Record Set at DefCon WiFi ShootoutBy Pedro HernandezAugust 2, 2005
While Defcon and Blackhat were buzzing with news that Cisco and ISS researcher Michael Lynn were embroiled in a security disclosure scandal that now involves the FBI, a group of techies set out to make a different kind of mark on the proceedings. During this year's Defcon WiFi Shootout, reigning champions Team iFiber Redwire trekked to the Las Vegas, Nevada desert area to test the limits of WiFi connectivity on July 30. The result was a successful, unamplified 11 Mbps connection over a distance of 124.9 miles for three hours between Las Vegas, Nevada and Utah Hill, Utah. Making 11,000 successful pings during that time, the group (then called Team P.A.D.) more than doubled their previous distance and set a new wireless world record. The record holders relied on more than just a pair of wireless laptops. The equipment required for the feat, according to the event website, included a "collection of homemade antennas, surplus 12 foot satellite dishes, home-welded support structures, scaffolds, ropes and computers". The business end of the setup included Z-Com XI-325HP+ PCMCIA 802.11b wireless card on both ends running on Ubuntu Hoary (Nevada side) and Debian Sarge (Utah side) OSes. Ping times averaged 10 milliseconds (ms), with variances ranging from 0.01 ms to 400 ms. iFiber Redwire reports that the they were able to establish a Virtual Network Computing (VNC) connection without dropping frames. Full technical details are available at the WiFi World Record site.
