Wardriving is the art of driving around scanning for WiFi networks. This powerful kit can be mounted on your car window on the passengers side and you can use a stumbler in addition to a GPS receiver to log coordinates. You could probably get a cheaper GPS logger as well as a different model. I prefer the Holux 1200E. Even Tom Tom has a Bluetooth GPS logger for around $30 USD. If you have a smartphone with GPS capabilities you could do without a standalone logger. This is a serious kit for serious people and likely to be illegal in some countries. We recommend that you use BackTrack 5R2, latest compat-wireless drivers, increase TX power beyond your regulatory domain and install it onto a hard drive or virtual machine (VM) environment. I will add other sources and suppliers when I have a chance.
