15-Mile Wi-Fi Shot At 4 Mbps Up and Down

DarnComputers writes "5G Wireless (FGWC) announced that it has documented a long distance Wi-Fi shot of 15 miles at a throughput of 4Mbps upload and download speed. The shot was completed this last weekend, in a competitive Wi-Fi shootout at the Defcon convention in Las Vegas, Nev. There were many participants with both commercial-grade and homemade entries in a variety of categories at Defcon's first annual Wi-Fi shootout.http://home.earthlink.net/~wifi-shootout/"

Cardboard and tinfoil antennas

[yppiz]

I built a copy of the cardboard antenna that the winning team used at the core of their mongo-horn. It turns out that the design is quite robust (that is, even I can make it) and with just the amount of cardboard you'd get from two standard 16"x16" boxes, it's possible to make a 16db gain directional antenna.

What 16db means in terms of wireless use is than instead of picking up 4 access points from a rooftop using Netstumbler, I saw 40 different access points, including the BAWRN public node over eight miles away (with clear line of sight but an enormous amount of clutter in the fresnel zone).

I used this design from Seattlewireless.net

I strongly recommended trying this as a project. It's easy and pretty cool.

Wireless Homebrew Website

Here is a website for homebrew/amateur radio related wireless experimenting. It covers the construction of homebrew amplifiers, antennas, receiving converters, etc. They also have path analysis and line-of-sight analysis CGI utilities.

Dunno if this will help you, but Linksys has a signal booster for your Linksys wireless device. Pop the antennas off the existing one, pop them on the booster, connect the booster to the access point, and (according to Linksys), you're good to go.
