Identification and location of personal area network device

A wireless receiver, the wireless receiver configured to receive packets from a first wireless transmitter/receiver that pages a second wireless transmitter/receiver to establish a communication between the first wireless transmitter/receiver and receive packets from the second wireless transmitter/receiver, the wireless receiver and the first wireless transmitter/receiver being movable to a plurality of different locations, the wireless receiver comprising:

• a receiver configured to receive a plurality of packets transmitted by the first wireless transmitter/receiver and transmitted by the second wireless transmitter/receiver at each of the plurality of different locations of the wireless receiver and for each establishment of a communication between the first wireless transmitter/receiver and the second wireless transmitter/receiver;
• a processing circuitry configured to:
• at each of the plurality of different locations of the wireless receiver:
• record the location of the wireless receiver and the first wireless transmitter/receiver;
• for each of the received plurality of packets:
• record reception times of packets transmitted by the first wireless transmitter/receiver and the second wireless transmitter/receiver;
• if a predefined amount of time has passed without receipt of a packet:
• calculate a time delay, td, based at least in part on the recorded reception time of each packet;
• and
• determine a location of the second wireless transmitter/receiver based on the calculated time delay;
• and
• determine a target location of the second wireless transmitter/receiver based on a plurality of the determined locations of the second wireless transmitter/receiver.

A wireless communication system movable to a plurality of different locations, the wireless communication system comprising:

• a first wireless transmitter/receiver configured to:
• initiate a paging sequence between the first wireless transmitter/receiver and a second wireless transmitter/receiver to establish a communication between the first wireless transmitter/receiver and the second wireless transmitter/receiver;
• and
• a wireless receiver, comprising:
• a receiver configured to receive a plurality of packets transmitted by the first wireless transmitter/receiver and transmitted by the second wireless transmitter/receiver at each of the plurality of different locations of the wireless receiver;
• a processing circuitry configured to:
• at each of the plurality of different locations of the wireless receiver:
• record the location of the wireless receiver and the first wireless transmitter/receiver;
• for each of the received plurality of packets:
• record reception times of packets transmitted by the first wireless transmitter/receiver and the second wireless transmitter/receiver;
• if a predefined amount of time has passed without receipt of a packet:
• calculate a time delay, td, based at least in part on the recorded reception time of each packet;
• and
• determine a location of the second wireless transmitter/receiver based on the calculated time delay;
• and
• determine a target location of the second wireless transmitter/receiver based on a plurality of the determined locations of the second wireless transmitter/receiver.
