LimeSDR support in osmocom:{nightly, latest} package feeds
by Harald Welte 29 Nov '17

29 Nov '17

Dear all, starting from today, we're packaging LimeSuite and (as needed) other dependencies required for using osmo-trx/osmo-bts-trx with LimeSDR in the network:osmocom:nightly and network:osmocom:latest feeds. The package versions are fixed and are not tracking "master" of e.g. limesuite. Only the Osmocom packages are tracking master. Due to the unfortunate fact that the first LimeSuite with osmo-trx support (17.09.0) requiring a cmake later than what Debian 8 ships, LimeSDR support is not working with all of the Distributions/Versions that the rest of the Osmocom stack supports. It appears that LimeSuite also has some build issues on ARM architectures, about which I've submitted an upstream bug report at https://github.com/myriadrf/LimeSuite/issues/151 But at least for x86_64 and i586 architecture, LimeSDR should be supported by the Osmocom package feeds , on Debian 9.0, Ubuntu 16.04, 16.10, 17.04 and 17.10. We will shortly use those packages as part of our osmo-gsm-tester setup at the sysmocom lab, at which point they should receive extensive testing.

Want to do paid work on Osmocom? sysmocom is hiring
by Harald Welte 31 Oct '17

31 Oct '17

Dear Osmocom community, I would like to point out that at sysmocom, we're currently (again) hiring [1]. If you happen to have an interest in open source cellular communications and are fluent in C language development, we would love to hear from you. sysmocom probably doesn't need any introduction here, but just in case: The company was founded by Holger Freyther and Harald Welte, two of the leading OpenBSC and Osmocom developers from the very early days of the project. Today we are responsible for by far the largest number of commits to the Osmocom GSM/3G infrastructure related git repositories. Among our current priorities are automatic testing for the GPRS PCU, generalization of the OsmoMGW media gateway, support for load-based hand-over, inter-BSC hand-over as well as various improvements on the lower layers of the GPRS protocol stack. We're very dedicated to the cause in furthering the capabilities of open source cellular infrastructure from 2G to 4G. We believe in working upstream, no open core or dual licensing. If you have an interest working with an enthusiastic, strong technical and dedicated team of Osmocom hackers, please don't hesitate to let me know, best by e-mail to jobs(a)sysmocom.de Thanks, Harald p.s.: I hope this kind of message is not disturbing to anyone. I think it is important to the Osmocom project to have more paid people working on the stack, so it is justified. The positions we are seeking to fill will work [almost exclusively] on Osmocom, so it's not a random job ad but in the very interest of Osmocom, and hence on-topic for this list.

Video Recordings of OsmoCon 2017
by Harald Welte 25 Apr '17

25 Apr '17

Hi all, the Osmocom Conference 2017 last week was an overwhelming success. We received lots of positive feedback from all sides. Thanks to all the speakers, to the attendees as well as to the anonymous sponsor of the travel grant funds. It is my great pleasure that due to the great support by C3VOC (The CCC Video Operation Center), we have full recordings of all talks given at OsmoCon 2017. You can find the videos on the C3VOC site at https://media.ccc.de/search/?q=osmocon They are also linked individually from the OsmoCon 2017 homepage at https://osmocom.org/projects/osmo-dev-con/wiki/OsmoCon2017 I hope the video recordings will be of help for everyone who could not make it to the event in person. We will also be collecting the slides and put them up on the wiki during the next few days. Please don't hesitate to raise any feedback and/or questions. Technical feedback/questions regarding Osmocom software / projects should be addressed to the appropriate mailing lists, such as openbsc(a)lists.osmocom.org. Feedback to the organizers should be sent to osmocon2017(a)sysmocom.de. Looking forward to the next OsmoCon, which we'll expect to be spanning ore than just a single day.

Updates on Osmocom Conference 2017
by Harald Welte 27 Mar '17

27 Mar '17

OsmoCon 2017 updates There are some updates related to OsmoCon2017, the first Osmocom Conference, held on April 21st, 2017 in Berlin, Germany. See http://osmocom.org/news/68 for the web version of this announcement. == Summary == Summary (for those too busy to read the full post): * Schedule of talks has been released http://osmocom.org/projects/osmo-dev-con/wiki/OsmoCon2017#Schedule * Travel Grants available for participants who are otherwise unable to travel to Berlin: http://osmocom.org/projects/osmo-dev-con/wiki/OsmoCon2017_TravelGrants * Social Event details available, including menu: http://osmocom.org/projects/osmo-dev-con/wiki/OsmoCon2017_SocialEvent * April 21st is approaching fast, make sure you get your Ticket in time. Limited number of seats available http://shop.sysmocom.de/products/ticket-for-osmocon-2017 == Details == === Schedule has been released === The list of talks with their abstracts has been on the website for quite some time, but now we actually have put together a schedule based on those talks. Please see http://osmocom.org/projects/osmo-dev-con/wiki/OsmoCon2017#Schedule for the schedule. As you can see, the day is fully packed with talks about Osmocom cellular infrastructure projects. We had to cut some talk slots short (30min instead of 45min), but I'm confident that it is good to cover a wider range of topics, while at the same time avoiding fragmenting the audience with multiple tracks. === Travel Grants === We are happy to announce that we have received donations to permit for providing travel grants! This means that any attendee who is otherwise not able to cover their travel to OsmoCon 2017 (e.g. because their interest in Osmocom is not related to their work, or because their employer doesn't pay the travel expenses) can now apply for such a travel grant. For more details see http://osmocom.org/projects/osmo-dev-con/wiki/OsmoCon2017_TravelGrants and/or constact osmocon2017(a)sysmocom.de. === Social Event === Tech Talks are nice and fine, but what many people enjoy even more at conferences is the informal networking combined with good food. For this, we have the social event at night, which is open to all attendees. See more details about it at http://osmocom.org/projects/osmo-dev-con/wiki/OsmoCon2017_SocialEvent -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Contribute to Osmocom and receive a free 3.5G femtocell
by Harald Welte 09 Jan '17

09 Jan '17

Dear all, not everyone might have seen the news item that was posted in late December on our website at http://osmocom.org/news/62 I'm looking forward to receiving your proposal on how you would contribute to the Osmocom project if you were to receive one of those free 3.5G femtocells. Quote of the news item below: ------ So please excuse me to cross-post this over several Osmocom project mailing lists. I know that a number of people have either hacked on femtocells in the past, or at least expressed interest in doing so... Osmocom's support for 2G/GSM is mature and widespread. Since 2016, we're taking on the next level: 3G/3.5G. The key to running your own 3G network is to obtain actual 3G cell hardware -- here is an exciting opportunity to get started: No less than 50 femtocells will be given away for free by sysmocom, one of the main drivers of the Osmocom project. To receive a free 3G femtocell, tell us how you will help the Osmocom project drive 3.5G forward if you had one, before the end of January 2017. This marks the launch of the 3.5G Acceleration Project, backed by the Osmocom community. Join us! Find further details on the 3.5G Acceleration Project and receiving your own 3G femtocell for free at https://sysmocom.de/downloads/accelerate_3g5_cfp.pdf. ------ Best regards and happy hacking, Harald Welte -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
