Im planning to install a wireless network in my home to connects several computers ,i live in the city and have seen several wardriving websites which people gather maps of access points .

My question is this what equipment do they use to scan the networks do they use an adapter like WLAN network adapter or do they use pc cards that connect to an antenna ,do they also use GPS and how does this connect to there computer .

I find the art of war driving very interesting does anyone else think so or do they think it should be made illegal ?
