Claim of US Patent No. 9,936,520

1. In a communication system including a plurality of Wi-Fi clients operably connected to one or more Wi-Fi Access Points for connection to a core network, the Wi-Fi Access Points operably connected to a Wi-Fi controller, a method comprising the Wi-Fi controller:receiving M1 and M2 associated with a plurality of Wi-Fi clients,
wherein, for a respective Wi-Fi client configured to operate on a channel:
M1 is a Received Signal Strength Indication (RSSI) from a serving Wi-Fi Access Point, measured by the Wi-Fi client, and
M2 is an aggregated level of interference from other than the serving Wi-Fi Access Point, measured by the Wi-Fi client;
receiving M3 associated with a plurality of Wi-Fi Access Points,
wherein, for a respective Wi-Fi Access Point:
M3 is a level of interference measured by the Wi-Fi Access Point received from other of the plurality of Wi-Fi Access Points operating on the channel;
generating distributions of M1, M2 and M3 including progressive updates of M1, M2 and M3; and
setting and updating a Clear Channel Assessment-Energy Detection (CCA-ED) threshold and a Clear Channel Assessment-Carrier Sense (CCA-CS) threshold based on the distributions of M1, M2 and M3.
