IC1004

This White paper states the view of the researchers of the European COST Action IC1004 on the future of Mobile Communications technology beyond 4G.
The future of Radio Access Networks is analysed in this paper under the assumption of three facts: wireless terminals will evolve to get any device connected, access networks are to change their architectural basis in the coming years, and spectrum usage strategies should be revisited to ensure the efficient connectivity of the coming massive wireless traffic scenarios.
As a result of such analysis, the paper identifies a list of relevant scientific challenges for the coming years.
