Claim 9:
10. A system for detecting stations in wireless local area networks, the system comprising at least one access point of one or more wireless local area networks, wherein each access point of the system is configured to:
upon transmission of an association response to a station, send a radio measurement request addressed to the station, wherein the radio measurement request includes a command to perform active scanning of a specific SSID, wherein the SSID field of the radio measurement request comprises a unique identifier univocally associated with a persistent MAC address of the station, wherein the unique identifier comprises a common identifier as a first sub-field;
upon reception of a probe request sent by the station, analyze the SSID field of the probe request and determine that the SSID field of the probe request comprises a unique identifier univocally associated with a persistent MAC address of the station when if the SSID field of the probe request contains a first sub-field that corresponds to the common identifier, and in that case:
obtain the persistent MAC address of the station from the unique identifier of the SSID field of the probe request, and
associate the source address of the probe request with the persistent MAC address of the station on a database of known stations;

detect stations within the coverage area of the access point based on the information stored on the database of known stations.
