RFID SYSTEM WITH SELECTABLE BACKSCATTER PARAMETERS

摘要

A RFID tag for use in an RFID system is disclosed. The RFID tag comprises an antenna operable to receive a carrier wave from an RFID reader. A state machine is coupled to the antenna and receives a backscattering command comprising a backscattering parameter for the RFID tag to use for backscattering the carrier wave. A modulator is coupled between the antenna and the state machine. The modulator produces a modulated backscatter signal, based at least partially dependent on the backscattering command.
