May I suggest you to look into mesh networks? I am a huge fan of Reticulum. Using it feels like being a pioneer, the scene is very welcoming.

The pitch: it is network-agnostic. The same mesh network runs on the Internet or through LoRa radios or any other physical layer than allows the exchange of data packets. It scales from private networks to global meshes. It's the wild west. People are excited, and eager to grow further.
