Spicy take but I think this whole Lora thing is a dead end bad technology not worth our time.
Wifi HaLow 802.11ah is finally out & available, sometimes at ok prices. We don't really have ad-hoc communication pioneered for wifi, but it's doable and we ought lean into it, rather than using some totally different stack, especially one that is under strict control of a single company.
What we learn doing wifi halow can directly port and improve the rest of ways we connect. That would be grand.
The 802.11ah offerings right now are a mess though. Mostly proprietary and just generally very buggy. I don't know of a single chip that can actually be used with up-to-date Linux. Do you? Be it Morse Micro, Newracom, Taixin or any other, they all suck in some aspect.
Hostapd people also do not seem interested in bringing in any 802.11ah support. So it's crap in that aspect as well. Drivers all fake 802.11n or the chipset offers some garbage AT-command interface and does all of the networking.
On the other hand MeshCore and Meshtastic have similarly terrible codebases as far as I've seen. At least they're somewhat usable though.
Honestly no clue why these software stacks are all this dangerously written, unstable and haven't improved in years.
Mesh networking is still mostly a playground for hobbyists and hacky, built-on-the-knee implementations. People love shipping a cool PoC, but as soon as the boring stuff starts - stabilization, drivers, edge cases - everyone bails to chase the next hype protocol. We’re left with mountains of half-baked C++ legacy that nobody dares to refactor because the whole house of cards would collapse iirc
LoRA is extensively used in Ukraine right now as a UAV control rf link to bridge serial uart from ground control system to uav. In its most narrow channel configurations at lower bps and using things like 1.2GHz tuned yage antennas it can have some very robust jamming resistance.
Eh, I've played with 802.11ah and it's very long range for the power, but way too stateful for the use case that these mesh protocols serve. If you go out of range it's several seconds to re-establish a connection. I've worked with proper mesh radios (Silvus, etc) and they work very differently.
