Chris Huchel will preset on the Art of Wardriving and GPS on Thursday Feb 2nd in D bldg at BTC. From Wiki Pedia:
Wardriving (also known as LAN Jacking) is searching for Wi-Fi wireless networks by moving vehicle. It involves using a car or truck and a Wi-Fi-equipped computer, such as a laptop or a PDA, to detect the networks.
Many wardrivers use GPS devices to measure the location of the network find and log it on a website. For better range, antennas are built or bought, and vary from omnidirectional to highly directional. Software for wardriving is freely available on the Internet.
