It will be there to talk about GSM in general and in particular OpenBTS - Harald Welte (project leader OpenBSC ) promises to run for the congress local GSM network , for fans of GSM will be allocated a special place for dialogue, experimentation and collaboration, and the list of lectures is such lectures:

1. Playing with the GSM RF Interface
2. Using OpenBSC for fuzzing of GSM handsets
3. GSM: SRSLY?

I have also come out there with a Lightning Talk and introduce our timebase before the public.

Everyone who stays at home at this time we can safely envy. ;)

PS However, all performances will be available in the online video of the Congress, and a couple of months - in a good quality are available for download on the site.

Published in the network video performance by Steve Song (Steve Song) on TEDx, in which he tells about the Village Telco and Mesh Potato , innovation in the modern world, telecommunication operators and why it is now possible to radically change the situation with a link on the African continent. His analysis of modern trends in the development of communications, he brings to four phrases:

1) Tinkering is the new Inventing
2) Emergence is the new Order
3) Quantity is the new Quality
4) Atoms are the new Bits

About the Village Telco

Village Telco - a non-profit open source project, funded by the Shuttleworth Foundation , and aimed at radically reducing the cost of communication for the inhabitants of the African continent. Here it competes with OpenBTS, puts the same purpose, but in my view, these projects rather complementary. And this is confirmed by the warm relations between the representatives of both projects.

This is not exactly news, but let it be. :)

With the gracious permission of the author (Joshua Lackey), I reliznul kal-0.2 . Kalibrator, popularly known as 'kal', - a utility to check the accuracy and stability of the reference generator of your USRP. As a reference frequency used by the next sync with your base station. But the frequency of the base station you have to pick your own. ;) You can use any phone with the included NetMonitor, or the USRP in spectrum analyzer mode (usrp_fft.py).

The difference between the kal-0.2 of the kal-0.1 in the possibility to choose a side USRP (A or B) and antenna (RX / TX and RX2).

New release OpenBTS 2.5.1. Archives of the source is traditionally available on the SourceForge download page . Release 2.5 contains several bugs and was almost immediately replaced by 2.5.1, so do not be surprised. :)

In addition to correcting many problems in this release, there OpenBTS SMS-server smqueue, written by John Gilmore (John Gilmore) , co-founder of EFF. The server implements the RFC3428 store-and-forward SIP-server.

Note that when upgrading from 2.4 you must update the registration data Asterisk. Now SIP-names which registered mobile phones, starting with letters «IMSI». Ie phone IMSI 310410186585295 would be recorded under the SIP-name «IMSI310410186585295».

The release includes a transceiver to work with standard USRP with 64MGts reference clock, and to work with the reference clock 52MGts. All are encouraged to use it 52MGts reference clock, as the transceiver for 64MGts develop further and will not be filed just to make easier for people to start experimenting.
