RE: Wardriving with Yagi Antennas



Here is a link to the "ultimate war driver" although not used for that purpose this Amateur Radio mobile communications center is more than capable of getting a signal farther than 10 miles, a lot farther. Ham radio operators are not constrained to the "commercial power limits" in parts of the "WiFi" spectrum. I think the power limit may be 5 Watts ERP or perhaps 50.

For a brief history of wireless networking see http://www.cfs.sunysb.edu/Stu/pnoboa/ (and web search it!) "This network was called the ALOHANET and is considered to be the world first wireless network."

Amateur radio experimenters have been instrumental in the development of many commonly used communications modes, wireless digital and networking in particular.
