Patent ID: 8610543

Claim:
A radio frequency identification (“RFID”) packet radio system, the RFID packet radio system comprising: an antenna; a radio, the radio configured to receive and transmit packet radio signals and RFID signals, the receiving and the transmitting of the packet radio signals and the RFID signals occurring at a first frequency; a processor, the processor configured to be in communication with the radio and to perform signal detection and demodulation, the processor configured to receive an RFID signal at the first frequency; a transmit path, the transmit path configured to transport a packet radio signal to be transmitted and an RFID signal to be transmitted, from the radio to the antenna; a first receive path, the first receive path configured to transport a received packet radio signal from the antenna to the radio; a second receive path different from the first receive path, the second receive path configured to transport a received RFID signal from the antenna to the processor; and a coupling mechanism, the coupling mechanism in the transmit path and the second receive path and configured to simultaneously transmit a first RFID signal and receive a second RFID signal enabling the RFID packet radio system to operate in a full duplex mode.
