description A radio frequency identification (RFID) tag is provided with a capability to adaptively initiate a floating RF threshold from the level of a raw RF signal detected during a communication session with a designated RFID reader, and to compare that threshold with the level of a baseband signal derived from the RF signal so as to reject RF interference including noise from other sources during the communication session. Preferably, the threshold is derived from the peak level of the detected RF signal on commencement of each communication from the reader during the session.
