  • Method and system for improving reading range of FDX RFID tags
    Patent number: 9355287
    Abstract: A system and method comprising an RFID scanner, a reader or an interrogator for interrogating a transponder of a desired RFID tag to be interrogated; a transmission device for transmitting a desired carrier signal toward the RFID tag to be interrogated; a receiving device for receiving an RFID signal from the RFID tag to be interrogated; a processing device for removing the carrier signal from the RFID signal and thereby leaving an encoded data field of the RFID tag to be interrogated and processing the encoded data field for determining a start bit sequence of the encoded data field for at least one scan; and an averaging device for averaging the encoded data fields of at least two scans with one another and facilitate reading the encoded data field of the RFID tag to be interrogated.
