—We present a method to estimate the coverage areas of transmitters, and a method to use a database of such coverage areas for personal positioning. The coverage areas are modelled as ellipsoids, and their location and shape parameters are computed from reception samples (fingerprints) using Bayesian estimation. The position is computed as a weighted(More)
A variety of commercial location based services have appeared during recent years. Location awareness is becoming more important also in environments where satellite-based positioning are not available, such as urban areas and indoors. In this work, a method to estimate the coverage area of a wireless communication node is presented. Also a method to use a(More)
