Abstract
A radio frequency tag for a radio frequency identification system is provided that includes an antenna and a receiver coupled to the antenna. The receiver receives and demodulates a message received on at least one frequency. A retransmit controller receives the message, determines a retransmit status for the message, and if the retransmit status is positive, initiates retransmission of the message for reception by another radio tag.
