alt Hacker NewsSo you have the mesh and then what?
Do people communicate to distribute prohibited anti-government propaganda or is it a network of people who otherwise be too shy to talk to each other by other means?
What is the use case?

If you see this technology and think "wow! that solves [problem I already have]" - then it's great.
Otherwise, you buy a couple, set them up, spend a week or two sending very slow and unreliably forwarded messages that mostly amount to "hi! i have an ACME 32ABC radio! What do you have?", and then put it in a drawer or sell it on.
Just like ham radio, really.
It runs independently of internet and power. One use case is a group of people in a remote area (hikers, hunters) carrying their own node and being able to communicate via text over several kilometres.
There is no real use case, IMO. I setup a few nodes a couple of months ago. It's mostly no activity, punctuated by some random "can you read me" type messages, and for some unknown reason people who think there is something impressive about them having a node on a commercial flight.
The entire thing would fall over in any kind of scenario where you needed to rely on this janky mesh network as a primary means of communications.
It can be fun/useful for very out of the way things where you have a handful of people out camping, or other off-grid situations. But frankly even in those cases there are far better/established ways to keep in sync if you need to (eg: FRS).
This stuff is mostly a solution looking for a problem.
Its one of the few places you can be fairly sure you're chatting to people, not bots, who have no agenda to sell you anything.
Of course if it ever becomes popular, that will quickly change. But for now it is like early IRC.
It's not all people trying to skirt the law. It's kind of like HAM radio as a hobby. It's fun technology that lets people do cool automation projects and sure with a mesh connect to other people. Imagine you have a few acres of land and want to turn on sprinklers or something.
A lot of people use it just to chat with friends and family in a fun way.
Of course the preppers and privacy evangelists see it as a means to get ready for living in a hostile environment. Being fair to them, things don't look awesome in the US.
I bet a few criminals use it, but it's still very niche.
Just like ham radio, it's a an interesting technical hobby for those that may get excited when their little 0.25W radio hits a repeater 80km away.
More practically, I'm going to try it out while camping this summer. In areas with low or no cell coverage, my phone is useless or dies quickly. Throw a repeater in a tree, and hand your friends nodes.
The use case is off grid communications for whatever you might need.
95% of it is people just doing ping? Pong! In chat.
The cheapest devices are like $10. Order one and have a go.
Digital Radio Hobbying, think HAM radio but with a microcontroller and apps.
Being nerdy.
But also you don’t build these things when you need them (it will be too late), you need to build them before you need them.
I built one and found absolutely no use for it. No one ever, and I mean ever, answers you. It's sort of like ham radio, where you get your technician license and get on a net and discover people are just talking about their antennas. Except it's worse, because all the antenna discussions are happening on Reddit and Discord and not on the network itself.
People are very enamored with what you could theoretically do with it, but they never actually do any of it. It's a hardware fetish, it's all about building boxes with solar panels and seeing how many nodes you can light up on the map. Reminds me of another ham radio thing I never got into, "contesting".
> What is the use case?
It's primarily just an experimental system. Demonstrating that fixed infrastructure isn't actually necessary to communicate.
Beyond that, it's a mixture of HAM radio for communicating with people outside of your immediate circle, and disaster prep.
The best realistic scenario I can see for using it is after a sever weather event like hurricane, tornado, tsunami, etc. that takes out significant comms equipment. Having an ad-hoc network pop up using battery powered nodes able to setup a secure comms channel to organise aid deliveries would be a powerful tool. But existing infrastructure is resilient enough that it's not actually necessary in modern times.
Beyond that, it's probably more of an IoT type thing. Setup a bunch of nodes across a significant area of land, run machinery, sensors, etc. remotely via a self-healing mesh network.
