without having to go through the real layer1 or at least without having<br>
to go through the air.<br>
<br>
But without a clear path to later porting this on a real physical<br>
layer1, there would be little motivation of doing all that work.<br></block=3D

I think what makes OsmocomBB special is the very fact that we do not<br>
have to rely on simulation, but can do the &quot;real thing&quot;.<br>
<br>
Nonetheleess, if somebody was interested in implementing what I&#39;ve<br>
described, I&#39;d be more than happy to help any such project and<br>
include the neccessary support in OpenBSC and/or OsmocomBB.<br>
