Abstract
A receiver/transmitter device for logistics tracking configured to monitor or detect a shipment unit includes: a cellular transmitter for transmission of wireless signals via a cellular network; an ultra-wide band (UWB) transmitter for transmission of radio signals over a short-range network; a radio frequency identification (RFID) reader configured to detect a passive RFID tag associated with the shipment unit; and a processor in communication with the cellular transmitter, UWB transmitter, and RFID reader. The processor is configured to selectively cause the cellular transmitter or the UWB transmitter to wirelessly transmit information detected by the RFID reader to a remote computing device or computer server. The device also includes a housing configured to be mounted to a transport platform that encloses the cellular transmitter, UWB transmitter, RFID reader, and processor.
