I'm interested in building a network that is based on the LoRaWAN networking protocols. I've seen multiple references to LoRaWAN supporting a mesh configuration (instead of the standard star network topology), where there might be multiple hops between various nodes for a packet to reach a gateway.

Are these protocols (particularly the mesh aspect of it) published anywhere? I can't seem to find them.

For this particular project, I'd like to use these same protcols, but with custom radio hardware (on a different frequency band from LoRa).

Many mesh implementations are based on Thread, which is one of the components of Matter, and is based on 6LoWPAN, which itself uses 802.15.4 wireless communications.

I believe Pycom’s mesh on LoRa used Thread as well, but I don’t think it’s open source. Not sure what other LoRa-based mesh implementations exist.

If you are interested solely in the repeating aspect, IIRC the LoRaWAN spec has a few details about that, but it’s mostly just a few fields in headers and the like.

There is a free, open source implementation of Thread, namely OpenThread, by Google. No idea if it’s usable over other technologies than 802.15.4.

Note that mesh is not magic: nodes acting as routers/repeaters will usually need external power sources (they can’t run on batteries, since they need to be listening all/most of the time). A few (non free) technologies say they can use battery-powered repeating nodes, but they’re the exception (and I don’t know how true this is in practice).

What kind of underlying protocol do you want to use, and what are your requirements/needs?

  • Thanks for the info. All nodes actually have their own external power sources, and I'm actually using HF radio at a much lower frequency than LoRa. I was mostly interested in the routing algorithm that is used.

  • Some sources say LoRaWAN mesh is based on RPL, though I don’t think it’s an official thing. But a “LoRaWAN RPL” search on Google yields a large number of results which seem interesting.
