Hello,
I found some english lectures about communication by university Freiburg
(germany) as video:
http://itunes.uni-freiburg.de/uebersicht/podcast_content?id_content=48
e.g.
Protocols and technologies of telephone networks
ISDN network functions, introduction to GSM digital mobile
Extension of GSM overview
GSM data services
UTMS as the world wide 3G mobile standard
You can watch it online as flash or download a .mp4 file :)
