Abstract

A method for generating a two-dimensional radio coverage map comprising a plurality of physical levels including a first physical level and a second physical level. The access point is located above the second physical level. A first radio coverage map comprising original points located at a first distance from the access point is generated. Each of the original points has a first predicted value. A distance is selected to place the two-dimensional radio coverage map at the target distance from the access point. Coordinates of map points of the two-dimensional radio coverage map are generated. Each of the map points corresponds to one of the original points. An offset value representing an attenuation due to the target distance being different than the first distance is computed. For each of the map points, a predicted received signal strength value is generated by adding the offset value to the first predicted value of the corresponding one of the original points.
