Here's a completely random section of Texas that I found on Google Maps. Have fun making a mesh network out of the houses there. You might have more fun playing "I Spy", with the aim to find the houses. https://www.google.com/maps/place/Texas/@32.4826637,-98.4527...
Ok, fair point, but you know, some wifi chips have range far larger than advertised. Especially in flat non crowded area where you can have line-of-sight and less noise. Some youtube video show packets traveling a few miles on a stupid esp8266 chip. I don't know how sparse texas is, but I'm sure you can find a nice % of houses whose distance to each others is lower than 1mile.
I had about a decade of wireless ISP in a neighborhood. It was ok, but speeds suffered as the number of users increased. BTW, this city of 30,000 doesn't have cable and it didn't really get started until 1999. Cable companies didn't want to build it out.
Now I'm in the middle of nowhere and there isn't a WISP to be found. Houses are to far apart and there are too many trees. Noise? I don't have any of that, but line of sight doesn't exist.
I think getting a workable mesh going anywhere would be tough, there is always something.
