Well, Reticulum is built on top of Meshtastic, which is built on top of LoRa. So Reticulum won't solve any range issues.

I know it can use 801.11 and Ethernet, but thise are way shorter range than LoRa.

Reticulm is cool, and it does have its place, but it's not very interesting without Meshtastic. It is Meshtastic that is the critical component for getting long range comms without the internet.
