Other people could answer this much, much better than me, but as I understand, Reticulum (meshtash more specifically and LoRa even more specifically) uses radio waves. Like a TV antenna, the height of the antenna matters, line of sight, all that stuff. But, 2-5 km seems a good number, up to 10 km if it's hyped up. Less if in a city or trees or hills etc.

That is for one unit. Of course, if it meshes with another, say 3 km away, then that device could link to another and so on. I think, theoretically, there is no range limit.

As I understand, bitchat's bluetooth on your phone can pick up another phone like up to 10m. The 300m is if you leap-frog over other phone's/node/connections. To me, that requires a lot of people/nodes in one place...hence why I say a convention or concert would be great for this. But in real life, I don't see that happening too much. Maybe Times Square on New Year's Eve! :)

I asked Grok for an ascii graph comparison:

Range (feet) 10,000 | | 9,000 | | 8,000 | | 7,000 | | 6,562 |====================== LoRa (Meshtastic, ~2 km) | 6,000 | | 5,000 | | 4,000 | | 3,000 | | 2,000 | | 1,000 |= BitChat (Bluetooth mesh, ~300 m / 984 ft) | 0 |_________________________________________________________________| BitChat LoRa

Somebody correct me on this if I'm wrong, which I very likely could be.
