Foreword

As we approach 2020, one of the most important
areas of ITU work will be our international
standardization of IMT-2020 (5G) systems. ITU is
supporting the development of a 5G environment
where we will all have access to highly reliable
communications; where trusted ICTs will be core to
innovation in every industry sector.
Alongside enhanced mobile broadband and the
Internet of Things, 5G will support ultra-reliable and
low-latency communications for applications such
as automated driving, remote medical surgery,
collaborative robotics and advanced virtual reality.
At this high end of 5G application, in some cases we
will demand end-to-end latencies as low as
1 millisecond.

What becomes evident when looking at the
ambitious performance targets of 5G systems, and
the wide variety of envisioned 5G applications, is
that future networks will need to be agile all-round
players able to perform a wide array of specialized
functions.
5G will make no compromises when it comes to
performance. Every application must be able to
perform to its full potential and this will demand
significant innovation in network architectures and
orchestration techniques. In May 2015, ITU The success of the Focus Group was in large part
