Abstract
In settings where multiple access points (APs) provide WiFi coverage, the radio frequency (RF) environment experienced by a client device is non-stationary due to various factors such as the emergence and disappearance of hotspots; spectrally uncoordinated APs; the number of clients; the sensitivity of client devices to noise; the mutual distances between clients, RF noise sources, and metallic structures; etc. Since the RF environment experienced by a client device is materially different from that experienced by an AP, attempting to optimize network parameters based on measurements at the AP frequently fails or further degrades WiFi service. This disclosure describes techniques to automatically control and adjust the settings of a network of APs to optimize WiFi coverage and quality based on measurements made by external devices. The measurements include factors such as the RF noise, RSSI, and SNR ratio at locations close to client devices in the WiFi coverage area. Network optimization is carried out based on the measurements, ensuring settings selection in a client-centric, rather than AP-centric, manner.
