Abstract
A method for generating an indoor environment model of a building. The method comprises forming a transmitter location model for defining positions of transmitters in said building using gathered information for establishing transmitter locations. The method further comprises receiving signal strength indicative measurements determined for a number of transmitters using at least one electronic communications device wherein the signal strength indicative measurements are based on a signal which has varying signal propagation characteristics in the indoor environment The signal strength indicative measurements are acquired from a number of known locations in the building, identifying discrepancies of signal transmittance in said indoor environment based on said signal strength indicative measurements in relation to said transmitter location model. The method further comprises determining locations of signal hindering elements causing said discrepancies and generating said indoor environment model including transmitter locations and said signal hindering elements.
