check out ham radio WSPR for an indication of the sorts of things that can be done

WSPR is very different than LoRa. WSPR is usually used at HF, and has very low bandwidth. LoRa is used at UHF frequencies, and has very wide bandwidth, as it's a spread spectrum modulation scheme.

There's more differences but those are the ones relevant to this discussion.

Not super familiar with LoRa, can you explain what makes it properietary? Is it the protocol?
