Abstract
Abstract A multi-interrogator transponder arrangement is disclosed. The transponder arrangement comprises a first interrogation unit (10) comprising a first wireless datacom transceiver (19) which transmits at least one RF interrogation signal. The arrangement also comprises a second interrogation unit (16) comprising a second wireless datacom transceiver which is in wireless communication with the first wireless datacom transceiver 19. The arrangement still further comprises a responder unit (12) which upon receipt of the RF interrogation signal transmits data stored therein back to the first interrogation unit 10 in the form of a responsive RF communication, the responder unit (12) comprising a responder unit energy accumulator (136) which stores energy contained in the RF interrogation signal. Other devices, systems and methods are also disclosed.
