This seems like a great technology to build resiliency and redundancy in a community, especially for places where cell service is spotty, or in the odd event where normal lines of communication are blocked.

The LoRa boards can be easily powered with a small solar panel for continuous use, and if put in a high enough place with a good antenna, they can have a surprisingly long range!

In addition to being genuinely useful, they also seem like they'd be a lot of fun to experiment and play around with, printing cool 3D cases for them, or designing a better antenna or repeater setup.

If and of you already have experience with LoRa, I'd be interested to hear your thoughts! :D

LoRa is, as far as I know, legal to use in most countries without a license, and do not broadcast on HAM frequencies.

ah, that's great. To complement on the discussion, I found this site with a relationship of the used band and the corresponding legislation https://www.loraantenna.com/lorawan-frequency-plans-by-country-region/

True, but different frequencies per region. So if you used hardware in the wrong region it could be illegal. Still, in the US and EU at least, it is a public open band.
