This is the announcement for the latest incarnation of our bi-weekly Osmocom Berlin meeting.

November 07, 8pm @ CCC Berlin, Marienstr. 11, 10113 Berlin

There is no formal presentation scheduled for this meeting. Holger might present about (regression/unit) testing inside the Osmocom project.

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 ;)

Christian has posted a detailed status update to the osmocom-sdr mailing list, describing his progress with enhancing the sample rate from 500 kS/s to 4 MS/s (at 14 bits ADC). Also, some impedance mismatch between tuner and ADC was fixed.

The benefits of this are not only available to the users/customers of the next generation hardware, but there will be a stacking board to upgrade the existing OsmoSDR units.

The full details can be read in his ​mailing list post

At this point there is no ETA yet when the new design will be available,

August 22, 8pm @ CCC Berlin, Marienstr. 11, 10113 Berlin

There is no formal presentation scheduled for this meeting. However, updates will be provided on various current developments, such as

• Progress on the CC32RS512 smart card (osmo-cos)
• Possibly: Status of current attempts to get CSD implemented in OpenBSC

The team of developers of the open source project GNSS-SDR proudly announces that the latest version of our GNSS receiver supports the realtime operation using RTL-SDR compatible dongles.

They achieved GPS position fix with what is probability the cheapest GPS receiver ever made. If you have a RTL2832U based compatible DVB-T receiver you can have also a GPS just adding an active GPS antenna and our free GNSS software.

All the details can be found in this article

I've merged the DECT tree with the Linux 3.5 release. Experimental support for US-DECT for the UPCS band will also be pushed out soon.

This is the announcement for the latest incarnation of our bi-weekly Osmocom Berlin meeting.

August 8, 8pm @ CCC Berlin, Marienstr. 11, 10113 Berlin

The schedule is as follows:

20:00 Contemporary smartphone hardware architecture (Harald)

• Harald will be talking about hardware architecture of modern smartphones.

21:00 Informal discussions

• Demo of OsmoPCU on sysmoBTS
• Status of new SMSC
• Planning phase of custom calypso board

If you are interested to show up, feel free to do so. There is no registration required. If the initial part is not interesting to you, feel free to join us later at 21:00. The meeting is free as in "free beer", despite no actual free beer being around ;)

Osmocom-BB team member Sylvain Munaut gave a talk at PHDays 2012 about abusing the calypso phones.

It mostly focus on the technical details of the DSP hacking that was done previously to use those phones as passive sniffer and demonstrates some more hacking to turn those phones into BTS.

The talk video is available ​here and the slides are available ​here

There are something like 16 units of OsmoSDR that we have produce and which are able to sell to interested developers.

However, as there are only 16 units right now, and as the firmware and host software is in a barely usable but incomplete state, we would like to make sure that those 16 units get sold to people who actually have an interest (and expect to have at least some time time!) to fix and improve the current shortcomings.

So if you want to be among the first 16, I suggest you contact me at Harald Welte <laforge@…> and include a short description of who you are (if you are not a Osmocom regular) as well as some incidcation that you are actually going to work on improving the code. If you already know an area that you'd like to work on, please state that, too.

The price will be 180 EUR incl. VAT (that's 151.26 EUR without), i.e. the same price as for the units that will later be sold openly.

I have put together a wiki page with the current status at Status to make you aware where we are and what is missing.

Thanks in advance for your willingness to be early users and help us to improve the codebase.
