customers and may improve network efficiency and low power demands.

This article aims to expose current indoor positioning systems based upon existing wireless infrastructure. The deployment of WiFi networks which rely on IEEE (Institute of Electrical and Electronic Engineers) 802.11 standard has experienced an overwhelming success in the last decade, powered by the explosion of high-density networks with users demanding instant, high-quality, multimedia content. It supposes a fast, reliable, and cheap way of providing Internet service to indoor scenarios. Furthermore, it is expected that the number of WiFi connected devices shall grow exponentially in the next decade, as Internet of Things (IoT) penetrates into our society.

“It is expected that the number of WiFi connected devices shall grow exponentially in the next decade”

By installing wireless positioning technology on already deployed infrastructures, the operational cost reduces to the minimum. Thus, network administrators are able to access to a vast variety of information from users within their buildings, obtaining confident analytics and reliable accuracy, while preserving the privacy. However, there are two paradigms for indoor positioning, depending on which devices of the RAN (Radio Access Network) gather and processes the information:

Gathering the relevant information

As the 802.11 standard evolves, it is complemented with amendments which aim to provide novel management mechanisms. We refer the reader to the documents describing 802.11v, 802.11r and 802.11k, among others. They present smart mechanisms for a simple interchange of advanced management and control frames between network nodes. However, this article advocates on presenting feasible solutions for the indoor location problem, even when the devices on the network only support standard WiFi amendments, like 802.11n or 802.11ac standards. This is usually constrained by old STAs, or even by devices which have those advanced features inhibited.

The technological challenge is to obtain the relevant information and to apply it to an estimation algorithm. There are many approaches to the problem, but all are generally based on exploiting the geometry of the network infrastructure. If we know the positions of the APs with respect to a fixed coordinate system, it is sufficient to find the distances from some of them to the desired STA. However, estimating distances in a wireless environment is not straightforward. In fact, there are several electromagnetic phenomena like dispersion, multipath, interferences, fast and slow fading, and things even worse. In addition, the indoor location problem inherently presents a moving and changing environment, where people may be wandering, and furniture and walls may not be fixed.

“If we know the positions of the APs with respect to a fixed coordinate system, it is sufficient to find the distances from some of them to the desired STA”

To overcome these problems, we present here some of the most successful methods for wireless indoor positioning. We have focused on real-world, feasible solutions, which rely on user transparency, and zero changes on the deployment of the WiFi infrastructure. The following four families of methods are arranged from the easiest to the most difficult one:

It should be noted that we have deliberately omitted techniques involving complex and expensive processes like fingerprinting, where one has to create a previous database of all the spots and their corresponding radio propagation features, by manually collecting the data. In addition, these fancy methods do not work when there are obstacles which change their positions, like people or furniture.

In our next articles, we will delve into the details of these promising techniques, as well as show how Galgus combines them to solve the WiFi-based indoor location problem.

Our Research team is focusing on developing novel indoor localisation technology, which together with the benefits of CHT will make your WiFi network perform better than ever, even in the most demanding situations.”

Towards 802.11ac Wave 2

Wave 2: What’s new?

Wave 2 is the second phase of 802.11ac devices, expected to flood the market in 2017. Nowadays, devices that reach the consumers in this second phase of the standard, shall be prepared to implement the most impressive characteristics of 802.11ac. Although some are mandatory, most of them will be optional. And that is the field where the vendors shall differentiate their proprietary solutions.

Comparison between 802.11ac phases: Wave 1 and Wave 2.

Before analyzing in depth each one of these novel features, we may summarize that, in 802.11ac wireless networks:

20 and 40 Mhz channels may be merged if they are contiguous in the spectrum (channel bonding) to create an 80 Mhz channel, or even a 160 Mhz channel (only in Wave 2). This is only possible in the 5 GHz band, due to the inherent saturation of the lower 2.4 GHz band. As you may think, this is one of the reasons of 802.11ac for not operating on the legacy spectrum. With Wave 2, in addition, mechanisms for aggregating two non-adjacent channels of 80 Mhz are included.

