Did you know?

There’s a 237 mile WiFi link in Venezuela?
…and that this point-to-point non-amplified link achieves 3 Mbps?
…and uses the standard IEEE 802.11 22 MHz on channel 1?

They used Linksys WRT54G wireless routers, one on each end. Both run Linux-based firmware (OpenWrt and DD-WRT). These modified routers, provided by Berkeley University, were connected to 9 foot recycled parabolic dish antennas once used for satellite service. This setup achieved a distance record linking at almost 400 km back in 2007. They used the standard 100 milliwatt transmit power with a 30 dBi gain.

Why Wifi, why not WiMAX?

WiFi works, it’s proven, cheap, and readily available. And that’s what matters most because in the end, connecting remote areas via WiMAX or other brand new technologies isn’t going to help the people on the ground that really need these connections the most.

Slashdot is pulling old info and reporting the old link range of only 192 miles. Time to update that wikipedia page.
