Abstract
Research and development of the fifth generation (5G)
mobile networks has started strongly and European
Commission sees that "5G will be the very backbone of the
new digital economy." This report presents many example
research results obtained in VTT's innovation programme -
Critical technologies towards 5G - consisting of tens
projects. We start by presenting solutions for maximising
user experience in wireless service. Then, we study
enablers for improving system capacity including e.g.
spectrum sharing for both terrestrial and satellite
systems and millimetre wave radio technologies for 5G.
Next topic is energy efficiency of cellular networks
starting with consequences from thermal noise death of
Moore's law, and continuing with many solutions for
obtaining efficient heterogeneous cellular networks. Then
reliability of critical infrastructures is concentrated
on presenting first a tool for analysing
interdependencies between electricity distribution and
telecommunications networks in various fault scenarios.
In addition, we discuss physical layer security. This is
a new potential approach for defending against threats
and attacks in wireless networks. Finally, many network
technologies and environments used and developed at VTT
are discussed. For instance, details are given about the
5G test network project.
