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 20):
A method of determining a location of an electronic device, the method comprising:\n determining a first distance between a first electronic device having an unknown location and a second electronic device having a known location, determining the first distance comprising:\n generating a plurality of tones having a plurality of frequencies; \n modulating the tones with a carrier frequency to produce a first signal; \n transmitting the first signal between the first electronic device and the second electronic device; \n receiving the first signal; \n demodulating the first signal to extract the plurality of tones; \n extracting the phase of at least a portion of the plurality of tones; and \n determining phase differences between tones at different frequencies, each phase difference having a corresponding frequency difference; \n determining a second distance between the first electronic device having the unknown location and a third electronic device having a known location, determining the second distance comprising the same method as determining the first distance; determining a third distance between the first electronic device having the unknown location and a fourth electronic device having a known location, determining the third distance comprising the same method as determining the first distance; and calculating the first, second, and third distances based on the phase differences and corresponding frequency differences; and determining the location of said first electronic device based on said first, second, and third distances.
