Abstract
A wireless local access network (WLAN) radio listens for a beacon for a listening duration on each of multiple channels. Periodically, the WLAN radio changes the channel on which the WLAN radio listens for a beacon. The WLAN radio rotates through all channels until an entire beacon period is listened to. The number of iterations is chosen to minimize the overlap of successive listening durations. The WLAN radio can detect a beacon by detecting an incomplete portion of a beacon.
