OK, so it should be announced more as an field test to help us getting in touch with problematic handsets and other issues. Fine with me.

Hmm, ok. Do you remember the tent we had at the last CCC camp? I may be able to get that one again. Also some tables and banks. That should give us enough place for the GOC equipment and space to hack. Will call soem people over the next days and see if I can get it again. What worries me a bit is the transportation. We brought the same set even to WTH four years ago, but we had two fully packed cars. Well, we will figure something out.

I was thinking along the loines to hand out the SIMs for free. Was just an idea to offload some of the registration work from the actual event. I think we can strike that idea. Giving the information that we don't what do cover all people and announce it as a field test in combination with maybe implemented SMS token register it does not make much sense anymore. :) > > > * making sure the network runs and OpenBSC / hfcmulti gets restarted in case > > > something hangs. > > > > Should be the job for the same people running the GOC (GSM Operating Center) ;) > > heh. well, we can have a simple script that respawns the two (in the right > order) if bsc_hack dies.

He will bring his BS-11. And another big item to transport on the list. ;) regards Stefan Schmidt
