ABSTRACT:
A system and method of scheduling RFID tag interrogations by a plurality of RFID readers so as to mitigate the effects of interference within an RFID environment in which the readers are deployed, and to enhance the efficiency and reliability of the overall RFID system. The system includes a plurality of RFID receivers for receiving RFID tag data, a plurality of RFID tag interrogators for transmitting RF interrogation signals for interrogating RFID tags, and a controller for providing to at least one interrogator, at least one receiver, and at least one tag, a parameter associated with operational characteristics of the interrogator, the receiver, and the tag, respectively. The interrogator, the receiver, and the tag are operative, in response to receipt of the respective parameter, to modify its operational characteristics in accordance with the respective parameter, thereby avoiding interference at the receivers and the tags.
