Abstract
Described is an RFID tracking system, an RFID tag and method. The tag includes a memory storing identification data and a radio frequency transceiver receiving a signal from a first wireless transceiver. The first wireless transceiver is part of a wireless wide area network WWAN). The radio frequency transceiver transmits a response signal including the identification data to at least one second wireless transceiver. The at least one second wireless transceiver being part of a wireless local area network WLAN). A location of the RFID tag is determined as a function of the response signal.
Claims23
An RFID tag, comprising:
- a memory storing identification data;
- and
- a radio frequency transceiver receiving a signal from a first wireless transceiver, the first wireless transceiver being part of a wireless wide area network (WWAN),
- wherein the radio frequency transceiver transmits a response signal including the identification data to at least one second wireless transceiver, the at least one second wireless transceiver being part of a wireless local area network (WLAN), and
- wherein a location of the RFID tag is determined as a function of the response signal.
An RFID tag, comprising:
- a memory storing identification data;
- and
- a radio frequency transceiver receiving a first signal from a first wireless transceiver, the first wireless transceiver being part of a wireless wide area network (WWAN),
- wherein the radio frequency transceiver transmits a first response signal including the identification data to the first wireless transceiver,
- wherein the radio frequency transceiver receives a second signal from a second wireless transceiver, the second wireless transceiver being part of a wireless local area network (WLAN),
- wherein the radio frequency transceiver transmits a second response signal including identification data to the second wireless transceiver, and
- wherein a location of the RFID tag is determined as a function of the second response signal.
A computer-readable storage medium storing a set of instructions, the set of instruction capable of being executed by a processor, the set of instructions performing the steps of:
- initiating transmission of a signal to an RFID tag over a first transceiver of a wireless wide area network (WWAN);
- receiving a response signal from the RFID tag via a second transceiver of a wireless local area network (WLAN);
- and
- determining a location of the RFID tag as a function of the response signal.
