Abstract: A method, system and apparatus for generating a cancellation signal in a RFID reader to isolate a transmit section and a receive section of a RFID reader, where the RFID reader generates a local reference signal from a broadcast transmit signal, receives a receive signal from a remote device, determines at least one correction factor, e.g., an amplitude correction factor, to generate a cancellation signal. The method, system and apparatus can further include combining a cancellation signal and a receive signal to minimize or cancel out interference and noise on the receive signal.

Abstract: A radio frequency identification (RFID) system (100) and method for communication with at least one radio engine module (102) ("REM"). The system and method including at least one radio engine module (102), where the at least one radio engine module has a signal generator (120) for synthesizing radio frequency signals to be transmitted to one or more remote communication devices (110) and a receiver (124B) for receiving radio frequency signals transmitted by one or more remote communication devices. The RFID system and method further include a controller (108) that is separate from and in communication with the at least one radio engine module, which manages the transmission of information with the at least one radio engine module (102).
