an ARES group in a neighboring county set up an AREDN network. They said it worked very well, with two caveats.

First was a jurisdiction issue. They couldn’t send climbers up to replace or repair equipment on their own, they had to wait for another entity to do it, this lead to things going unrepaired for a long time, which leads to…

Second, WISP equipment, even outdoor-rated stuff, isn’t as weatherproof as one would hope. Where I live (gulf coast US) we get a lot of wind and rain, so things broke down often. Combine this with the inability to replace and repair equipment as needed and you get a perpetually flaky network. I think it’s no accident that the most active AREDN mesh is in SoCal where the weather is perpetually clement.

This is all second hand, of course, though I can vouch for the WISP gear not being exactly Ragnarok proof. It seems when it worked, it worked very well, but it often didn’t work for the reasons above. If you can locate equipment in places you have access to, I think it’ll be fine.
