Abstract

A method of communicating between a transponder (12..18) and an interrogator (20) includes transmitting an announcement signal (34) from the transponder (12..18) to the interrogator (20), the announcement signal (34) including an identification code associated with the transponder (12..18), the communication signal including at least a portion of the identification code of the transponder (12..18) or a derivative thereof, thereby enabling the transponder (12..18) to identify the communication signal from the interrogator (20) as being directed at the transponder (12..18).
