People are talking about USRP for a long time already. USRP is a standard hardware for GnuRadio works nowdays. > I downloaded > the EDA source files from gnuradio SVN repo, had a glance on its BOM, > though I didn’t calculate price from digi-key, neither asked how much > the PCB and assembly would cost, I don’t think a make a USRP clone > would cost more than $300, PCB and assembly cost will strike you for quantities you may be able to produce for such a task. > However, I read that the clock and ISM band filter need to be > mortified before you can use an USRP to run openBTS successfully.

Actually there already several projects aimed at creating hardware for GSM related tasks. Close-Haul (US-based startup) announced their GAPFiller recently: https://sourceforge.net/mailarchive/forum.php?thread_name=b761e2df0912101235x48169208p12d81a359cf21...@mail.gmail.com&forum_name=openbts-discuss It is specifically crafted for GSM and is promised to be available in the first half of 2010. We're also working on hardware for OpenBTS, i.e. it's also GSM tailored. Our version will be available by the end of 2010. I know there are more projects aiming at the same target, so I think it's worth just waiting a little bit. Most problem here is that projects such GAPFiller and our one develop hardware for GSM transceiver, not for interception so you may not be able to capture both uplink and downlink. Yet, we personally will try to make this possible. I can't promise this until I see decent interest in such devices, but we'll try to make this real. If you have an interest - please contact me (off the list). -- Regards, Alexander Chemeris. _______________________________________________ A51 mailing list [email protected] http://lists.lists.reflextor.com/cgi-bin/mailman/listinfo/a51
