Wardriving is a wireless networking term that refers to the event when a person in a moving vehicle with a Wi-Fi equipped computer like a laptop or a personal digital assistant (PDA) roams around a given location to search for Wi-Fi wireless networks. This instance is comparable to the use of a radio scanner, or to DXing (distancing), which is when HAM radio operators tune in and identify distant radio signals or make two-way radio contact with distant stations
