sylvains talk from 29c3

[Vic Delorge]

Speaker: Sylvain Munaut
or how to turn a phone into a BTS


The calypso baseband and its companion chips are used on the Motorola C123
among other and are now well known for being supported by the Osmocom-BB
open source GSM baseband implementation. A couple years ago, it was hacked
a little further by using it as a raw bits capture device allowing the
interception of GSM traffic very cheaply.

This talk will present some further work on that platform, showing that
just because a device wasn't design for a given task doesn't mean it can't
do it. More specifically how you can hack this phone to act as a GSM
basestation and broadcast your own network.
