Patent ID: 7479889

Claim:
A fob for use with a cellular network and a global positioning system, said fob comprising: a cellular network transceiver for establishing a telecommunications link with the cellular network; a global positioning system receiver for generating an output of GPS location coordinates of said global positioning system; an independent radio frequency tracking beacon transmitter actuable for transmitting ID/data radio frequency signals, said independent radio frequency tracking beacon transmitter being independent from said cellular network transceiver, and said ID/data radio frequency signals having an identification code for identifying said independent radio frequency tracking beacon transmitter; and a protocol processor for electrically controlling said global positioning system, receiver, said cellular network transceiver and said independent radio frequency tracking beacon transmitter, and said protocol processor sending control signals to said independent radio frequency tracking beacon transmitter to cause said independent radio frequency tracking beacon transmitter to transmit ID/data radio frequency signals for detection by one or more tracking unit(s).
