I use a neighborhood network daily. Using it now as a matter of fact. We winter in a desert area in Southern AZ. There is a wi-fi node in a building about half a mile from me. It is nothing special except it has a directional antenna mounted on top of a one story building.

Most of the users (probably 50 or more) also use some sort of directional antenna. Some are 3/4 miles from the node. Works fine.

None of us have grid power, all solar. The node is on the grid.

We don't use it as a local network, although we could. Just wi-fi to the internet.
