For those interested to read more on AWDL I've listed some interesting articles that I came across during lit review a while back

A research lab from TUD worked on a project investigating Apple's wireless ecosystem Link: https://owlink.org/publications/

Also something interesting that I remembered reading closely linked to AWDL?

Correct me if I'm wrong but from what I understand you were able synchronize multiple SDR systems without dedicated hardware. That's tots awesome! though I did not get how you did..

Its been a while and I don't remember all details but I was trying to synchronize two B210s running on different systems as NR BS and UE.. GPSDOs were too costly and I did not have external PPS. Regardless of what I did, after initial sync the two sdrs would drift by significant amount within couple seconds. I just gave up on solving the problem on hardware and adjusted for timing and freq offset every SSB, and assuming everything is synchronized for two frame duration (2x1024us). I moved out of that project and I still don't know if there's a better way or how mobile phones actually implement RX..
