LoRa Common Settings

[mikehill-notabot]

Has there been any discussion on having a common listing of LoRa settings for RNode?

For example in ANZ :
Freq 919.875 Mhz
Bandwidth 250 kHz
Spread 9
Code 5

If 2 people (who didn't know each other in advance) had the same settings, ended up in the same general area and both had RNodes they would at least one pre-determined common interface for LoRa

Thoughts?

There's been some discussion and these are the points as I remember them.

• Legalities vary from region to region
• Terrain varies from region to region
• Congestion varies from region to region
• This is a network-centric decision, especially with fixed infrastructure

Basically, my takeaway is this is best served by local users forming groups and setting standards for their local nets. This allows for better optimization for local conditions and keeps the decisions where they should be: in the hands of the end-users.

There is some value in regional standards, but again, this is best served by the local users, not the network stack itself.

I highly encourage local groups to set and publish local standards, then post about them here or in another central repository.

Another major advantage is network congestion. If Chicago has a high speed LoRa system called ChiNet, just to not waste a good name on a meta-variable, and a much slower, more compact SleepyNet, then users passing small bits of telemetry can avoid the congestion of the main talk-group.

So, because I ramble and I'm not actually awake yet, I'll sum up:

• This would be helpful
• Local groups (even of just one person) should define and run local nets
• Linking these to larger nets is optional
• These should all be published to assist newcomers and prevent duplication of effort.

You shouldn't afraid to ramble when not actually awake, because that was great :)

For a newcomer like myself, who want to create a local Reticulum network with mainly LoRa nodes, it would be helpful to have guidelines or maybe a tutorial on picking the right LoRa settings. Are there specific considerations for a Reticulum network, or is it enough to follow generic LoRa advice?

Should I be able to figure it myself or is it best to recruit an experienced amateur radio operator?

Edit: To answer my own question, this LoRa Bitrate & Sensitivity Calculator was a very useful tool! I have a feeling I'll end up as a radio amateur myself.