By raising the modulation from 64-QAM (6 bits per symbol) to 256-QAM (8 bits per symbol), one can bear 33% more information on the same carriers. This is only achievable if the channel conditions are optimal, from an SNR (Signal to Noise Ratio) point of view. A high SNR usually means that the user is close to the AP (Access Point) and without obstacles between them.

The use of multiple antennas shall bring several and diverse benefits. Before Wave 2, 802.11n and 802.11ac used MIMO for:

However, Wave 2 devices that appear on the market have the chance to add downlink MU-MIMO (from the AP to the user terminals). This allows, for the first time in WiFi networks, to transmit to several users simultaneously, within the same collision domain, without interference. As an analogy of Ethernet wired networks, MU-MIMO transforms the WiFi radio channel from one hub (where only one user may receive at a given time) to a switch, where there is a certain logic so users shall receive different data simultaneously.

“For the first time in WiFi networks, MU-MIMO allows transmitting to several users simultaneously, in the same collision domain, without having interference”

If we have enough antennas, we may combine various of those paradigms to maximize the performance of our network. On one hand, channelization and modulation improvements are relatively easy to implement as an evolution of 802.11n and 802.11ac Wave 1. On the other hand, the magic behind MU-MIMO will be studied further.

Channel bonding

As in previous amendments based on OFDM, 802.11ac Wave 2 divides the available channel onto sub-carriers, each one with 312.5 kHz of bandwidth. They bear an independent bit sequence. Most of them transport user data, but some are dedicated to pilot symbols (known both for the transmitter and the receiver), which help on channel quality measurements.

From 20 Mhz legacy channels in 820.11a, the standard passed to 40 Mhz in 802.11n, and later to 80 Mhz in 802.11ac Wave 1. However, Wave 2 proposes to double the available bandwidth to build a bonded channel of 160 Mhz. In addition, it presents an 80 & 80 Mhz mode to aggregate non-adjacent channels, due to the lack of contiguous free spectrum in the 5 GHz band. Note that several types of civil and military radars work on that band, and their use has priority.

802.11 channels on the 5 Ghz band for Europe (and Japan).

The drawback of using 80 & 80 mode is that, as the channels are far from each other in the spectrum, the device must have duplicated RF (radio frequency) chains, raising considerably the cost and complexity of a deployment. Most of the vendors are sacrificing spatial diversity of MIMO, by using half of the RF chains for each one of the non-adjacent 80 Mhz channels. An AP with 4 antennas shall run on MIMO 4×4 mode (four antennas for transmitting and receiving), unless when it needs the maximum bandwidth and requests 80 & 80 Mhz. In that case, it shall run in MIMO 2×2 mode for each one of the channels.

The fabulous 256-QAM modulation

The increase of the quality of electronics in the RF chains, as well as the channel probing mechanisms, has favored the inclusion of high order modulations like 256-QAM. In QAM modulations, the bit word to be transmitted is mapped to one of the possible symbols of the alphabet. With 256 symbols, we may encode 8 bits within each transmitted waveform, instead of 6 bits (64-QAM modulation), 4 bits (16-QAM modulation), or 2 bits (QPSK modulation). This represents an improvement of at least 33% in spectral efficiency against Wave 1 and legacy releases.

256-QAM constellation on the in-phase and quadrature plane. Comparison with lower order modulations used in modern 802.11 standards.

Thanks to this, two new values of the MCS (Modulation and Coding Scheme) index are available. This physical layer index indicates the modulation and level of protection against errors (code rate) to be used in the transmission. This rate broadly specifies the portion of user information versus the total bits transmitted (the rest is filled with protection bits). The higher this rate (up to 1), the less conservative the transmission, and the better it is supposed to be the radio channel. The assignment has been significantly simplified with regard to 802.11n and can take values between 0 and 9. The last two values (8 and 9) are only unlocked with Wave 2 since they imply a 256-QAM modulation.

“256-QAM represents an improvement of at least 33% in spectral efficiency versus Wave 1 and legacy releases”

Multiuser MIMO

Most of the efforts that have been made over the years to implement Wave 2 solutions on 802.11ac devices are intended to equip APs with downlink MU-MIMO. Certainly, multi-antenna and multi-user communications are capable of separating the collision domains within the radio channel, steering signal where each one of the client terminals is located. To do this, more powerful processors are needed. They shall estimate the state of the channel and adapt the streams of the different transmitting chains in order to form a specific interference pattern.

