The "100x bandwidth" claim needs to be substantiated. There are some significant regulatory issues with the current popular mesh network protocols in the USA, namely that neither MeshCore or Meshtastic are compliant with the actual FCC regulations. 100x bandwidth because you're breaking the rules isn't the same as 100x bandwidth legally. Here is the issue discussing this in the MeshCore repository: https://github.com…

Seems more of an issue of outdated and de facto unenforceable regulations than an issue with the protocol.

Correct. The LoRa configurations mentioned which offer 100× the speed of Meshtastic/Core operate at 800 kHz and 1.6 MHz bandwidth, which are permitted by the FCC in 15.247. As far as I know there's not actually anything particular to 2.4 GHz allowing higher throughput for LoRa than that the corresponding Semtech chip happens to support wider bandwidths. (I.e. no legal barrier.) The tradeoff is less range due to lower…

At least in Europe the 868 Band is is in contrast to 2.4 allowed only for low duty cycle applications that do not actually occupy the channel for more than 1% afaik (given space multiplexing). I also remember also that the free to us band was quite narrow by design (we built sensor nodes bit banging a PHY transceiver that were in the grey area of unenforced rules, 20 years ago .l)

Nobody uses the 1% bands afaik, there are 10% duty cycle bands.

The issue you linked to is about MeshCore using channels that are too narrow . A mesh system claiming to offer 100x bandwidth is probably not violating regulations in that particular way.

i am just reading "its not allowed" "rules are being broken" "not premitted" lol. how should you invoate and break free from the current ISP model, if everythig is not premitted?

I think I can give it a pretty nice use: distributed ring signature over long distances. We can distribute people over different regions for redundancy and form long distance encryption channel to deliver a signature of some data, and use it to make consensus with enough provenance. Kind of like e-voting but with stronger assumptions.

By using a long distance communication device this eliminates the proximity strike problem. This could easily be extended to say like distributing the voting rights to different generals at different regions, and given that the device is genuine and not modified, can be a hardware voting key to say like launch the nuke in secrecy or not.

Whether adversarials can use the radio signals that it emits to triangulate you and thus track you is another story, though.

There are more rules being broken. For example, overusing the frequency which effectively prevents others users from sending messages. In the end, won't be used.

In the EU, the duty cycle limit is like 10% per hour. North America doesn't have that restriction...

Ah, thanks. Had the idea the duty cycle restriction would be common.

Thank you for the update.

That would violate the First Amendment. /s

"regulatory issues with the current popular mesh network protocols in the USA"

There are other countries in the world.

And there are also places where there is no electromagnetic policies (think about over the oceans).

> de facto unenforceable regulations

I guess you have never encountered the anger and wrath of a retiree who's into ham radio and has the regulatory office on speed dial.
