Abstract
A method is provided that includes obtaining or holding available radio positioning support map information and geographic map information. An overlapping geographic area is covered by the radio positioning support map and the geographic map, which is dividable into a plurality of subareas. The method also includes determining, for each subarea of the plurality of subareas, a respective observed radio positioning support device density at least partially based on the radio positioning support map and a respective expected radio positioning support device density at least partially based on the geographic map. The method further includes evaluating, for each subarea of the plurality of subareas, a respective radio positioning performance in a respective subarea at least partially based on the respective observed radio positioning support device density and the respective expected radio positioning support device density. A corresponding apparatus and computer readable storage medium are also provided.
