From 25C3 Public Wiki
 Description of the Project
There are a number of GSM hackers at the 25C3 this year, working on projects like
- OpenBTS (http://openbts.sourceforge.net or http://gnuradio.org/trac/wiki/OpenBTS)
- BS11-Abis (Implementing GSM BSC, MSC and HLR on top of mISDN)
- The THC GSM project (http://wiki.thc.org/gsm/)
- The new GSM project page (https://svn.berlin.ccc.de/projects/airprobe/)
We're planning to set ourselves up at the Hackcenter, and will bring quite a bit of equipment for hacking, including
- USRP with RFX900 and RFX1800 frontend
- another USRP with BasicRX and RFX1800 frontend
- Siemens BS-11 microBTS base station
- Some Willtek 4100 Mobile Fault Finders and matching test SIM's
- Some TSM30 mobile phones
 What we plan to do at the 25C3
- Work on improving the bs11-abis code (related to http://events.ccc.de/congress/2008/Fahrplan/events/3007.en.html)
- Test and improve the passive GSM scanner projects gsm-tvoid, gsmsp, and gssm
- Improve the wireshark protocol analyzer for GSM Um and GSM Abis protocol
- Test OpenBTS call control with a wide variety of handset models.
- Get some opinions on core network integration strategies for OpenBTS.
 Our requirements
The amount of space is actually a bit more important than the amount of seating (chairs), since we'll bring quite a bit of hardware with us.
Something like six chairs plus some extra table space should do.
Can someone bring along a spectrum analyser and any other RF hardware related testing tools?
