That stuff is good for drone warfare, mesh networks already been used in Ukraine E.g. drones geographically organize themselves into a chain with each of them serving as a mesh-network node, then each of them, including the tip of a chain, can be controlled by operators, and the whole setup is a closed network which works without requiring Internet access

It sucks how everything feels like a toy. I think meshtastic is the closest thing to a “product”. They made a bunch of bad architectural decisions that are haunting them now like how nodes broadcast its info.
It doesn't surprise me. This is a deep networking problem and very few CS people know anything about networking or how to design clean, fast, low-overhead network protocols and systems. If IP were designed today the packets would have 500+ bytes of plain text JSON as headers and the spec would support hundreds of extensions.

yes, considering the options.
What are the options?
Correct me if I am wrong but I thought the primary appeal of LoRa was range? Also isn't the primary factor in making long range radio go through things is the frequency? So 2.4ghz is the same frequency as consumer wifi right and thus would propagate about the same right? It doesn't seem like this would be that useful except that the protocol is LoRa so you can have higher bandwidth between two devices if they happen…
"Going through things" isn't always necessary / is avoidable in some deployments. And 2.4GHz signals can propagate an okay distance between nodes if there aren't things to go through. (Globalstar's emergency SOS satellite constellation uses the n53 band, which is right above the 2.4GHz "wi-fi" band, and it propagates between handsets and LEO through 1400km of air just fine.) So you could probably pull off a 2.4GHz me…

TBH Meshtastic's code isn't great either. It's neat to play with but not robust.

Mesh radio is a fun way to chat with radio nerds in your area. Not a serious infrastructure.

Is there a better designed mesh project like those two getting built that you know of? Reticulum?
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…

Because they are toys. For real work it makes so much more sense to use the internet. With the new satellite tech you can reach the internet everywhere. Mesh radio is a fun way to chat with radio nerds in your area. Not a serious infrastructure.
