Abstract
Embodiments presented herein describe a location aware, RFID-enabled pallet mover for tracking inventory moving in a warehouse. The pallet mover includes a RFID system for detecting a pallet currently loaded on the pallet mover and a real-time location system (RTLS) tag for identifying a location of the pallet mover in the warehouse. In one embodiment, the RFID system includes an antenna and an RFID reader for detecting RFID tags in order to track inventory such as a pallet or packages. The RFID reader can communicate with the RFID tags in the environment to identify which pallet is currently loaded on the mover. In one embodiment, the RFID system waits until the pallet mover is moving before activating the RFID reader and monitoring a received signal strength indicator (RSSI) of an RFID tag to determine whether the corresponding pallet is currently loaded onto the pallet mover.
