Location and Seats

We like to be located close to the PoC, in order to simplify communication with the PoC and to manage GSM helpdesk togeter. Further, we will bring many classic analogue mobile phones (small ones and really big ones), as well as radio equipment.

At 31c3..33c3 we had a perfect location. As always, it was organized to our full satisfaction.

Special things this year


Osmocom-Analog, a project that documents the functionality and knowledge of former analogue mobile networks. The included software allows the emulation of these mobile networks to communicate with Historical mobile phones again. This software is available at Osmocom-Analog website.

This year we will have 7 classic analogue mobile networks with variations for different countries. Yes, base stations! The emulation software was developed in 2016/2017 and is used to connect classic mobile phones to the phone network of the congress. This time we use SDR for better reliability and more channels. If you have one of these phones, bring it:

   A-Netz (first German mobile network)
   B-Netz (second German mobile network)
   C-Netz (thrird German mobile network, cellular)
   NMT (Scandinavian/Benelux/Austrian/Eastern Europe... cellular mobile network)
   AMPS (American cell phone network)
   TACS (British/Italian cell phone network)
   Radiocom 2000 (French cell phone network)


Software defined radio is our friend!

Virtual Reality

How to record VR video and how to playback.

Teletypewriter Osmocom-BB (BTS)

We will set up a teletypewriter again to send and received SMS.

We use a special interface to connect a teletypewriter to a PC via USB. The SMS is transfered via open source software OsmocomBB, an open source baseband GSM stack.
