OsmoDevCon 2012 is over...
We just finished the 4th and final day of the OsmoDevCon 2012. It contained four days of in-depth presentations and discussions related to Free Software communications systems, most notably OsmocomBB, OpenBSC, OpenBTS, OsmoNITB, SIMtrace, OsmoGMR, OsmoSDR, rtl-sdr and many more.
I think it was a great chance to make sure the key developers involved with those projects are up-to-date with what everyone else is hacking on. I was especially happy with the presentations of Holger's smalltalk implementation of certain GSM protocols/interfaces, and it seems my small informal Erlang intro has raised some interest.
If anything, the 4-day conference has shown that there is a massive amount of work going on in the various different projects, and that it has clearly grown beyond anything that a single person could still be involved in all the sub-projects.
Personally, I'm happy to see what has grown out of this "we have a BS-11, let's see what we can do with it" that Dieter and I started in 2008. Now we're no longer talking about BTS/A-bis/BSC, but about SS7, MSC, TCAP/MAP, SCCP, HLR, Erlang, smalltalk, DECT, SIM/USIM, COS, SDR, GMR/Thuraya, TETRA and more recently also femtocells as well as NodeBs.
In the spirit of that 2008 presentation Running your own GSM network using the BS-11, Dieter Spaar has now demonstrated his talk on Running your own UMTS network, using NSN or Ericsson NodeBs. I'm really excited to see where that will take us - despite the fact that due to the 5 MHz wide channels, it's pretty close to impossible to get the experimental spectrum licenses that most of us have been able to get in recent years for our work.
As an outlook, over the remaining year 2012, I see progress in the following areas:
- osmo-nitb will get a VLR/HLR split (async database access)
- we will build a stand-alone osmo-msc with A interface
- the signerl TCAP/MAP implementations will be used in production
- OsmoSDR firmware will be completed, the hardware will start shipping
- a new card operating system (OsmoCOS) will emerge
- a UMA gateway will be implemented
- a Free Software GPRS/EDGE PCU and RLC/MAC implementation will appear
- last but not least, sysmoBTS will start commercial shipment really soon now
I'd like to thank our host c-base for having us block their conference room for 4 days, as well as all attendees who have travelled from all parts of Europe, but even the United States and Russia to participate. There definitely will be another OsmoDevCon, though we don't know yet at which point in time.
