US 2013/0257598 A1 · INTERFERENCE DETECTION AND MITIGATION IN RFID READERS AND SYSTEMS

Abstract

One embodiment of the present invention includes a Radio Frequency Identification (RFID) reader configured to detect radio frequency (RF) interference in and/or outside a band of RFID operation. The RFID reader includes a receive channel for receiving incoming RF signals; and hardware for detecting interference in and/or outside a band of RFID operation. A method for mitigating radio frequency (RF) interference in and/or outside a band of RFID operation, according to one embodiment, includes detecting interference in and/or outside a band of RFID operation; and controlling an aspect of operation of the RFID reader for mitigating the detected interference.
