5G is more exhilarating than concerning. There are opportunities all over the map for the breadth of what we do
from simulation and design to characterization, validation, and
compliance testing. Perhaps a concern is the high rate of industry
consolidation during the midst of this generational change. 5G
is a major technology upheaval across the entire wireless supply
chain. In previous generational changes, the market has been
characterized by more than a handful of large players in each
sub-market with myriad smaller companies and startups involved
in a mix of enabling the larger players and challenging them to
think differently—a great recipe for innovation.
Designers face the following key issues: Living up to the hype,
new technologies for wireless realm, and physical realities in a
virtualized world. The 5G vision means orders of magnitude
improvement in all facets of network performance. Designers
must manage this with exceptional diligence to accomplish these
faster, shorter, bigger, and more efficient performance factors
and make it affordable. In addition, many designers of sub- 6
GHz radio systems are being asked to embrace carriers from
20 up to 90 GHz. The physics and practical ramifications are
new to the mainstream designers and we all have much to learn.
Lastly, the vision of virtualized and flexible networks shows
tremendous promise in business model, network efficiency, and
flexibility. There are profound barriers that exist in the physical
networks that must be overcome for the virtualized vision
to become real. Designers have their work cut out for them
to build hardware and software solutions to overcome these

5G will enable a whole range of new communications use cases, some of which may not even emerge until the full
potential of high-speed, low-latency connectivity is released.
5G standards have yet to be fully defined, but
it is clear that millimeter wave (mm Wave)
frequencies will be used to enable the very
high data rate applications. There is currently
a huge amount of development effort under
way to realize practical mm Wave systems
capable of allowing mobile devices to achieve
these promised high speeds. At the moment,
many different strategies and frequency bands
are under investigation. We believe that the
first commercial mm Wave 5G systems will
be in the region of 28 GHz, and the FCC is
supporting this band. Frequency bands around
37 and 39 GHz are also being promoted,
and it is likely that multi-band devices will
eventually be required.
Cell sizes for 5G will be much smaller than
for 4G, in all probability below 100m. Many
base station sites will therefore be required,
which could for example be located on lamp
posts. This densification is required not only
because of the difficulty of achieving non line-of-sight connections over longer distances at
higher frequencies, but also because if every
user is to receive a high data rate then there
will be a limit to the number of connections
each base station will be able to support. It also
means that urban areas will be first to benefit
