125-Mile WiFi Connection

Jason Striegel writes "Team iFibre Redwire smashed the WiFi distance record, successfully linking a distance of over 125 miles at this year's DefCon WiFi Shootout. They maintained a full 11Mbit unamplified connection for 3 hours using Z-com 300mw PCMCIA cards, surplus satellite dishes, Linux, and a great deal of hacker ingenuity. The best part: yesterday afternoon they said that they expect this rig would work at distances of over 300 miles. Here's additional team info, a couple pictures of one of their rigs, and some more technical details." I still wish I could find truly out-of-the-box Linux-friendly USB adapters, so I could get some tiny fraction of this distance, cheap.

Working at 300 miles?

How are they going to wrap their wifi signal around the Earth, assuming that they don't have their own satellite?

I don't think ionospheric propogation is going to work at wifi frequencies. And you won't get 11 Mb/s at 27Mhz.
