SYSTEM AND METHOD FOR DETERMINING THE LOCATION OF A STATION IN A WIRELESS ENVIRONMENT
First Claim
1. A computer-implemented method of quantifying the shadow fading observed in a wireless environment having a plurality of wireless access points comprising:
- receiving location information relating to respective locations of the plurality of wireless access points at the wireless environment;
determining a distance between the pair of wireless access points based on the location information; and
determining a shadow fading factor based on the distance between the pair of wireless access points and based on received signal strength (RSS) information received from one of the wireless access points in the pair of wireless access points.

Abstract
A system for quantifying the shadow fading observed in a wireless environment having multiple wireless access points is also provided. A distance determination module is in signal communication with the wireless access points. The distance determination module determines a distance between a pair of the wireless access points based on location information that relates to the locations of the wireless access points at the wireless environment. A shadow fading determination module is also in signal communication with the wireless access points. The shadow fading determination module determines a shadow fading factor based on the distance between a pair of the wireless access points and based on RSS information received from one of the wireless access points in the pair of wireless access points.
