My parents live on a farm about 11 km outside town (as the crow flies), in a valley where there's no line of sight to town. So they don't even have cell phone reception. About 2 km from their house (and about 12 km from town) there's a mountain from where you can see the town, and their house. I want to set up a wifi bridge on the mountain so they can get internet via an ADSL line in town. I'm guessing I need the following:
- Wifi router & directional antenna in town
- Router in bridge mode, with antenna that that sees both of end points (end points are separated by about 80 degrees). Solar panel & battery to give power to the bridge router
- router and directional antenna at their house on the farm
Any advice on how to do this the cheapest way?