So far, the MIMO paradigm used in 802.11ac Wave 1 standard was known as SU-MIMO (Single User MIMO), where the AP served data to an exclusive client by using all its antennas to multiplex several spatial streams to the receiver. There was forbidden to send different data to two of three different users at the same time. At most, by using beamforming, one may steer the energy lobe on the interesting direction, and thus gain a few decibels of SNR at the receiver front-end. This shall improve the MCS, and thus the throughput of a single user. However, with MU-MIMO, we can send data to all clients simultaneously, steering different bit streams in the directions of each user.

Comparison between SU-MIMO (left) and MU-MIMO (right) paradigms. With several antennas, one can serve several users at the same time, as long as they are sufficiently separated to form the proper spatial patterns.

How is this done? The theoretical idea behind MU-MIMO has been well known for decades, but until recent advances in technology, it has not been feasible. In order to transmit an OFDM symbol to a particular user (without interfering the others), we shall form a pattern of additive interference just at the point where that user is located, and of destructive interference where the others are. This is known as beamforming and, if we go no further, it has been available for some time in high-end 802.11ac Wave 1 solutions.

“The AP shall form a pattern of additive interference just at the point where that user is located”

However, if we do that for several users, adding the spatial interference patterns, we may send their data stream simultaneously. As said, each user will only get the desired symbol, since the other symbols are attenuated by a pattern of destructive interference at that particular point in space. This works, of course, if the terminals are far enough away from each other. To do that, a protocol is proposed that characterizes the radio channel and acts accordingly, giving instructions to each antenna before transmitting:

The AP sends NDP (Null Data Packet) frames, which do not contain information from higher levels to the different users. These frames intend to probe the radio channel.

Channel probing, feedback, and adaptive beamforming to steer information for each user.

Note that this complex process of adaptive probing has an important computational cost, but it is also expensive from the protocol and spectral efficiency point of view. Nevertheless, MU-MIMO implies several advantages, so nobody doubts that it will be present on the next-generation wireless communication standards for several years.

Conclusions

Galgus manufactures smart WiFi solutions. We develop technology that enables performance improvement of high-density 802.11 networks, reducing the noise level in the environment, and promoting a more efficient and responsible use of resources.

With its recognized CHT (Cognitive HotspotTM Technology), Galgus provides to various vertical markets a rounded solution that solves the main challenges that WiFi networks are facing nowadays. Among the main benefits of our patented technology, we shall highlight that CHT increases network capacity, reduces interference, prevents congestion and slow data rates, reduces EMIs (Electro-Magnetic Interference) to critical systems, and enables automatic configuration – automatic failure detection and recovery.

In this article, we have analyzed the promising improvements introduced by the second phase of 802.11ac devices, namely Wave 2, in the context of advanced wireless communications. Sooner or later, WiFi network administrators will have to study when and how to migrate their technology to Wave 2. The aim of this document is to clarify any doubts that may arise about the advantages of the new phase of 802.11ac standard in a real-world wireless network.

“WiFi network administrators will have to study when and how to migrate their technology to Wave 2”

At this point, it should be clear that 802.11ac Wave 2 presents very attractive enhancements for a WiFi network in terms of throughput, spectral efficiency, and multiuser service. However, the inclusion of a new technology in an already deployed network is always a costly decision. It is true that APs with Wave 2 technology will be cheaper in the coming months, so the network architect should consider when to update their devices. Note that some of Wave 2 most important features, such as MU-MIMO, require terminals on the other end that understand and implement these new features. Other features may be achieved by client software updates, or simply not be available for low-end devices.

In any case, if the administrator has an old and overloaded network, due to the high density of users demanding multimedia content, and is considering on investing to improve performance, the inclusion of APs with the new 802.11ac Wave 2 technology will surely be the better option.

