A self-assignment method for assigning detector and working devices among a plurality of access devices in a wireless network begins by performing wireless data collection with the access devices during an automated calibration period. During this time, each access device receives beacons from one or more other transmitting access devices. The method records radio frequency (RF) data associated with beacons received during the wireless data collection, and thereafter automatically designates at least one of the access devices as a detector device, based upon the recorded RF data.
