Claim 15:
16. A method of locating a radio-frequency identification (RFID) tag, the method comprising:
determining, by a processor, a previous location of the RFID tag relative to other RFID tags based on historical data;
determining a volume of interest based on the previous location of the RFID tag relative to the other RFID tags;
scanning, by a plurality of antennas operably coupled to the processor and mounted from a ceiling, activation signals with powers and/or phases selected based on the volume of interest across the volume of interest;
receiving, by the plurality of antennas, responses to the activation signals from the RFID tag;
determining, by the processor, possible solutions for a location of the RFID tag based on the responses to the activation signals; and
determining, by the processor, that one of the possible solutions for the location of the RFID tag is an invalid solution based at least in part on an assumption about a location of the RFID tag with respect to the ceiling.
