Warning: strftime() [function.strftime]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

Improving Free Software based GSM protocol analysis
|Abstract||There is an increasing, but still small number of Free Software projects that directly interact with the GSM mobile network. Examples are gsmdecode, gsm-tvoid and gssm developed as part of the THC GSM project. Other examples are the OpenBTS project aiming at operating your own GSM BTS, as well as the yet-unreleased bs11-abis project, a FOSS project implementing the Abis protocol between BTS and BSC.
The idea of this WorkOut is to look at the current status and define and assign work items to help to improve the quality of current GSM protocol analysis software.
|Pre-requisites||* basic knlowedge about GSM or at least communication protocols * python programming skills (for gnuradio) * C programming skills (for wireshark) * PDF reader (for the ETSI/3GPP GSM specs) * a current version of gnuradio on their laptop NOTE: _no_ actual USRP hardware required, I will provide recordings, all software development can happen basd on the recordings.|
|Speaker Profile||Harald Welte is a freelancer, consultant, enthusiast, freedom fighter and hcaker who is working with Free Software (and particularly the Linux kernel) since 1995. His first major code contribution to the kernel was within the netfilter/iptables packet filter. He has started a number of other Free Software and Free Hardware projects, mainly related to RFID such as librfid, OpenMRTD, OpenBeacon, OpenPCD, OpenPICC. During 2006 and 2007 Harald became the co-founder of OpenMoko, where he served as Lead System Architect for the worlds first 100% Open Free Software based mobile phone. Aside from his technical contributions, Harald has been pioneering the legal enforcement of the GNU GPL license as part of his gpl-violations.org project. More than 150 inappropriate use of GPL licensed code by commercial companiess have been resolved as part of this effort, both in court and out of court. He has received the 2007 "FSF Award for the Advancement of Free Software" and the "2008 Google/O'Reilly Open Source award: Defender of Rights". Harald is currently working as "Open Source Liaison" for the taiwanese CPU, chipset and peripheral design house VIA, helping them to understand how to attain the best possible Free Software support for their components. He continues to operate his consulting business hmw-consulting.|
