Recently, I attended the OpenBTS workshop organized by David Burgess. The 4-day workshop was hosted by Dieter Spaar in his lovely Bavarian farm. Beside the many participants from across the globe with a variety of backgrounds, Harald Welte and Karsten Nohl were also in attendance. I won't get into much detail about the covered material since I'm sure they will be properly summarized in the OpenBTS Blog soon. Instead, I will just share some snapshots.

David Burgess did a superb job at covering a large set of topics.

Dieter Spaar had a neat UNIX-based spectrum analyzer box running.

Harald Welte gave demonstrations of OpenBSC and OsmocomBB.
