Patent attributes
The disclosed embodiments estimate a location of a first wireless device based on signals received from the wireless device from two other wireless devices. To combine estimates of the two wireless devices, the two wireless devices share a definition of a plurality of geographic regions. A first set of expected phase differences for the plurality of regions are determined for a first of the two wireless devices, and a second set of expected phase differences for the plurality of regions are determined for a second of the two wireless devices. Based on these two sets of expected phase differences, each of the two devices estimate a position of the first wireless device.
