Hi all,
How to implement this relay feature?
Wait three to five years, it should be ready for mainstream use by then.
Or be the first!

Have TTI given any indication that they are planning to introduce the relay feature ?

i think …, not introduce yet. that feature is great for Lorawan.
Also see https://www.dryad.net/ , they have implemented something like that.
If I read what Dryad is doing, looks like they are using it already.

Great ?
Not so sure myself.
Whilst a permanently listening LoRa device acting a relay can in effect double range, the relay feature described uses CAD to detect on air activity and when I tested this there was a drop off in effective sensitivity, i.e CAD did not detect the weakest signals that could have been received.
And if you need to put in a lot of these ‘relays’ to reach distant nodes, then maybe a better placed Gateway is what is needed.
Time will tell.

Yes, they are reporting using a (patent pending) mesh setup, although there are public domain mesh setups already.
But forest fire detection, does not in the vast majority of circumstances, generate much traffic at all. Maybe a once a day I am alive message …
A mesh setup in a typical TTN scenario could generate huge amounts of traffic, so could well struggle to stay legal. Perhaps this is why the direct relay approach is being suggested, rather than a mesh solution.
