Patent ID: 8451119

Claim:
A method of adjusting operation of an RFID tag for an environment, the method comprising: receiving an input associated with a sensed aspect of the environment, the input selected from the set of: an expected number of RFID tags within the environment; a velocity of the RFID tag; electromagnetic noise within the environment; presence of one or more RFID readers within the environment; humidity within the environment; temperature within the environment; and an electromagnetic reflection property of the environment; sending an instruction to the RFID tag based on the input, the instruction encoded in a TUNE command and causing the RFID tag to perform one of the following: turning a sub-circuit of the RFID tag's semiconductor chip on; turning a sub-circuit of the RFID tag's semiconductor chip off; altering a bias current within a sub-circuit of the RFID tag's semiconductor chip; altering a bias voltage within a sub-circuit of the RFID tag's semiconductor chip; and, adjusting a threshold within a sub-circuit of the RFID tag's semiconductor chip.
