Wi-Fi Cheaters, Beware! DOMINO Will Get You
According to Imad Aad, a computer scientist at the Swiss Federal Institute of Technology in Lausanne, it's pretty easy to abuse Wi-Fi networks and to get a higher bandwidth than honest users. All you need is a recent and programmable Wi-Fi card and a Linux machine. You just have to change one line in the code of the Multiple Access Control (MAC) protocol to set the transfer rate at a high fixed value, and you're done. New Scientist has more details in "Greedy hackers can hog Wi-Fi bandwidth."
But beware, if the carriers catch you, they'll throw you out of the network and maybe even fine you. And their detective work to identify the cheaters can be easily done with Aad's tool, DOMINO, which claims to detect hackers in fractions of a second. My advice: don't cheat. More details and references are available in this overview.
