5G Broadcast/Multicast evolves:
in China AIB builds new business opportunities cont'd...
while testing this new technology.
The aim of the test run is to validate
the transmission technology in terms
of its operability and market potential.
While running the two POCs in Beijing
and Rio de Janeiro, Rohde & Schwarz
believes that 5G broadcast has a future
in Europe as well, where it supports
CRIT (RAI Center for R&D) in Torino,
with a testing network including high/
medium power transmitters and the
Broadcast Service and Control Center
(BSCC) playing the role of the core
network.
China builds on 5G Broadcast
to create new technology
horizons with AIB
Beijing is a city witnessing the
start of another big 5G Broadcast/
Multicast project. The Academy of
Broadcasting Science (ABS) and China
Broadcasting Network (CBN), the two
public institutions under governmental
authority of the Chinese National Radio
and Television Administration (NRTA),
have set up a proof-of-concept (POC)

trial, which started in August 2019.
That date marked the first step of the
long-term strategies pursued by both
parties, which comprise 5G broadcast
commercial deployment by the 2022
Winter Olympic Games in Beijing,
followed by further national expansion
by the 2025.
Further to this proof of concept
trial, the Chinese technical standards
organizations are preparing a new
mobile Broadcast/Multicast standard
named AIB: Advanced Interactive
Broadcast that will be considered
as the future industry standard. It
is based on FeMBMS/5G Broadcast
standardized in 3GPP Rel.16 which will
be ready by end of this year.
The Radio Access Network will be
similar to 5G Broadcast, as defined in
3GPP Rel.16 and the core network will
be enhanced and simplified
The AIB working group includes
more than 70 members, such as Nokia,
Ericsson, Samsung, Huwaei, ZTE,
Qualcomm and Rohde & Schwarz.
The group's strategy is to support

mobile and broadcast convergence
within a 5G technology environment
where Point-to-Point communications
utilize the existing 5G standard.
Regarding
Point-to-Multipoint
communications,
the
group
is
innovating to meet Broadcasters'
requirements, converged within Sub700MHz frequency for commercial
deployment.
Already, AIB has trials operating
across China. Its target is to roll out
the first commercial deployments
in 2022 with large scale commercial
service roll out in 2025.
AIB is composed of 12 standards
defining the main requirements for
frequency resources and network
elements, such as transmitters in the
RAN and the Broadcast/Multicast Core
network.
The Broadcast world is watching
China with keen interest. All the
countries that are either involved in
trials or interested in 5G Broadcast/
Multicast with R&S are watching the
development of AIB closely.

In Europe, this includes Germany,
France, Spain, UK, Italy, Austria,
Finland, Russia and Switzerland.
In the Middle East and Africa, UAE
and South Africa are interested,
and further afield, Australia, India,
Malaysia, Philippines, Hong Kong,
Taiwan, Korea and Japan are all
keeping tabs on AIB's evolution.
In the Americas, Brazil, Colombia,
Mexico and USA all see potential
applications for AIB in their own
countries.
5G multicast is still an embryonic
technology, but it is exhibiting the
ability to transform the mobile
entertainment
and
information
market. China's AIB concept builds on
much of the pioneering development
work of 5G and has the potential
to open up major new markets
across China and also in many other
countries.
Today's trials will be tomorrow's
commercial pioneers - the big winners
will be the early adopters.
