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.
