These “IMT-2020” systems will enable
wireless communication to match the speed and reliability achieved by
fibre-optic infrastructure, ITU said in a report.
The potential application fields of
IMT-2020 systems, in addition to voice and video, span from health care
to industrial automation, virtual reality, automated driving, and
robotic systems controlled with an imperceptible time lag.
One-millisecond end-to-end latency is
necessary for technical systems to replicate natural human interaction
with the environment, a goal that experts say should be within the reach
of future networks.
In 2012, ITU established a programme on
International Mobile Telecommunications for 2020 and beyond, which
provides the framework for IMT-2020 research and development worldwide.
ITU’s Radiocommunication Sector is coordinating the international
standardisation of IMT-2020 systems. ITU-T is expected to play a similar
convening role for the technologies and architectures of wireline
networks.
ITU
Secretary-General, Houlin Zhao, was quoted in the report as saying
that, “Air interfaces and radio access networks are progressing rapidly,
but there is a need to devote more attention to the networking aspects
of IMT-2020. Wireline communications will transform significantly in
support of IMT-2020, and the coordination of ITU’s standardisation and
radiocommunication arms will ensure that the wireline and wireless
elements of future networks develop in unison.”
The Director of the ITU
Radiocommunications Bureau, François Rancy, was also quoted as saying
that, “Following on from the successful development of IMT-2000 and
IMT-Advanced, the standards for all of today’s 3G and 4G mobile systems,
the work to be carried out by ITU-T on the network aspects will be an
important complement to the activities undertaken by ITU-R in developing
the radio interface standards for IMT-2020.”
The Director of the ITU Telecommunication
Standardisation Bureau, Chaesub Lee, said, “Today’s network
architectures cannot support the envisaged capabilities of IMT-2020
systems. Innovation in standardisation is essential across core
networks, access networks, virtualised data clusters and masses of smart
networked units. Moving beyond convergence, the concepts underlying
networking must evolve to support the development of integrated
fixed-mobile hybrid networks.”
The Head of 5G Research and Development
at Huawei, Wen Tong, also said, “5G will power a wide range of new user
experiences, but the bottleneck remains the speed of the network.
Everyone in the ICT ecosystem needs to work together. This is the most
important condition for us to realise 5G, and this is the reason Huawei
is contributing to ITU’s efforts to consider what the road to 5G demands
of all parts of the ecosystem.”
The new Focus Group, which is open to
participation by any interested party, will provide the launching point
for ITU-T’s contribution to IMT-2020 standardisation. The group will
follow an intensive work plan to complete its study prior to the
December meeting of ITU’s standardisation expert group responsible for
future networks, cloud computing and network aspects of mobile
communications, ITU-T Study Group 13.
