Method, system and non-transitory computer-readable medium for the unambiguous identification of non-associated Wi-Fi devices

A system for the unambiguous identification of non-associated Wi-Fi devices, the system comprising at least one access point, wherein each access point comprises:

• a Wi-Fi interface;
• a processing unit configured to:
• upon receiving a probe request from a Wi-Fi device not associated to the access point, send a probe response addressed to the non-associated Wi-Fi device, wherein the probe response comprises a Hotspot 2.0 Indication element including a ANQP (Access Network Query Protocol) Domain ID field with a determined value;
• receive an action frame sent by the non-associated Wi-Fi device in response to the Hotspot 2.0 Indication element of the probe response;
• obtain a static MAC address of the non-associated Wi-Fi device from the source address of the received action frame;
• and
• identify the non-associated Wi-Fi device based on the obtained static MAC address,
• wherein the processing unit of each access point is configured to modify the combined value of the ANQP Domain ID field and the SSID field of the probe response each time the probe response is sent again to the same non-associated Wi-Fi device.

A method for the unambiguous identification of non-associated Wi-Fi devices, the method comprising:

• upon receiving, by an access point, a probe request from a Wi-Fi device not associated to the access point, sending a probe response addressed to the non-associated Wi-Fi device, wherein the probe response comprises a Hotspot 2.0 Indication element including a ANQP Domain ID field with a determined value;
• receiving, by the access point, an action frame sent by the non-associated Wi-Fi device in response to the Hotspot 2.0 Indication element of the probe response;
• obtaining a static MAC address of the non-associated Wi-Fi device from the source address of the received action frame;
• and
• identifying the non-associated Wi-Fi device based on the obtained static MAC address,
• periodically modifying, by the access point, the value of the ANQP Domain ID field to be used in the probe response, and further comprising modifying the SSID field to be used in the probe response when a determined number of values have been used for the ANQP Domain ID field.
