LoRA will always have spotty coverage. There might be a lot of spots all over the place, but they're still just little spots. For short messages, you need much lower frequency. Then you can cover entire cities from one or two sites. The lowest-frequency LoRA transmitters are still UHF, and they can't be used from towers or hilltops due to HAAT restrictions: https://en.m.wikipedia.org/wiki/Height_above_average_terrain https://en.m.wikipedia.org/wiki/Height_above_average_terrain You really want something VHF or below. Like a chunk of the former analog TV bands. A really really tiny sliver is enough. LoRA is a horrifically bandwidth-inefficient protocol. It craps on a gigantic swath of frequencies in order to send a few bits of data. They call it a "chirp", not a "crap". The only reason anybody gets away with such a wasteful modulation scheme is that it happens in the garbage band.
