Claim 9:
10. A system for locating a radio-frequency identification (RFID) tag, the system comprising:
a plurality of antennas configured to transmit activation signals toward the RFID tag and to receive responses to the activation signals from the RFID tag; and
a processor operably coupled to the plurality of antennas and configured to estimate possible solutions for a location of the RFID tag based on the responses to the activation signals and determine that one of the possible solutions for the location of the RFID tag is a valid solution based on an assumption about a location of the RFID tag,
wherein the processor is further configured to determine, from historical data, a previous location of the RFID tag relative to other RFID tags and the plurality of antennas is configured to isolate transmission of the activation signals to a volume containing the previous location of the RFID tag.
