The Way of the Warrior Wardriving Use your device and software to drive around and collect data about sites and locations of sites to compile a large site survey Warbiking Wardriving on a bike Single site survey Less complicated Usually done manually on foot Plot wireless cloud by hand Not as much need for GPS and logging Take photos of site
