It’s that time again (actually, it was that time again about ten days ago, but better late than never). Go check out the November installment of SeattleWireless TV. This month’s issue includes a definitive look at War Driving from Drew of wifimaps.com, a sneak peek at New Zealand’s Wi-Fi treasure hunt, and more.

For the terminally impatient, you can grab the mpeg via BitTorrent. Enjoy!

How do you like the show?

Alrighty, look. When I saw this earlier, they claimed 71.48 miles on 100mW Ciscos. Now, the site claims 82 miles using 1.5 Watt amps. And, of course, it isn’t in the WayBack machine yet.

Go to the site and draw your own conclusions. =)

I saw this on the HSMM list. Apparently, students at Weber State University have set a distance record for an unamplified Wi-Fi link. have made a nice long distance shot across the Great Salt Lake. They made the shot using DSS dishes adapted for 2.4GHz use (something like this one) and Cisco 350 cards (which use puny 100mW radios), along with 1.5Watt amps. They went just under 72 82? miles, straight across the Great Salt Lake. They are currently planning a 90 mile shot.

They just about tied with (beat?) the 72 mile HPWREN link in San Diego, although that shot used 1 Watt amplifiers. That edged out the 110km (68 mile) shot in Poland, which used large 27dBi dishes and 500mW amplifiers.

As far as I know, the longest ever recorded Wi-Fi shot is still the 310 km (192 mile) shot to a stratospheric balloon in Sweden. Of course to pull that off, they used 6 Watt amps, and as they were shooting up into the sky, the didn’t have to contend with trees, buildings, earth, and the millions of other objects that reflect and absorb microwaves along the Earth’s surface.

So, now that this blog is apparently completely useless and Slashdot has picked it up, let’s do this: Please link to any long distance shots you know of that are more impressive than those listed here. Bonus points for low power and home made antennas!

Do you know of any long distance (preferably permanent, unlicensed) 802.11 links not mentioned here?
