Hi all,

after some days digging into the various tools around the GSM opensource
playground arena i started understanding better the various piece of

It seems to me that there's a net separation between the GSM
implementation stack of OpenBTS and Osmocom, also because the projects
are born with different goals.

With the current bb implementation of Osmocom inside Calypso based
baseband processor of motorola, all the DSP logic is done directly by
the mobile phones chip, right?

Which with OpenBTS, it's OpenBTS itself that does the
modulation/demodulation along with the USRP.

Is there some project and or ideas to bring together the DSP codebase of
OpenBTS, together with OsmocomBB to make a MS terminal based on USRP1
device with RFX900 boards?
