Over at Linux Weekly News is a quick howto article on building Wifi detection networks using Raspberry Pi..
Years ago, I worked for an automotive IT provider, and occasionally we went out to the plants to search for rogue Wireless Access Points (WAPs). A rogue WAP is one that the company hasn't approved to be there. So if someone were to go and buy a wireless router, and plug it in to the network, that would be a rogue WAP. A rogue WAP also could be someone using a cell phone or MiFi as a Wi-Fi hotspot.
One thing I always wanted was a passive real-time wireless sensor network to watch for changes in Wi-Fi. A passive system, like Kismet and Airodump-NG, collects all the packets in the radio frequency (RF) that the card can detect and displays them. This finds hidden WAPs too, by looking at the clients talking to them.
The article describes how to set up a network of Raspberry Pis as Kismet drones, and using the information collected to triangulate the location of a rogue WAP.

When I was a wee lad, my friend told me that God cried and the Devil laughed whenever I made fun of retarded kids.
Satan: Ha Ha HAAAAAAAAA!
