METHOD FOR MAPPING WI-FI SIGNATURES BY MEANS OF THE BLIND COLLECTION OF RSS MEASUREMENTS

摘要

The present invention relates to a method for mapping Wi-Fi signatures in a given geographical area. A user, provided with a receiver, sequentially collects (110) Wi-Fi signal strength measurements while moving along the path thereof, each measurement consisting of a vector of the RSS levels received from the various Wi-Fi access points. A graph that is representative of the path is determined (120) from the sequence of measurements. Using a geometric model of the area, a topographical characterization of the path is carried out (130) on the basis of the previously obtained representative graph. The positions of the various measurements of the sequence are provided by the topographical characterization and stored (140) with said measurements in a database.
