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).
