The present invention relates to a method and a system to establish a geographical relation between participating devices (p1, p2). A server (1) is holding a first list (111) representing participating devices, At least one searching device (s1, s2, s3) is performing a search for MAC-addresses belonging to other devices (d1, d2, d3, d4) within the reach of the searching device (s1, s2, 23), the searching device <s1, s2, s3) is sending a search result (r1 r2, r3) containing the MAC-addresses belonging to found devices to the server (1), and the server includes the searching device (s1, s2, s3) as a found device in the received search result r1', r2', r3'). The server (1) is forming a group (g1) of found devices comprising the search result (r1', r2', r3') received from each searching device (s1, s2, s3) and any previously received search result (r4'} where a match of MAC- address is found between at least one found device in respective search result, and the server (1) considers participating devices (p1, p2, p3, pn) to be geographically related to each other if the MAC-address of respective participating device is found in the same group (g1) of found devices. |
