Claim Text:
1. A method for inventorying a Radio Frequency Identification (RFID) tag comprising: communicating, from a controller, a target location to a first synthesized-beam RFID reader and to a second synthesized-beam RFID reader; steering, responsive to the communicated target location, a first beam from the first synthesized-beam reader to the target location and a second beam from the second synthesized-beam reader to the target location; transmitting, simultaneously, from the first synthesized-beam reader a modulated RF inventory signal and from the second synthesized-beam reader a substantially unmodulated RF signal; receiving, responsive to the modulated RF inventory signal, a tag reply at one of the first and second synthesized-beam readers; and transmitting, from one of the first and second synthesized-beam readers, a modulated RF acknowledgment signal responsive to the tag reply, and from the other of the first and second synthesized-beam readers a substantially unmodulated RF signal.
