Abstract
Systems (100) and methods (400) for determining a Handheld Reader's (“HR”) location within a facility. The methods involve: performing first operations by HR to read RFID tags having locations within the facility that are unknown to the handheld reader; performing second operations by HR to receive signals from RF Enabled Devices (“RFED”) located at known locations within the facility; and determining HR's location/orientation using RSSI levels or TOF values of signals received from RFEDs, known locations of RFEDs, sensor data, known antenna patterns of RFEDs, a known antenna pattern of HR, and/or (9) information indicating which RFID tags were read by HR and at least one RFED. The first and second operations are performed while HR is being carried by a person throughout the facility.
