Abstract: Systems, apparatus, and methods for estimating the location of a wireless device include determining the location estimate based on accessible access points and without using a received signal strength indicator. In some embodiments, the location estimate is determined based on a center of mass of the accessible access points, a closest accessible access point, a center of mass of N access points, an average angle of the accessible access points, or a Parzen density of accessible access point distributions.
