Title:
SYSTEMS, APPARATUS, AND METHODS FOR LOCATION ESTIMATION OF A MOBILE DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/160455
Kind Code:
A3
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.
