I need communications somewhere with no cell signal
Separate two questions that get muddled: reaching the outside world, and talking across your own property. The second one is cheap, independent, and the one most people never solve.
What actually works
$25–45 a node, miles of range, works with every other service down, and needs no subscription or tower. **One node on the highest point you can reach usually covers a whole farm.** Height beats power, every time.
One buried conduit run beats any amount of wireless cleverness — and pull a string with the cable so the next one is easy. Mount access points **inside** metal buildings; steel is a wall.
Both work, both are a monthly bill, and both go down. Useful, but don't build anything that *has* to have them — which is the whole argument for keeping notifications on your own network.
Unglamorous and immediately useful for two people working opposite ends of a property. No infrastructure at all.
