New Scientist: Wi-Fi networks can be jammed from PDAs

5/17/04 by Jeff Hecht
"Wi-Fi networks can be jammed using nothing more sophisticated than a PDA and an off-the-shelf wireless networking card, the Australian Computer Emergency Response Team has warned.
Wi-Fi networks are becoming common in workplaces and elsewhere and it was known that they are vulnerable to jamming. It was thought that this would require the use of large, powerful and expensive equipment, but students at the Queensland University of Technology have now proved this wrong."
This shouldn't come as too much of a surprise, but it is good to be reminded. The article goes on to mention that this susceptibility to jamming is due to the protocol and that smart systems can detect and deny access to jammers.