Cognitive Hotspot Technology (CHT)

Background

Access to wireless networks is customer-oriented. That means that the client decides where and when to connect to the network. It is also the logic of the client terminal (STA). It decides autonomously which Access Point (AP) best serves its purposes. Wireless Local Areal Networks (WLANs) are governed by the IEEE (Institute of Electrical and Electronic Engineers) 802.11 standard. Released at the late 90s, it allowed substituting Ethernet wired communications with the well-known WiFi technology. Without the periodic amendments known as 802.11g, 802.11n, and the newer 802.11ac, it would have been out of date in a few years. Fortunately, WiFi networks enjoy better health than ever before, thanks in part to the use of unlicensed spectrum and how cheap and efficient it is to deploy them. And the future is even more promising, thanks to the improvements in the standard that are being proposed at this time.

“Fortunately, WiFi Networks enjoy better health than ever before, thanks in part to the user of unlicensed spectrum and how cheap and efficient it is to deploy them”

However, in this protocol, there is no mechanism that allows the network to decide which AP is the most adequate to serve traffic to a STA. This is one of the lacks of the 802.11 standards: basic devices are not supposed to share information and act in a coordinated way. Without modifications like the ones proposed at Galgus patented technology, the STAs and APs work independently, wasting system resources such as bandwidth, airtime, and transmitted power. Our CHT (Cognitive Hotspot Technology) greatly increases network performance in a clean and elegant way, by allowing APs to measure the radio characteristics of their environment, to share information, and to make smart decisions together, without the need for a master controller.

Cognitive Hotspot Technology (CHT)

CHT is a fully-distributed technology, thereby avoiding the drawbacks and weaknesses of current centralized networks, such as failure of critical nodes (central control nodes) and bottlenecks. Furthermore, CHT has been designed to be a multi-platform technology that can be embedded in access points of any manufacturer.

“CHT converts regular APs into cognitive APs, which are aware of their environment”

CHT converts regular APs into cognitive APs, which are aware of their environment. They proceed continuously sensing the environment to adapt to it. Cognitive APs exchanges information with neighboring APs, managing available resources jointly.

Our software technology is a compound of many different modules, each one in charge of optimizing a specific management task. For example, CHT has specific modules for smart roaming, distributed communications, load balancing, automatic failure recovery, automatic node discovery, automatic channel assignment, advanced security, traffic congestion management, and interference minimization.

CHT is a software product that provides APs with cognitive capabilities, allowing them to sense its environment, exchange information with neighboring WAPs and cooperate between them to ensure efficient use of network resources. It implements a set of features, which, based on its cognitive capabilities, enhance user experience.

CHT paradigm for distributed smart network management.

CHT is composed on the following proprietary algorithms:

Forget the Throughput: Improve the Goodput!

CHT (Cognitive HotspotTM Technology) is an embedded software product that provides the Access Points (APs) with cognitive capabilities, allowing it to sense its environment, exchange information with neighboring APs and cooperate between them to ensure an efficient use of wireless resources. CHT implements a set of functions, which, based on its cognitive capabilities, enhance user experience. As a result, CHT raises spectral efficiency and also improves Goodput up to 400 % (the data rate of successfully delivered packets).

Goodput performance versus the number of clients using only one dual-radio AP.

In any wireless data transmission, a portion of the data will not be delivered to the users due to interferences, congestion, packet collisions, etc. The undelivered data rate is referred to as “Badput” while the successfully delivered portion of the data rate is called “Goodput”. It is considered that a satisfying multimedia service cannot be given if Goodput falls below 97.5%. CHT continuously assesses and optimizes network load and interference levels in real-time to maximize performance and minimize interference. Experiments show that, when all clients decide to connect to the same radio, APs are not able to serve traffic properly to more than 18 clients (2.4 Ghz), or 36 clients (5 Ghz).

“When equipped with CHT, a single AP can maintain up to 90 simultaneous clients”

However, when equipped with CHT, a single AP can maintain up to 90 simultaneous clients requesting a 1Mbps videostream without falling below 97.5% of Goodput. The same AP without CHT and only one active radio may start struggling after just 18 clients connected. Even with both radios active in the absence of CHT, after 53 users connected, performance shall degrade dramatically due to poor interference optimization and no radio balance.

