1. A method of low power estimation of a location of a wireless device based on accessible access points within a perimeter, comprising the steps of:
- determining a location estimate of the wireless device based on one of 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, and a Parzen density of an accessible access point distribution.

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.
