Abstract:
1. A system for communicating with an RFID transponder comprised of: a transceiver having at least a receiver portion and a transmitter portion, wherein said receiver portion has an adjustable gain capable of varying amplification of a signal detected by said receiver portion, wherein and said transmitter portion has an adjustable strength electromagnetic interrogation signal used to encode information into or read information from said RFID transponder; a signal-to-noise ratio module in communication with said transceiver, wherein said signal-to-noise ratio module determines a signal-to-noise ratio of a signal received by said receiver portion of said transceiver; and an adaptive control module in communication with said signal-to-noise ratio module and said transmitter portion and said receiver portion of said transceiver, wherein based upon said signal-to-noise ratio, said adaptive control module: wherein said system encodes said RFID transponder that originated said signal used to determine said signal-to-noise ratio.
