1. A computer implemented method comprising:receiving environment information comprising at least planning area definitions, information on propagation obstacles in the planning area, and access point installation height;
dividing the planning area into plurality of location topological cells;
calculating for each location topological cell a plurality of metrics of different types, wherein the plurality of metrics provides values for different properties of a radio signal coverage pattern, one metric providing one or more values for a single property;
converting each metric to a metric score;
calculating for each location topological cell a location score from a plurality of metric scores corresponding the plurality of calculated metrics for the location topological cells wherein a location score is a value depicting the quality of a corresponding location topological cell as an installation point of an access point with the access point installation height; and
storing at least temporarily the location scores associated with corresponding location topological cell for a computerized wireless network planning tool to provide information for determining of final locations of access points in a wireless network that is being planned.
