The latest report from GSA shows, by the end of May 2020, 386 operators globally had announced they were investing in 5G, , among which 81 operators in 42 countries/territories launched 5G commercial services, including the most recent MTN 5G launch in South Africa.
5G, the fifth
generation of mobile networks, will enable enhanced mobile broadband, mission-critical
communications, and massive Internet of Things (IoT) communications between
the immediate need is for online, digital communications, which can easily be
provided by 4G or LTE networks.
The good news
is that LTE is also the foundation for the revolutionary move to 5G.
digital divide and empowering more of the world’s people with online
connectivity is key to overcoming poverty and attaining a sustainable future.
This will require constantly expanding LTE (4G) mobile broadband coverage and
working online is becoming acknowledged as a human right. Sadly, billions of
people remain excluded from the opportunities of the online economy, according
to Emmanuel Coelho Alves, Senior Marketing Director at Huawei.
“There is a
need to redouble our effort for more digital transmission and inclusion to
support United Nations Sustainable Development Goals (SDGs), and bring the
excluded 3.9 billion of world’s population online,” he said, “It won’t be easy,
but with cross-sector efforts from government and partners in the private
sector, academia and civil society … we can achieve that.”
speaking at the recent online LTE Summit 2020 held by the Global System for
Mobile Communications (GSMA).
Alves said that
there had been progress in expanding global mobile broadband coverage, with
almost 66% of areas now covered. Of these, 90% had access to high-quality
networks such as 3G and 4G.
Around 80% of
the world’s population now has mobile coverage, according to the latest GSMA report. Of these,
more than 50% of connections are already on 4G.
Africa, there are 456 million unique mobile subscribers, representing 44% of
people, with this proportion expected to grow to 50% by 2025.
The GSMA report
predicts that Africa will be the fastest-growing global region, with a compound
annual growth rate of 4.6%. However, mobile broadband subscriber numbers remain
significantly lower, with 239 million subscribers and a penetration rate of
Africa’s people into the mobile economy will require ongoing expansion of
mobile broadband services such as 4G, with penetration expected to reach 39% by
“4G provides an
extremely good asset when you go later to 5G,” said Alves. “4G has been
deployed widely in the past years. 4G is the capacity layer in city, leveraging
massive MIMO (multiple-input and multiple-output) in hot spots with significant
By applying a
standard known as ENDC (E-UTRAN New Radio – Dual Connectivity), network
operators are able to use both 4G and 5G schedulers together.
It is also
possible to use a technology known as DSS (dynamic spectrum sharing) to allow
for real-time allocation of spectrum resources between 4G and 5G, depending on
network traffic. This can be achieved with millisecond accuracy.
is the main mobile broadband layer, and what is replacing 3G,” said Alves. “But
on top of this, 4G has flexible capabilities that allow 4G and 5G to work
together from the network level.
Industry leaders believe that
in the medium term, 4G will be the layer of choice for global mobile
communications, while 5G will mainly be used in more industrial communications.
networks already have the capabilities to guarantee an optimal user experience
for 5G users, including services such as virtual reality, augmented reality,
and cloud gaming.
It thus makes
sense for national networks to invest in 4G to secure future growth
opportunities, while already supporting leading-edge 5G capabilities.
Madkour, VP of global wireless networks marketing and solutions at Huawei, said at the AfricaCom 2019 conference in
Cape Town last year, that “all investment in expanding 4G and organising site
assets will reduce the amount of money needed to switch on 5G in the near
future. Every rand spent on 4G is thus a rand invested in 5G.”
Whether seen from
a network operator or a policy perspective, 4G is thus not simply an interim
step towards 5G. The 4G foundation already heralds the arrival of our 5G
