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:
- identifying, by the mobile device, a plurality of fixed-position wireless communication stations in range of the mobile device based on the mobile device receiving signals transmitted by the plurality of fixed-position wireless communication stations;
designating one of the plurality of fixed-position wireless communication stations from which signals are received by the mobile device as a designated reference station;
retrieving location information for said designated reference station and one or more other neighboring stations of the plurality of fixed-position wireless communication stations from which signals are received by the mobile device;
for each of the neighboring stations, determining a corresponding distance between the designated reference station and said neighboring station based on the location information;
applying corresponding weighting factors to the location information of the designated reference station and of the neighboring stations, wherein the weighting factors corresponding to the neighboring stations are based on the distance between the designated reference station and the neighboring stations; and
estimating a position of the mobile device based on the location information for the designated reference station and the neighboring stations weighted according to the applied weighting factors and the estimated distance from the mobile device to the designated reference station.

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.

33. A method of estimating the position of a mobile device, the method comprising:
-
identifying, by the mobile device, a plurality of fixed-position wireless communication stations in range of the mobile device based on the mobile device receiving signals transmitted by the plurality of fixed-position wireless communication stations; designating one of the plurality of fixed-position wireless communication stations that is closest to the mobile device as a designated reference station; retrieving location information for the designated reference station and for one or more other neighboring stations of the plurality of fixed-position wireless communication stations; for each of the one or more neighboring stations, determining a corresponding distance between the designated reference station and the respective neighboring station; assigning corresponding weighting factors to the location information of the one or more neighboring stations, wherein each weighting factor is based on the distance between the designated reference station and the respective neighboring station; and estimating a position of the mobile device at least in part based on the location information for the one or more neighboring stations and the assigned weighting factors. - View Dependent Claims (34)
