Hello..
i was wondering.. how can you find a specific client (cell phone, or notebook) in an area if you don't know previously the mac address?.
are there any modules that allows you to "take a snapshot" of currently connected mac addresses? so, you can go to a next please following that person and if there is a match of the mac address there is a chance that that mobile is from the person you are looking for (excluding yourself of course);
i guess this will also by a good practice to see "over your shoulder" if someone it's following you phisically
