Abstract: A method for generating a radio coverage map. A two-dimensional radio coverage map located between a first physical level and a second physical level is generated. The access point is located above the second physical level. The two-dimensional radio coverage map is located at a distance from the access point and comprises a plurality of map points, where the map points have a predicted received signal strength value. A projection window is determined. A projected area on the two-dimensional radio coverage map is determined by computing a geometrical projection from the access point through the projection window onto the two-dimensional radio coverage map. A plurality of first points in a first area on the two-dimensional radio coverage map is identified. The first area is outside the projected area. The predicted received signal strength value of each of the first points is reduced by a value equal to the signal attenuation caused by the second physical level.
