Abstract
Systems and methods for spatial reuse in a deployed wireless area network (WLAN) include identifying a plurality of competing APs of an external wireless network operating on a same channel as a deployed AP of a deployed wireless network; examining the received signal strength indicator (RSSI) of the identified plurality of competing APs of the external wireless network; filtering out selected one or more of the identified plurality of competing APs of the external wireless network based on their respective RSSIs to arrive at a filtered set of competing APs; and augmenting a spatial reuse group (SRG) of the deployed AP to include the APs in the filtered set of competing APs in the SRG.
