Conversely, they are fully rewritable and can be adapted to various
mobile network operators.
As we have already seen, the demand for data is increasing
at a breathtaking rate. To meet this demand, experts are striving
to perfect the exploitation of 5G frequency bands. 5G uses
the so-called low-band and mid-band (FR1, < 7 GHz), together
with the very trendy high-band (FR2, >24 GHz), also called
" mmWave technology " . The use of the latter already constitutes
a huge push in the quest to meet bandwidth demand.
The checkmate, however, comes when these various bands are
combined in a process called carrier aggregation.
On top of interoperability and increased bandwidth capacity,
unlocking the full power of 5G for applications outside
mobile communication requires another pillar: private 5G
networks. Across markets and applications, enterprises are
increasingly in need of highly efficient, reliable, and secure
wireless networks. In terms of efficiency, there is no match for
5G and its unbeatable low latency. However, for a company to
base its critical operations on a network shared with others
constitutes a huge risk. First, the company does not have control
over the management of the network. Second, bandwidth
availability might fluctuate, compromising reliability. Third,
a shared network is at an increased risk of security breaches.
Alternatives to public 5G networks were therefore necessary
for the emergence of small revolutions such as Industry 4.0
(largely enabled by the Industrial Internet of Things, IIoT),
AR/VR, or widespread robotics. Private 5G networks were
born as an answer to that conundrum. Organizations build
their own networks and can do this according to two models
that involve very different financial outlays. The first is largescale
deployment, with the purchase of significant hardware
and allocation of large teams to manage it. The second is purely
cloud native, and is paid for per usage, in an " as-a-service "
setting. This second model gives access to private 5G networks
and their benefits to smaller companies - the user has the
final say.
Tomorrow's World
From these trends, we gather that tomorrow's world will be
largely enabled by advances in electronics in its broadest sense,
encompassing two main aspects: First, the electronics industry
moves at a variable but progressive rate of change, often leapfrogging
when enabled by significant progress in adjacent
fields of technology, e.g., the introduction of 5G and the services
that it has enabled.
Second, as previously mentioned, industrial problems of supply
have impacted these adjacent fields of technology, which
are critical and equally important to the success of the electronics
industry as a whole. The analogy of a chess board is useful in
explaining that each piece moves forward, yet you need all the
correct pieces to win the game and see truly inspiring changes
in the electronics industry. Post-crisis, we are now on the cusp
of these breakthroughs.
