Abstract

A location tracking apparatus and method are disclosed. In one embodiment, the method comprises receiving information from each repeater indicating which packets wirelessly transmitted by a mobile station were received by each repeater including received signal strength of each of those packets, and determining location of the mobile station with respect to the repeaters based on power levels of individual wirelessly transmitted packets received at the repeaters.

Claims

1. A method comprising:

receiving information from each of a plurality of repeaters indicating which of a plurality of packets wirelessly transmitted by a mobile station were received by each repeater including received signal strength of each of the wirelessly transmitted packets at said each repeater; and

determining location of the mobile station with respect to the plurality of repeaters based on power levels of individual packets of the plurality of wirelessly transmitted packets received at the plurality of repeaters.
