Thanks to threads like How can I see if ADR (Adaptive Data Rate) is working with my end device (MultiTech's mDot module)? and ADR - not what I expected I have a good understanding of how ADR is supposed to work in practi… --- ## [What does spreading factor mean?](https://www.thethingsnetwork.org/forum/t/what-does-spreading-factor-mean/14886)

Hey guys, I already checked the forum and the Internet for an explaination of the Spreading Factor (SF). I found out that LoRa automatically choses a factor between 7 and 12.

Hi! From what I can see on my gateway data, some devices uses much more than the DC they should respect.
