> If you have the correct antennas and possibly amplifiers on both ends you can established a Wifi link over hundreds of miles (if you have line of sight). Basically, if you can see the other device you want to communicate with at building level with your eyes then it's not too difficult to establish a Wifi link with it using off the shelf parts.
Any resources you can share to do this?
- nonamenoslogan 6y agoI can't speak to hundreds of miles, but I built a Wifi bridge that went about 1.75 miles across a cow pasture with center-pivot sprinklers using a pair of WRT-54G routers, DD-WRT, and some yagi/panel antennas from Amazon about 10 years ago. Total price was under $300 and speeds of 11mb were all we went for as it was just feeding a PC for browsing and time-card punches in a shop across the pasture from the office. It ran happily for nearly 6 years before being replaced with a packaged kit of antennas and POE injectors that advertised 54mb over 2-3 miles seamlessly for around the same price. If you had a pile of old 802.11b gear and the time and gumption, I'd think you could build something like this for sub-$50 at this point.
