Geolocation determination with power fingerprinting

Abstract:

A method for deriving geolocation of a mobile device within a coverage area of a cellular communication network includes receiving pathloss data and measurement data associated with a plurality of individual sectors within a plurality of individual cells of the cellular communication network. Each of the plurality of individual sectors includes a plurality of geographic bins. Reception power measurements are determined for each of the plurality of geographic bins. A plurality of maps is generated for each of the plurality of individual sectors based on at least one characteristic included in the received pathloss data or measurement data or based on the determined one or more reception power measurements. Geolocation of the mobile device is determined based on the generated plurality of maps.
