Patent ID: 8519889

Claim:
A method comprising: for each a plurality of beaming angles, transmitting, at an access point, a plurality of non-identical wireless signals on a respective plurality of partially overlapping antenna beams of a multi-beam antenna pattern substantially simultaneously; receiving, at the access point, a signal from a wireless station indicating the beaming angle at which a ratio of a respective received signal strength property of at least two of the substantially simultaneously transmitted non-identical wireless signals transmitted on respective antenna beams of the multi-beam antenna pattern is substantially equal to a predetermined value; determining, based on the beaming angle indicated in the signal received from the wireless station, a bearing angle, wherein the bearing angle is determined relative to a reference point of the access point to the wireless station, the bearing angle indicating a geographic coordinate of a location of the wireless station; determining a radial distance between the wireless station and the reference point of the access point, wherein the radial distance is determined based on at least one of a signal strength measurement and a timing advance calculation; and determining the location of the wireless station based on the determined bearing angle and the determined radial distance.
