A method for estimating a geographic location of a mobile station within a coverage area of a wireless network includes: determining a radial distance of the mobile station from a serving base station based on a round trip measurement and calculating an angular position of the mobile station in relation to the radial distance based on a first signal strength measurement, a second signal strength measurement, and an angular position reference that extends outward from the serving base station. The signal strength measurements representative of power characteristics of RF signals received by the mobile station from first and second sector antennas of the serving base station. An apparatus associated therewith includes a distance module to perform the determining and an angular position module to perform the calculating. The apparatus may be implemented in a base station, a geo-location service node, a network management node, or other communication nodes.
