Well, indeed the idea is indeed to get more actual real-world data.
Knowing what is happening in the air is interesting by itself, IMO. The first step is to know what is going on, the next step could be to do something about it. This is something that we can do/know right now, I think that step 2 should depend on step 1, not the other way around.
I found this post very enlightning for example:
I’m not sure what you mean with other TTN deployments. Sure there are other LoRaWAN networks they will cause some interference, and you can’t do much about that. I think it’s good to know the extent of interference from other networks too.
Right now, any discussion about the FUP/FAP is purely based on assumptions only.
