Abstract
An RFID reader for communicating with an RFID tag and with a remote RF transceiver. A single transceiver is employed for communicating with RFID tags and with a remote RF transceiver. A single antenna is coupled to the transceiver. In a first mode, the transceiver communicates with the RFID tags via the antenna, on a first frequency. In a second mode, the transceiver communicates with the remote RF transceiver via the same antenna, on the first frequency or a second frequency.

31. A method for combining an RFID reader and an RF backhaul transceiver comprising:
-
controlling a single transceiver to alternatively;
(a) communicate with one or more RFID tags on a first frequency via a single antenna, and (b) communicate with a remote RF transceiver on the first frequency or a second frequency via the single antenna;
wherein the single transceiver is controlled using a switching device which performs the additional steps of;
coupling the antenna to a first pole of a double pole, single throw switch, and coupling a receiver to a switching element of the switch which is selectively connected to either a second pole of the switch for sending signals to and receiving signals from the RFID tag, or connected to the first pole of the switch for sending signals to and receiving signals from the remote RF transceiver;
wherein the switching device comprises the double pole single throw switch and a signal directing device having a first port coupled to a transmitter, a second port coupled to the antenna, and a third port coupled to the first pole of the switch. - View Dependent Claims (32, 33, 34, 35, 36)
