Abstract
A method and apparatus for efficiently processing packets from neighboring basic service sets (BSSs) to characterize the traffic within a wireless local area network (WLAN), mesh network, or similar wireless communication system is disclosed. The apparatus may be an access point (AP) in a BSS which includes a measurement period (MP) interval timer, a promiscuous measurement period (PMP) timer and a receiver filter. An interval of the MP interval timer is set while the receiver filter is enabled. During the interval, the AP only processes packets which originated from the AP's own BSS. When the MP interval timer expires, a value of the PMP timer is set to a predetermined time duration and the receiver filter is disabled. During the predetermined time duration, the AP processes all received packets irrespective of which BSS the packets originated from. The receiver filter is again enabled when the PMP timer expires.
