[ANNOUNCE] First OsmocomGMR code release
by Harald Welte 16 Oct '11

16 Oct '11

First Osmocom GMR code release As some of the readers may already know, a couple of Osmocom developers have been working on a new sub-project: OsmocomGMR. The primary goal of this project is to provide a reusable and clean implementation of the various layers of GMR-1. What is GMR-1 ? Well, it stands for "GEO Mobile Radio" and it's a set of specifications describing a satellite based mobile phone network heavily inspired from GSM. One of the major commercial operators of GMR-1 technology is "Thuraya", providing coverage over Europe/Africa/Asia/Australia. So far the implementation focused on the lowest layers: * Physical layer with FCCH sync and demodulation support for * pi4-CBPSK and pi4-CQPSK bursts. * Channel coding layer (scrambling/puncturing/convolutional coding/crc/interleaving/...) And some ancillary tools to exploit those: * A good capture tool to listen to particular ARFCN(s) and channelize them properly * Wireshark support (BCCH only so far) The first 'demo application' using all of the above provides functionalities similar to what airprobe is for GSM: An air interface protocol analyzer that goes all the way from capturing data off-the-air to sending packets to wireshark for analysis. Limited to BCCH only currently but this will evolve with time. Development was mainly done by Sylvain Munaut, with help from Dimitri Stolnikov (early signal captures and his great capture tool), Harald Welte (initiating the project) and Steve Margraf (testing different setup and antenna ideas). If you'd like to know more, you are encourated to read the wiki (http://gmr.osmocom.org/) and join the mailing list (http://lists.osmocom.org/mailman/listinfo/gmr) -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

In case anyone else is looking for a copy of that code and all known mirrors have been pulled: I have a copy in my possession, and I've been meaning to put it up on my FTP server, i.e., a new public mirror that would be completely shutdown-proof. (I don't use clouds, I run everything on my own physical HW in my own physical control, housed in my own personal datacenter on my own soil which I have declared to be my own nation with my own laws, so no one in the world can make me take anything down.) However, I am very very technologically-backwards, and my current server HW/OS platform is too ancient to host a 500 MiB blob. (The booty is in the form of an ISO image and appears to contain a huge Windows-based development environment in addition to the actual source.) For ages I've been meaning to set up an additional FTP server on newer HW that can host such big stuff, but that progress is very very slow-going for a bunch of personal reasons. Because I consider it to be my fault that I still haven't followed through with my ages-old promise of setting up that new FTP server, I hereby attempt to make up for it somewhat by making the following offer: if anyone would like a copy of that TSM30 source code, is not able to find it anywhere else, and is not willing to wait however many more months for me to set up that darned server, you can give me your snail mail address and I'll send you a CD-R recorded from that 500 MiB ISO image. With the above out of the way, I happen to have some unanswered questions about the TSM30 phone itself which I wonder if perhaps someone in this community might have some answers to, so I've decided to use this thread (started by someone else to whom I have no relation) to try asking them. :-) (And yes, I've already tried Googling quite extensively.) OK, here we go: 1. Would anyone happen to know the basic specs for the TSM30 phone from an ordinary user's perspective? Which GSM bands does it support? What kind of features does it offer? Judging from a cursory bird's-eye-level look at the source code, it seems to be a few notches above a basic primitive phone like Mot C123, but not quite a smartphone either. I realize that one can probably extract all the answers from the source if one were to study it for months on end (I had no idea it would be this huge!), but I was wondering if anyone already happened to know the answer. Basically I'm trying to decide if it would be worth my while to try to acquire an actual TSM30 hardware unit - which in itself seems to be very non-trivial. 2. Has anyone been able to find a service manual and/or schematics for this phone? 3. Does anyone know the hardware in the TSM30 compares against other Calypso-based phones, such as Mot C123, Openmoko GTA02 or the Leonardo reference design? What are the similarities and differences? TIA a lot for any clues, MS

Ciphermode
by Ronny Moser 02 Oct '11

02 Oct '11

Hi guys.. I have a question about cipher mode. I saw, that currently a5/1 and a5/2 is implemented. Now, I want to force the phone to use no encryption (A5/0). Is it enough to disable both of these algos? Because when I tried that, I was not longer able to sign in.. Are there any patches that are necessary, or may it be, that the network is not willing to provide a non-encrypted connection? Usually, the phone is using A5/1 and with that algo, everything is working fine.. Thanks for your help. Ronny
