Abstract:

A system and method uses wireless communication devices as beacons to determine the relative location of another target wireless communication device. The beacons transmit identifying information that the target device can use to determine the identity of the beacon. The target device can measure the received intensity of the beacon transmissions and determine an associated beacon that best satisfies a specified criteria (e.g., largest signal strength) using a procedure of the present invention that discriminates between multiple beacons.
