Abstract
A method of localising an access point (B1, B2, B3) to a communication network; The method comprises the following steps: reconstruction of a trajectory (P1, P2, P3, P4) followed by a mobile device during a displacement during which it makes measurements of an indicator related to the distance separating it from the access point; determination of a localisation (T1, T2, T3) at which each of the measurements on the trajectory is made; calculation for each measurement of a difference between the distance separating a possible localisation of the access point from the location at which the measurement is made and a distance estimated from the measurement and a propagation model relating the indicator and the distance, and calculation of a localisation error from the calculated differences. The propagation model is updated at each evaluation of a possible localisation of the access point.
