Abstract:
1. A method for generating a two-dimensional radio coverage map for an access point in a wireless environment comprising a plurality of physical levels including a first physical level and a second physical level, the method comprising: Generating, by one of a location assistance server, mobile station, or generation module, a first radio coverage map comprising a plurality of original points, each of the plurality of original points having a first predicted value, the first radio coverage map being located above the second physical level and at a first distance from the access point, the access point being located above the second physical level; selecting a target distance to place a plurality of map points corresponding to the two-dimensional radio coverage map between the first physical level and the second physical level and at the target distance from the access point; generating coordinates of the map points by magnifying the first radio coverage map using a ratio of the target distance to the first distance, each of the map points corresponding to one of the plurality of original points; computing an offset value representing an attenuation due to the target distance being different than the first distance; and generating for each of the map points a predicted received signal strength value by adding the offset value to the first predicted value of the corresponding one of the plurality of original points.
