Question about 10 mile wifi?

[jjh]

Hello:
I read about the activity at the last DEFCON in which a group of people established a 10 mile (I seem to remember 10, perhaps it was 2 miles) wifi link in the desert. I would appreciate any pointers to writeups as to how it was done, as well as a few of the participants. I've been experimenting a bit in this area and am interested in their approach. Thanks in advance.

btw... the latest long-distance link record is 125 miles, not 10.

I heard it was those 3 high school kids with several old sat dishes. Had their dad's van and fucked it up on the rough terrain but achieved the guiness record for 55 miles, then shut off the amps and won the unamplified contest too. Didn't really go into detail about their rig though....

I seen something on the Science Channel one night, about a expieremental town in some desert in the mid-west. They set there own WIFI expansion bridge up just useing old repeaters like the old packet radio ISPs' used in the 'yesteryears.'

It's actually possible to do it on near-by public use re-broadcating stations(mutch like cell sites,) of course it would be mildly un-stable and the FCC and local HAMs' would get pissed.

If I didn't have to work all the time I'd make a low cost solar powered re-broadcaster; I'd use parts from electric fence systems like ranchers use. You'de only need about 6 0.55v cells to run the board I'm thinking of which will work with 1.6Ghz to 4.5Ghz uplinks, then just have a low cost converter convert in back to the 2.8Ghz band 3/4 of the way.
