    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.

    Abstract: A radiofrequency identification (RFID) multiplexer, which may be in a network, interprets an RF signal from an RFED reader as RFE) tag interrogation data. A single cable directs an RF signal from the RFID reader and RF control signals and/or RF power through the multiplexer. An RF sampler may be coupled to the cable; and an RF detector detects the RF signal from the cable via the RF sampler. A data decoder decodes and interprets the RF signal as the RFID tag interrogation data and forwards the RFID tag interrogation data to a control logic circuit as a MUX channel-change command. The logic circuit and decoder may be combined in a microcontroller, and an RF backscatter modulator coupled to the cable enables reverse communication with the RFID reader to determine whether another RFID multiplexer is coupled to the RFID multiplexer.

    Abstract: An RFID detection system for determining the location of tagged items within an interrogation zone. The system includes one or more printed circuit boards coupled to each other and placed within a region of the interrogation zone. Each printed circuit board contains an antenna array having one or more antennas where each antenna detects the presence of one or more tagged items within a specific read zone in the region. The printed circuit board also contains a multiplexer coupled to the antenna array, where the antenna array and the multiplexer are provided on a substrate. Upon an interrogation request from an RFID reader, a specific antenna can be activated and selected by the multiplexer and tagged items within the antenna's read zone are interrogated. RF signals containing RF identification information are then transmitted back to the RFID reader where a host computer interprets the signals and determines the location of the identified tagged items.
