Method and system for determining a location of wireless device

摘要

A system for (a) determining a first direction from a first device toward a second device based on a first set of WiFi® wireless signals received by at least one antenna of the first device from the second device, (b) determining a second direction from a third device toward the second device based on a second set of WiFi® wireless signals received by at least one antenna of the third device from the second device, and (c) based at least on a first location of the first device, the first direction from the first device toward the second device, a second location of the third device, and the second direction from the third device toward the second device: determining a third location of the second device.

主权项

1. A computer implemented method, comprising:
receiving first information at a network device, wherein the first information corresponds to a client device, and wherein the first information is associated with a first wireless signal received at a first access point; identifying a first direction using the first information to determine a first projection in the first direction from the first access point; receiving second information, wherein the second information corresponds to the client device, and wherein the second information is associated with a second wireless signal received at a second access point; identifying a second direction using the second information to determine a second projection in the second direction from the second access point; identifying intersection data based on the first direction and the second direction to determine an intersection point between the first projection and the second projection; and determining a location of the client device using the intersection data by determination of a relative position offset and reference of the relative position offset to known coordinates.
