Abstract:
1. A method for Access Point location discovery in an unmanaged network, the method comprising: scanning, by an interested Access Point (AP), a neighboring AP for a Media Access Control (MAC) address and radio channel belonging to the neighboring AP; querying, by the interested AP from the neighbor AP, a location of the neighboring AP using the scanned MAC address and radio channel; receiving, at the interested AP from the neighboring AP, the location of the neighboring AP; performing, by the interested AP, a Fine Timing Measurement (FTM) by calculating a Time-of-Flight (TOF) distance measurement; validating, at the interested AP, the received location of the neighboring IP against the ToF distance measurement; and assigning a reliability grade to a location according to the number of times the same AP was reported with the same location by different APs in a network.
