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