Method and apparatus for Wi-Fi access optimization

A method for controlling a plurality of Wi-Fi clients and a plurality of Wi-Fi Access Points (APs) is provided. The method receives M1 and M2 for the Wi-Fi clients and M3 for the Wi-Fi APs. 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 AP and M2 is an aggregated level of interference from other than the serving Wi-Fi AP. For a respective Wi-Fi AP, M3 is a level of interference received from other of the Wi-Fi APs operating on the channel. The method generates distributions of M1, M2 and M3, sets 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, and transmits the thresholds to the Wi-Fi clients and Wi-Fi APs.
