Abstract
A method and system for exchanging data between one or more RFID readers and one or more non-tag devices in an RFID system using RFID air interface protocol. An RFID system includes one or more non-tag devices in data communication with one or more RFID readers over an interrogation zone. Non-tag devices utilize RFID air interface protocol to transmit and receive wireless data signals to and from the RFID readers, obviating the need to implement a separate communication infrastructure. The RFID readers may forward the data to an RFID backscatter enabled host computer for processing the received signals. Non-tag devices acting as readpoints communicate with other non-tag devices to establish a parent/child readpoint hierarchy. One or more multiplexers may facilitate the data exchange between RFID readers and the non-tag devices in order to provide an even more robust communication network.
