In the LoRA/radio device sense, Meshtastic[1] is probably the easiest to get started with. It's the biggest player in the space, has devices that come pre-installed and configured, the most likely chance of making contact with someone else, etc. MeshCore[2] is the other major player. It's newer and tends to have been adopted by communities that have run into issues with large Meshtastic networks.

If you meant PC-based mesh networking, I'll leave someone more knowledgeable to speak about that :).

I've had some experience with both Meshtastic and Reticulum, and Meshtastic software was mostly unusable for me even with 3-node networks. E.g. a node sends a message and gets a successful delivery notification from the receiver but the receiver fails to display the message to the user. Reticulum was mostly working fine. Haven't tried MeshCore yet.

Meshtastic also doesn't really... work. Let me qualify that. You can get a couple of nodes for cheap, and you can (with a bit of work) get messages to go between them. The problem is coordination between nodes is required for the network as a whole to work. Specifically, user adjustable node -local settings can overwhelm the network for everyone else around you. Defcon "solves" this by providing firmware to flash with preconfigured settings tuned for the event. But hopefully this makes the problem obvious - in some other scenario that you might hope to use them - and TBC, my goals for a long range, non-cellular network mesh network are for connectivity during a hurricane/flood/firestorm/earthquake/tornado/etc.

An open implementation is preferred, because it drives down the cost of hardware and lets users purchase the grade of hardware they want. But if it doesn't work, an imperfect proprietary solution(s) available now > hypothetical perfect future solution.

Lora, especially on regulated bands that are the most used ones, is designed for very small, very infrequent messages. It isn't suited for real-time chat (nevermind secure) and so I think you can't really make it work while respecting transmission regulations.

There are lora modules that work on the 2.4GHz ISM band but then you probably need to consider whether Bluetooth is not a simpler choice if range is not the no. 1 concern.

It is encrypted on private channels and direct messages.

I don't know from where your information's are from, but for sure not from reality. Voice encryption/scramble on Amateur-Band's is not allowed, everything else is ok.

It seems like you're saying voice encryption is not permitted, but data encryption is? This is not true in the US. Any encoding used for the purpose of "obscuring meaning" is not permitted on amateur frequencies. Even using code phrases like "the eagle has landed" is arguably not allowed. There are some narrow exceptions for things like satellite control codes, but nothing that applies to hobby mesh nets.

Here is the relevant Part 97 rule: https://www.ecfr.gov/current/title-47/part-97#p-97.113(a)(4)

> No amateur station shall transmit: [...] messages encoded for the purpose of obscuring their meaning, except as otherwise provided herein; obscene or indecent words or language; or false or deceptive messages, signals or identification.

[selimthegrim]

So numbers stations fall under as otherwise provided?

I know what features it claims to have. The question is how well this can work on bands (US915, EU868) that very strictly limit the amount of time a device may transmit. IMHO you can't really have interactive chat on a mesh network over lora in those bands.

[BSDobelix]

>I know what features it claims to have.

Yeah...no i don't think so.

>IMHO you can't really have interactive chat on a mesh network over lora in those bands.

Devices allow 10% Airtime on ISM here (EU) that's about 300 messages (with 255 characters) per hour, and yes interactive chat is possible with around 20 seconds of lag.

EDIT: I stop here, so much half knowledge that sounds educated but is in fact just wrong and TBH not even sure if i talk to a selfhosted AI.

Have a good Day.

My dream would be to have something like Yggdrasil[0] over some kind of mesh-based transport. Yggdrasil already does a good job with routing, it just needs a mesh-based transport IMO.

Big fan of MeshCore; been using it recently and it Just Works. Especially where I am in the USA Pacific Northwest, the mesh is always hopping with conversation. I have run into delivery issues a single digit number of times over hundreds of messages.
