Abstract:
Embodiments of the present invention include a method of determining a location of a mobile device. The method comprises transmitting a signal between a plurality of known locations and receiving signal at device of unknown location such as a mobile device. The signal may include multiple tones having different frequencies and resulting in sets of residual phase differences. The location of the mobile device may be determined using the known locations and the frequency and phase differences between the transmitted tones. In one embodiment, OFDM signals may be used between an access point and mobile device, for example, to determine the location of the mobile device.

Claim (Index 1):
A method of determining a location of an electronic device, the method comprising:\n transmitting one or more signals between a first electronic device at an unknown location and three or more electronic devices at three or more corresponding known locations, wherein the one or more signals each include a plurality of tones having different frequencies; determining at least one first phase difference between at least two tones having a first frequency difference in the one or more signals accumulated during transmission between the first electronic device and a first electronic device of said three or more electronic devices; determining at least one second phase difference between at least two tones having a second frequency difference in the one or more signals accumulated during transmission between the first electronic device and a second electronic device of said three or more electronic devices; determining at least one third phase difference between at least two tones having a third frequency difference in the one or more signals accumulated during transmission between the first electronic device and a third electronic device of said three or more electronic devices; and determining the location of said first electronic device using said first, second, and third phase differences and said first, second, and third frequency differences.
