This tech would be great if we had high power nodes all across the globe. But we do not. Maybe a cool idea could be encrypted data over FM radio. The radio stations already exist and are a dying business. Nonprofits could buy up radio stations and rebroadcast data broadly and only those with the encryption keys could decrypt. Cut the ISP out entirely. Like the difference between a local call and a long distance call.

Meshtastic communication would prioritize local hops where they are available and then where there are spans of area without nodes, they could hop across radio broadcasts.

Primary issue would be speed. Next to no bandwidth on a signal like that. Kbps not Mbps. Perhaps an incentive for much better compression as well.

For anyone reading this currently, it appears that regulation bans any form of encryption over HAM radio broadcasts. So I guess that's one reason this won't work.

Sounds like a better idea to implement as a reticulum medium.

So, I setup meshtastic.

Put an antenna on my roof.

Have a decent number of mesh radios. Put one in each car in relay mode.

Setup a locally run LLM and made an interface to it.

Working on setting up a BBS.

I'm in the high density suburbs, I can, when the weather is just right, reach a single node that doesn't seem to be able to reach any other nodes.

If I go on a drive, I can see 5-10 nodes.

Adoption in the mid-Atlantic US is just so damn low, it's not really usable.

We need some antennas up high, but there aren't any reasonable options around me.

The internet will get back up if it goes down. It is very decentralized. Sea cables and DNS is where most of the centralization occurs, and DNS going down is not at all the end of the internet. How man sea cables have to be broken at once for the internet to break, I'm not entirely sure.

Meshtastic is a cool thing and it is very useful, internet up or down.

That won't help for situations where a government shuts down access to the internet.

How resistant would this be to jamming? Iran managed to black out Starlink.

And how trackable is it? Not sure how many people would be prepared to run one of these boxes if the Revolutionary Guard are going to come knocking.

[–] frozenicecube@lemmy.ca 4 points 6 hours ago

It's pretty easy to jam as it's just radio waves. Increase the noise on the channel and the chirps of your msg don't get heard. That said there are some options to vary the channel as a group, and jamming a broad and robust mesh completely vs an area of nodes is a bit harder.

Trackable as in traceable? You mean finding your node location? By default not overly difficult but again, can be set up to make it hard to find you.

Riots fix that, not meshtastic

[–] Olgratin_Magmatoe@slrpnk.net 17 points 10 hours ago (5 children)

Riots are better coordinated when people can communicate wirelessly

A government can shut down a riot of 10,000

It struggles with 10 1,000 person riots.

[–] 7101334@lemmy.world 5 points 9 hours ago

I think at that point it's more of a revolution than a riot, but I agree

No doubt, but meshtastic really is a temporary solution, but a very good solution since it's only necessary for a temporary amount of time. I'm just saying there aren't really many cases outside of a catastrophic mass human extinction event that would disable the internet infrastructure beyond maybe a few years if that. Won't be a library of alexandria moment from a connectivity side, but which servers are still up is the real question

If they shut the Internet and there is a decent meshtastic network they will jam that as well.

This is a non answer. yes, hypothetically they can, but the whole point of finding alternative channels is to make it difficult for them to do so, to the point that they might not even try.

That pessimism of "they can jam it anyways" is like saying do not wear a helmet while riding a bike, if you are meant to die that day, you will die regardless of head protection.

Plus, it will take resources for them to jam things, and the more resources they need to do that shit the faster it will deplete them and the less they can do, it is so obvious I do not know how to write it without sounding demeaning.

Maybe so, but incompetence is persistent within fascist organizations, and it adds an extra problem for them to deal with, which has value for that fact alone.

[–] Allero@lemmy.today 3 points 9 hours ago

There are normally only a few points at which traffic enters the country. Shutting them down will effectively cut you from most of the Internet, and the rest that remains will be fully in the jurisdiction that oppresses you.

Their website is .nl, so it may or may not be Netherlands time, which would be 6PM UTC, I think.

[–] Regrettable_incident@lemmy.world 38 points 13 hours ago (7 children)

So much of our infrastructure uses the internet now that if it goes down I wouldn't be shocked if electric grids, healthcare, shopping, public transport, etc also shit the bed.

I am literally building a network in my town. Love this project, so much fun and useful

[–] foggenbooty@lemmy.world 7 points 10 hours ago

How resilient is something like Meshtastic? My understanding is that anyone can configure their device poorly so that it can become overly chatty, congesting the network. Even in ideal an ideal scenario with properly configured nodes, could this actually survive if it saw more than hobbiest adoption?

I think it's really cool and i like having this idea of a backup communication system, but if has serious range limitations and is likely to be overwhelmed in a no-cell scenario is it even worth it, or is it just fun to play around with?

I've not been recycling my tin cans and I have a whole shitload of string. Happy to share.
