Method and System for Estimating Range of Mobile Device to Wireless Installation
First Claim
1. A method of estimating the position of a mobile device, the method comprising:
- the mobile device receiving signals transmitted by a plurality of fixed-position wireless communication stations in range of the mobile device;
designating one of the plurality of fixed-position wireless communication stations from which signals are received by the mobile device as a serving station;
retrieving location information for said serving station and at least one other neighboring station of the plurality of fixed-position wireless communication stations from which signals are received by the mobile device;
for each of the at least one other neighboring stations, determining a corresponding distance between the serving station and said neighboring station based on the location information; and
estimating a position of the mobile device based on the location information for the serving station and said neighboring stations and further based on the distances between the serving station and said neighboring stations.

Abstract
A method of and system for estimating the range of a mobile device to a wireless installation is disclosed. A method of estimating the position of a mobile device includes receiving signals transmitted by fixed-position wireless communication stations in range of a mobile device. One of the wireless communication stations from which signals are received by the mobile device is designated as a serving station and location information is retrieved for said serving station and at least one other neighboring station from which signals are received. For each of the at least one other neighboring stations, a corresponding distance between the serving station and said neighboring station is determined based on the location information. A position of the mobile device is estimated based on the location information for the serving station and said neighboring stations and further based on the distances between the serving station and said neighboring stations.
