to go through the air.

But without a clear path to later porting this on a real physical
layer1, there would be little motivation of doing all that work.

I'd like to get involved in that, however these are my p=3D roblems:
- I have no running system that I could debug and
=3DA0 there= =3D by learn how GSM works.
-=3DA0 To=3DA0 get a running system I would need to implement a software
= =3DA0=3D =3DA0 only system, however, I cannot implement that without knowledge
=3D= A0=3D =3DA0 of GSM
=3DA0That is kindof a deadlock.

Therefore I wonder w= ea=3D ther the expert of GSM would share their
knowledge in the obove described way:
Having=3DA0
=3DA0 - a flow diagr= am=3D
=3DA0 - the etsi standard pages (or simple rewrites of it)
=3DA0 - the= h=3D tml parsed imlemention of a real TSM30 stack implement.
and linking that=3D all together to get a way for a newbie to
get started.
=3DA0

I think what makes OsmocomBB special is the very fact that we do not
have to rely on simulation, but can do the "real thing".

Nonetheleess, if somebody was interested in implementing what I've
described, I'd be more than happy to help any such project and
include the neccessary support in OpenBSC and/or OsmocomBB.
