Abstract
Systems (100) and methods (400) for determining a location of an object within a facility. The methods involve: performing operations by beacons to illuminate a plurality of Zone-Of-Interests (“ZOIs”) including objects within the facility; performing operations by a handheld reader to read RFID tags coupled to the objects; performing operations by a beacon receiver to obtain a first location identifier transmitted from a first beacon while the handheld reader is reading the RFID tags; using the first location identifier to determine approximate locations of the RFID tags which were read in time proximity to the beacon receiver's reception of the location identifier; and optionally generating a three dimensional map showing locations of the RFID tags. Notably, the beacon receiver is an accessory of the handheld receiver or a standalone device worn by an operator of the handheld device.
