27C3, CCC Camp 2011, and 28C3 all had their own GSM networks as well. http://events.ccc.de/congress/2011/wiki/GSM#GSM_Network_at_2... It was really interesting talking to the crew running it and discovering how GSM works. Hopefully they'll be back this year at 29C3

Wow, I saw 27C3's little experiment but I didn't realize 28C3 had a network connected to the public phone infrastructure.

Yep. For those like myself who didn't have a german SIM for the week it was very useful.

Also HAR and I believe Burning Man had GSM networks too.

Burning Man's GSM network used the GNU Radio project:

The Suggested Reading section gives a really good starting point to DSP, electronics (including Radio and RF design), and Programming (C++ and Python). It's been a great help to hobbyists like me.
