Patent ID: 7825804

Claim:
A radio frequency identification (RFID) system comprising: a location trigger configured to transmit a trigger location; a first RFID reader coupled to the network and having a first antenna associated therewith, the first reader configured to read a first set of tag IDs within a first range of the first antenna; a second RFID reader coupled to the network and having a second antenna associated therewith; the second RFID reader configured to read a second set of tag IDs within a second range of the second antenna; an RF switch coupled to the network and configured to receive the trigger location, and to receive the first set of tag IDs and the second set of tag IDs from the first RFID reader and the second RFID reader; the RF switch configured to reconcile, using a locationing algorithm dependent on the ranges of the RFID readers, the location of an asset having a particular tag ID when the particular tag ID is an element of both the first set of tag IDs and the second set of tag IDs, wherein if the location trigger specifies that an asset including the particular tag ID is at different coordinates than determined by the locationing algorithm, then the locationing algorithm is modified to bias a location of the asset towards the trigger location received by the RF switch.
