Encoded information reading system including rfid reading device having multiple antennas

摘要: An encoded information reading (EIR) system can comprise a microprocessor, memory, and at least one RFID device, all communicatively coupled to bus. The EIR further two or more external antennas electrically multiplexing circuit. circuit be configured couple each antenna the device by using time division method frequency method. disposed according spatial pattern provide spatially continuous signal reception within pre-defined area volume. receive signals from plurality of tags attached items radio range antennas. store in its memory responses received tags.
