Abstract: A radio frequency identification (RFID) system for item level inventory and a method for performing an RFID item level inventory may be provided. The method may include selectively controlling with an RF signal each of a plurality of multiplexers connected to a plurality of local antennas and selectively enabling with an RF signal the plurality of local antennas using the plurality of multiplexers to perform RFID interrogation on a plurality of RFID tags. The method further may include acquiring inventory information based on the RFID interrogation.

Abstract: A radio frequency identification (RFID) system for item level inventory m ay be provided. The RFID system may include an RFID interrogator, at least o ne interrogator antenna and at least one local antenna configured to communi cate with RFID tags. The RFID system further may include a multiplexer conne cted to the at least one local antenna and configured to receive power from an RF signal generated by the RFID interrogator and transmitted wirelessly f rom the interrogator antenna.

Abstract: A method and system for exchanging data between one or more RFID readers and one or more EAS system devices in an RFID system using RFID air interfac e protocol. An RFID system includes one or more EAS system devices in data c ommunication with one or more RFID readers over an interrogation zone. EAS s ystem devices utilize RFID air interface protocol to transmit wireless data signals, which may include alarm event data, to the RFID readers, obviating the need to implement a separate communication infrastructure. The RFID read ers may forward the alarm event data to an RFID backscatter enabled, host co mputer for processing the received signals. The host computer may then sched ule further interrogation of inventory items at locations where an alarm eve nt has occurred. One or more multiplexers may facilitate the data exchange b etween RFID readers and the EAS system devices in order to provide an even m ore robust communication network.
