摘要： A method and apparatus for selectively reading radio frequency identification device (RFID) tags by an RFID reader includes the RFID reader transmitting an interrogation signal at each of a plurality of power levels beginning with a lowest power level and sequentially increasing power of the transmitted interrogation signal to a highest power level. The RFID reader receives, in response to transmitting the interrogation for at least one of the power levels, at least one data signal from each RFID tag within a read zone of the RFID reader, wherein each of the data signals contains stored data corresponding to the RFID tag responding to the transmission of the interrogation signal. The RFID reader selectively reads the stored data contained in the data signals received from the responding RFID tags.

摘要： Methods and apparatus are provided for locating a mobile terminal in an RFID environment. The apparatus comprises a communicator coupled to the mobile terminal for instructing the terminal to enter a LOCATE mode, an RFID transceiver in the terminal that interrogates RFID tags while in the LOCATE mode to obtain information therefrom correlatable with their known positions, and a processor coupled to the RFID transceiver for determining the terminal location based at least in part on such information. Location determination may take place either in the terminal or a local network server or both. The tags may be either fixed position infrastructure tags or item tags that have been mapped in the local server or the terminal. Once the terminal location is determined, the terminal and/or server may announce and/or broadcast the terminal location.

摘要： Methods and apparatus are provided for locating one among many items equipped with RFID tags. The apparatus comprises a portable system interrogating the RFID tags and receiving responses therefrom that depend at least on their bearing angle. A comparator selects responses from the one item and ignores others. An annunciator indicates the presence of the one item in the interrogator field of view and, desirably but not essentially, its relative proximity. A directional antenna whose beam pattern is limited in azimuth and/or elevation provides bearing angle information. Its field of view becomes progressively smaller as the antenna approaches the one item so that a user can substantially pinpoint its location without needing any of the usual RFID infrastructure. Tag response hit rate and/or signal strength provides range related information to the interrogator. Optionally, the presence of each new tag is announced until all new tags have been identified.
