How can I know how many people in the area of beacon?
If I want to count people that in a specific beacon area, I have to check probe requests or probe responses? Then, how to filter out the specific SSID's probe requests/responses? I have to make that information(without other SSIDs') to a pcap file.
I might be passing by with my wifi settings off. So wireshark will never see anything.
And somehow I get the feeling we are asked in doing your homework for you.
