An Introduction to Meshtastic

Definitely interesting for special use cases. But I don't think the wireless carriers have anything to worry about here.

I took a plunge into learning about mesh networks, specifically because I love the idea of p2p/decentralized systems of communication. To be honest, I was surprised to find that my expectations for “where we are at” with this type of technology was pretty off-base. For some reason I thought by now it would be straightforward to do a little more than text messaging over a truly public and decentralized off-internet mesh. Maybe I’ve missed some things in my search (still learning!) and someone can correct my understanding.

The Reticulum Network Stack is a more generic lora capable protocol. It is intended to run over almost any two way link so it's less bandwidth efficient per packet than Meshtastic but in return it gives you packet routing rather than flooding. It can be run over TCP, LoRa, WiFi, etc.

https://reticulum.network/start.html has an overview and how to connect.

There is a manual with a lot more information on how it works and the ideas behind it at https://reticulum.network/manual/ however it's quite large and not really a user friendly guide

If you just want to play with it https://reticulum.network/manual/software.html has a list of clients and software using it.

I had never heard of this before, then last week I watched a video about it and was hooked. Now I'm seeing it everywhere!

Meshtastic and Meshcore are both cool LoRa-based mesh text messaging that operate in an no-license-required band. While this limits your transmit power, it doesn't prohibit encryption - the inverse of most ham radio rules!

Some cities have thriving communities of Meshtastic and/or Meshcore. You can look at maps of coverage to get a very general idea - in my experience, most Meshtastic nodes are NOT listed, while a good number of Meshcore nodes are.

Meshtastic treats the mesh as dynamic - clients are assumed to always be moving, so transmissions flood between different nodes that are in eachother's reach.

Meshcore has a static layer - repeaters that are assumed to be in fixed positions - and a dynamic layer - companions that move. With fixed and hopefully reliable connections between repeaters, routing paths between two users can be 'cached', which avoid the bandwidth overhead of flood routing.

You can get started with a low cost ($30) transceiver board and an SMA antenna ($10) for the ISM band of your region. Stick it in a box an mount it somewhere high up, and see if you can pick up any other nodes!

That article seems to be about how Meshcore split into two, with one contributor forking the code and taking the previously official website with him.

There's no mention of Meshtastic.
