Does this exist already? Meshtastic doesn't do IP.

Sure does - MeshCore for example:

https://meshcore-analyzer.eu/#map

Quite active here in Czech Republic for example.

As for the IP protocol - maybe its too much overhead for this use case ?

MeshCore uses PKI and public key prefixes as addresses & for routing/repeating.

Did not know this, thanks for sharing.

Or Reticulum. Nomadnet over lora works pretty well.

Yeah, MeshCore works impressively well but definitely there is a huge space for many nice improvements and novel use cases. Only time will tell if they will come MeshCore, the other LoRa mesh projects or something completely new. :)

Who owns the spectrum?

In Europe it is using the 868 MHz ISM band with some duty cycle rules (maximu of 10% of every hour can be used for broadcasting).

In the US apparently 433 MHz is used instead.

These bands are trivial to jam should any adversary want.

Sure, but there are some issues with that:

- LoRa has actually quite a long range if done right (tens of km, upt to hundred+) so you would have to jam all that.

- This kind of jamming would be actually illegal, so you would have to make it legal first/tollerate it & expend non-trivial respurces to jam tiny repeaters from Aliexpress on random trees.

- The 868 MHz hand is actually used by a lot of IoT stuff like sensor networks, water/gas/electricity meter monitoring, some alarm systems - so if you did effectively jam the band, those things would break as well.

- Also if things went as far as active jamming being used, things might be heated up enough that whoever is running the mesh won't be playing by the reules as well - like, using a different, notmally ilegal fregvency or even triangulate and attack the jammers.

We've had enough people around here _accidentally_ jam the 868 MHz and each time it took months to figure out what was going on before meshtastic worked again..