Key features

Smart Roaming (SR)

Smart Roaming (SR) allows transferring users from one AP to another when their SNIR (Signal-To-Noise-and-Interference) falls below a minimum threshold. This minimum threshold is defined as a value that guarantees enough throughput and therefore QoS (Quality of Service) for every client. The user is only roamed in case there is another AP that offers better SNIR to this client. With SR, access points decide to which node a certain user will connect. This is a transparent process since decisions are made by APs and not the user device. If the conditions change, or if the user changes its location, CHT will act in real-time, switching the user to a different access point.

Advanced Load Balancing (ALB)

Load Balancing (LB) allows distributing connected users between the 2 radios of AP, one in 2.4GHz and the other one in 5GHz frequency bands (Intra-AP Load Balancing). Furthermore, Load Balancing distributes connected users among different APs in the network, ensuring there are no bottlenecks (Inter-AP Load Balancing). In this manner, each AP provides service to an optimum number of users, reducing network congestion. The distribution takes into account the type of application that the client is using (streaming, web browsing, etc.), ensuring a high quality of service at all times.

Comparison of user distribution with (right) and without (left) CHT Advanced Load Balancing feature.

Traffic Congestion Management (TCM)

Traffic Congestion Management (TCM) is a mechanism that can identify problematic users who are making an excessive use of the available network capacity. To solve this issue, TCM measures and set limits to control the transmission speed of the problematic client in real-time, ensuring that network resources are fairly shared. TCM acts at wireless level preventing less effective TCP congestion mechanism to trigger and improving overall network performance including wire and wireless networks.

Traffic peaks can be detected and analyzed within CHT Manager.

 Band Steering (BS)

Band steering is used to distribute clients’ stations between the 2.4GHz frequency band and the 5GHz frequency band depending on the channel occupancy at each band. This is very useful in current Wi-Fi networks due to the saturation of the 2.4GHz frequency band, which is also used by other technologies like Bluetooth, very crowded due to the rising of IoT.

Band Steering with only one AP. Clients are properly distributed among the available radios.

Automatic Channel Assignment (ACA)

Automatic Channel Assignment (ACA) is a feature that automatically and dynamically assigns transmission channels to a group of APs, selecting the channel configuration that reduces to the minimum level of interference in the network and therefore increases overall throughput. It works continuously, reacting to any changes in the environment, such as the activation of an additional access point internal or external ones. As conditions constantly change, suddenly our perfectly configured network doesn’t work as expected. With CHT, APs detect the interference source (WiFi or non-WiFi) and recalculate the new optimum channel assignment.

The PTQ-15-07692 project closes its first year successfully!

The project PTQ-15-07692, funded by the Spanish Government’s Torres Quevedo grant, has successfully completed its first year.

The project, entitled “Study of performance optimization of WiFi wireless networks in high user density environments by applying blind interference cancellation techniques in MU-MIMO systems”, aims to study and implement methods to improve interference mitigation in WiFi environments, focusing on 802.11ac and 802.11ax standards.

To this end, in this first year we have studied in depth the recent advances in the state-of-the-art regarding machine learning and signal processing techniques for interference cancellation, as well as the new 802.11 standards (trade name WiFi).

In addition, a simulation environment has been developed to test algorithms, implementing key features of the physical and MAC layers of the standard, including MIMO, OFDM, frame injection and multipath propagation, among other characteristics.

During the second year, the chosen algorithms will be simulated and real implementation in a real laboratory prototype using Software-Defined Radios (SDRs) will be explored.

Galgus partners with Landatel

Both companies have reached an agreement to manufacture and commercialize high-capacity Wi-Fi connectivity solutions for high-user density areas.

Internet consumption has undergone through a major change in recent years due to the generalization of the use of smartphones and the consumption of content formats such as video streaming. This has led to a saturation of Wi-Fi networks, especially in high-density areas of connected devices, such as transport, commercial or business areas, residential or educational environments and the industry sector 4.0, which ends on a bad user experience.

