Colin over at Sudhian has written a brilliant article on wireless networking and security limitations which currently face it. He talks about "wardriving", a fascinating new term of driving around populated areas in your car looking for open wireless networks and borrowing their high-speed Internet connection, or peaking into their network, if you are into that type of thing.
Hmm, now I have an overwhelming desire to grab my notebook, installed with wireless adapter and Net Stumbler, and hit the road - *evil grins*.
We only want to surf the net, check e-mail and maybe download some MP3s. I attained speeds of 180k on my 300mhz iBook from the wireless T1 network at Starbucks, a good speed for any connection. OK, so I wasn't in Starbucks, I was in the parking lot in my car. There is another advantage of wireless; you don't have to go into Starbucks.More information @ Sudhian Media
