Patent ID: 8428550

Claim:
A method of determining a location of a wireless mobile device with respect to an interconnected network of wireless transmission waveguides, the method comprising: receiving a wireless signal transmitted from a wireless mobile device at each of a first wireless probe at a first location within the interconnected network, a second wireless probe at a second location within the interconnected network, and a third wireless probe at a third location within the interconnected network; in the network, determining a first propagation delay of the wireless signal transmitted from the wireless mobile device to the first wireless probe, wherein the wireless signal enters the interconnected network through a first opening in a first wireless waveguide that is part of the interconnected network, and thereafter propagates to the first wireless probe along a first path within the interconnected network; in the network, determining a second propagation delay of the wireless signal transmitted from the wireless mobile device to the second wireless probe, wherein the wireless signal enters the interconnected network through a second opening in a second wireless waveguide that is part of the interconnected network, and thereafter propagates to the wireless second probe along a second path within the interconnected network; in the network, determining a third propagation delay of the wireless signal transmitted from the wireless mobile device to the third wireless probe, wherein the wireless signal enters the interconnected network through a third opening in a third wireless waveguide that is part of the interconnected network, and thereafter propagates to the third wireless probe along a third path within the interconnected network; and in the network, determining the location of the wireless mobile device with respect to the first, second, and third wireless probes using the first, second, and third propagation delays.