In this context, Landatel and Galgus, have allied to launch a new platform that converts access points into smart equipment capable of managing network resources jointly by multiplying by five the performance of the system without cuts or interruptions in the connection.

“With CHT (Cognitive HotspotTM Technology) the access points measure and share everything that happens around them to make joint decisions without the need for a controller”. explains José González CEO of GALGUS.

The magic of WiFi: 802.11 Evolution

Wireless networks based upon IEEE (Institute of Electrical and Electronic Engineers) 802.11 standard, have experienced an overwhelming success since its first versions, two decades ago. In practice, the data rates have been multiplied by 1000, providing smart, reliable, and fast RANs (Radio Access Networks).

Despite early intents, 802.11a was the first successful standard published in 1999. The proposed modulation was OFDM (Orthogonal Frequency Division Multiplexing), with 52 subcarriers for the PHY (Physical channel). It operated on 5 Ghz frequency band, and it was stated to achieve up to 54 Mbps. Nevertheless, its implementation was an enormous technological challenge, so the release was delayed several months, and gave time to a strong establishment of 802.11b.

On his part, 802.11b appeared the same year. It worked on the 2.4 Ghz band, but using spread spectrum techniques like DSSS (Direct-Sequence Spread Spectrum) to access the radio channel. It achieved a rate up to 11 Mbps and had a larger coverage area than 802.11a, but unfortunately it was subject to more interference. The reason was the shared spectrum with cordless phones, Bluetooth, microwave ovens, and many other technologies that operate within the same frequency band.

802.11g arrived in 2003, merging the best characteristics from both standards: it operated on the 2.4 Ghz band, but used OFDM modulation to access the radio channel, obtaining again up to 54 Mbps. It was backward compatible with previous technologies and promoted the settlement of WLAN (Wireless Local Area Network) technologies as a reliable and cheap substitute of Ethernet. Dual band a/b/g products fastly spreaded through the market, and accelerated in a notable manner the standardization of WiFi devices within the 802.11 framework.

Being WiFi the absolute king of local wireless communications, 802.11n was released in 2009. Also known as HT (High Throughput), it announced data rates up to 600 Mbps. To achieve this, it proposed for the first time the use of multiple transmission and reception antennas, which was known as MIMO (Multiple-Input, Multiple Output). It also allowed to aggregate legacy 20 Mhz channels in pairs (40 Mhz) under user request. This channel bonding policy was going to become a frequent improvement in the next releases of the standard. In addition, it proposed STBC (Space-Time Block Coding) and beamforming (which was not widely implemented due to technical difficulties) to improve robustness and coverage area of the radio signal. So much expectation was created that 802.11n compatible products arrived at the market even before the standardization process was completed.

802.11ac is the latest version of the WiFi standard for WLANs. It was approved in 2013, and it defines how the standard shall implement VHT (Very High Throughput) networks, with the aim of achieving data rates of several Gigabits/sec. It operates exclusively on the 5 Ghz band, and it allows bonded channels of 80 and even 160 Mhz. In addition, it raises the modulation order in optimal conditions up to 256-QAM (Quadrature Amplitude Modulation). However, its biggest step forward is the extended use of MIMO, supporting up to 8 antennas transmitting and receiving, adaptive beamforming, as well as downlink MU-MIMO (MultiUser MIMO). Later in this document, we will review these technologies. Some of these improvements were a major engineering challenge, so the market release has been splitted into two phases: Wave 1 at the end of 2013 with the basic features (which are a substantial improvement over 802.11n), and Wave 2 with advanced features in 2016.

The biggest step forward is the extended use of MIMO, supporting up to 8 spatial streams, adaptive beamforming, as well as downlink MultiUser-MIMO.

As expected, the throughput rises substantially when introducing better modulations, larger channel bandwidth, and more transmitter/receiver antennas. On that, it shall be noted that this effective throughput is calculated for the better channel conditions, and for only one user. However, we can get closer to this upper bound when using the newest devices available.

AOIFES is boosting wireless performance in all possible WiFi scenarios thanks to CHT. Our APs are equipped with the latest 802.11ac Wave 2 technology, which together with the benefits of CHT will make your WiFi network perform better than ever, even in the most demanding situations.
