I don't quiet understand your question... are you talking about like a development road for the new communication systems?
I think in any technology there is not like a road map to develop new techs... but there are big objectives or tendencies qhere the aim to.
In communication is easy, faster, safer, more reliable communication systemes. Mobility is taking a lot of field too, cost eficient solutions, bigger bandwith.... To mention some "roads" telecommunication is taking...
Hope it helped
