A method for estimating a geographic location of a mobile station includes calculating an angular position of a mobile station to a base station based on first and second signal strength measurements and an angular position reference for the base station, the signal strength measurements from the mobile station for RF signals from first and second sector antennas of the base station. Another method includes calculating a radial distance of a mobile station from a base station serving the mobile station, determining a signal strength report from the mobile station includes a signal strength measurement for an RF signal from a first sector antenna of the base station, and identifying a geographic location of the mobile station based on intersection of a circle around the base station with a radius of the radial distance with a sub-sector geographic area in an RF coverage map for the first sector antenna.
