the wireless communication system. The wireless device further includes a
receiver for receiving a second signal from the transponder, where the
second signal includes identifying data associated with the transponder.
The wireless device further includes a processor for determining a
location of the wireless device within the environment or classifying the
environment based at least in part upon the received identifying data.
