1. A localization method of a mobile station (2) communicating with at least one central server (1) through a wireless network comprising a plurality of wireless radiofrequency transmitting access points (3), among which a first access point is chosen to perform the communication, comprising the steps of:

  • measuring the signal strengths received by said station from the plurality of access points;

    storing each measured strength with an address identifying the corresponding connected access point;

    comparing said stored strengths to values of a predetermined table of signal strength thresholds affected to access points, defining one or more event zones (EZ) each comprising one or more attenuation ranges of one or more access points; and

    considering the station as located in a given event zone if the measured strength corresponding to an access point defining that event zone is comprised in the attenuation range of that access point.
