Most WiFi enabled devices broadcast their Mac address when probing for networks to join in the vicinity. By placing your own WiFi device in promiscuous/listening mode and utilizing a tool like Aircrack-ng, you can see and record all broadcast traffic enabling you to see if a device with a specific MAC address comes within earshot of your listening device. ...

I think the comment of @Luc is as giving a direction that merits to be expanded here into an answer. Consider the following. The hardware to have a 0.5lb mobile device run at 480p resolution etc is quite recent. Consequently it is only recently that those mobile systems you mention in your question exists. Desktop system which have been able to use ...

You can filter for them using the following syntax: wlan.fc.type_subtype == 0x04 These are managment frames and are basically frames sent from your client to find out which wireless networks / AP are ...

The closest thing to a 'hello' packet concept in a smart phone, which mostly use TCP/IP, will probably be a DHCP-DISCOVER broadcast and then subsequent ARP requests, presuming it is active on the network. Most smart phones will probably respond to ping, too, so presuming you have control over DHCP on the network, once you know its IP address, send pings to ...

GSM uses three different security algorithms - A3, A5, and A8. The A3 algorithm is used to authenticate the mobile device, the A5 algorithm to encrypt the data transmitted, and the A8 algorithm is used to generate the session key. Hence, I believe you are interested in the A8 algorithm which deviates the session keys through a challenge and response ...
