This is the announcement for the re-incarnation of our bi-weekly OsmocomMeeting/Berlin meeting.

There is no formal presentation this time, but

  • there will be SIMtrace equipment in case somebody wants to play with it
  • there will be a sysmoBTS with OsmoBTS, OsmoPCU, OsmoNITB, OsmoSGSN and OpenGGSN if somebody wants to play with it
  • The meeting is open to anyone interested in mobile communications. You do not have to be involved with the Osmocom projects in order to attend. Anyone interested in mobile communications protocols is welcome.

If you are interested to show up, feel free to do so. The meeting is "free as in free beer", despite no actual free beer being around ;)

OsmocomGMR: Osmo-GMR now implements voice codec decoder

Added by tnt about 3 years ago

GMR-1 uses an undocumented codec in the AMBE family and as such Osmo-GMR didn't have any implementation of it and converting TCH3 frames to actual audio wasn't possible.

Now, after quite a bit of effort to figure things out, I'm pleased to announce that an open-source decoder is available. It's not perfect and doesn't match the quality of the official decoder but it does produce intelligible voice and will have to do for now.

It's currently available in a separate 'sylvain/codec' branch in the git but should be merged into master soon after a last review of the code.

OpenBSC: osmocom.org server outage

Added by laforge almost 4 years ago

For about one week from March 20, 2013 on most of the osmocom.org severs and services have been offline due to a hardware failure in the physical machine that was hosting all the virtual machines related to the project.

As I was on extensive business related travel, I couldn't go to the data center and take care of fixing the problem myself. So we had the hard disks sent to my home in Berlin, obtain a machine that has the neccessary SCA-80 connector for the old-fashioned enterprise SCSI hard disks and then start recovery by means of an old backup in the data center + rsync'ing the changes via my slow DSL uplink.

The good news is: Everything is up and running again on different hardware, and there is no data loss as the hard disk was fully intact.

In the coming weeks, we will migrate the various virtual machines over to a new (rented) physical machine, sponsored by http://​sysmocom.de/

I'd like to thank

  • zecke for providing emergency recovery for the git server
  • roh for providing an old Sun v20z to mount + read the SCA drives
    ​* http://noris.net/ for mailing the hard disks to Berlin
  • the community for their patience with the slow recovery process

OpenBSC: OsmoDevCon 2013-04-04 till 2013-04-07, Berlin

Added by laforge almost 4 years ago

Dear fellow Osmcoom developers,

it is my pleasure to finally announce the date + venue of OsmoDevCon2013:

  • Date: April 04 through April 07, 2013
  • Place: IN-Berlin, Lehrter Str. 53, Berlin

Like last year, this is an event for developers of the various Osmocom proejects. Reservation and confirmation of reservation is required.

The event is free of charge. The Room is made available by ​IN-Berlin e.V., an Internet related non-profit organization. Lunch catering will be sponsored (so far by sysmocom GmbH, but if any other sponsors come up, we are happy to share the cost).

So all you have to cover is your own travel + accomodation costs, as well as breakfast and dinner. If you are an active developer and cannot afford travel/accomodation, please let me know and I'll see if we can do something about it.

If you would like to attend, please send a message to ​ applying for registration of the event. The registration deadline is March 5, i.e. one week from now.

There is no detailed schedule of talks yet. I will start a separate discussion suggesting / collecting topics in the next couple of days.

More information is (and will be made) available at OsmoDevCon2013

Further discussion regarding the event should be directed at the mailing list, to avoid cross-posting over the various project-specific lists.

Best regards and happy hacking,
Harald

OpenBSC: osmo-pcu (GPRS Packet Control Unit) v0.1 released

Added by laforge almost 4 years ago

After months of work by Ivan Kluchnikov and Andreas Eversberg, the Osmocom GPRS Packet Control Unit (OsmoPCU) has finally reached a point where it makes sense to release a first version: v0.1

There are still a number of limitations and shortcomings, most of which should be indicated in the wiki at osmo-pcu. However, even without hand-over, timing advance loop, power control loop or dynamic link adaption of the coding scheme, it is already a useful implementation for lab-type setups and small, indoor real-world deployments.

osmo-pcu can be used either with OsmoBTS on the sysmocom sysmoBTS hardware, or with Fairwaves' branch of OpenBTS on hardware like the Ettus USRP family or UmTRX.
