摘要： Systems and methods of using RFID tags and a mobile RFID reader device for determining a geographic position of assets within a prescribed region is provided. A method of inferring the geometric location of assets within a prescribed region comprises the steps of moving a mobile RFID reader through said prescribed region; wirelessly detecting, by the mobile RFID reader, a first RFID location transponder while moving through said prescribed region; wirelessly detecting, by the mobile RFID reader, at least one RFID asset tracking transponder while moving through said prescribed region; wirelessly detecting, by the mobile RFID reader, a second RFID location transponder while moving through said prescribed region; and determining the geographic location of assets associated with said at least one detected RFID asset tracking transponder based upon said detected first and second RFID location transponders and a known position and identification code of said first and second RFID location transponders.
