Abstract
A method and apparatus for wireless location tracking by a wireless device. In one embodiment of the invention, the wireless device has logic to determine the information of a plurality of specific location points and to determine the location of the wireless device based on the information of the plurality of specific location points. The specific location points are selected from a target area where the wireless device is located. By selecting the specific location points in the target area, it allows hidden Access Points (APs) or Base Stations (BSs) to be detected and measured and it increases the accuracy of the tracking of the wireless device.
