challenges of link-budget demands. Trials
suggest that at 3.5GHz, the difference between up-link and down-link is greater
than 16dB-this means more complex
designs using sophisticated MIMO
techniques and tremendous pressure on
low-noise and low power-consumption
designs. All need test solutions."
Thorpe and Helmick, Rohde & Schwarz:
"There are many challenges associated
with 5G. One of the biggest challenges
is the sheer flexibility. Features like subcarrier spacing, symbol duration, cyclic
prefix duration, bandwidth, frequencies
from 400 MHz to 43.5 GHz, and virtualized (core network) functions make 5G
incredibly complex. In order to fully test
5G, the test equipment also needs to be
incredibly flexible to reduce the need for
dozens of different test solutions."

Protecting 4G investments
Obviously, 5G is all the rage right now,
and will be for years to come. But with
the vast majority of us still operating
on 4G-or even 3G-connectivity until
the fifth generation of wireless communication is available, how are vendors
protecting their investments in 4G testand-measurement equipment?
Adnan Khan, senior business development manager at Anritsu Company:
"5G components, devices, and systems
must all be developed at an efficient
price point, which places a great deal

Sponsored by

of pressure on keeping cost-of-test low.
Fortunately, Anritsu's 5G test portfolio
has flexible platforms that have made
it efficient to upgrade current solutions.
This allows customers to protect their investment in existing test solutions and
upgrade to 5G NR support via software
in most cases. For example, we have developed 5G NR software options
for our Signal Analyzer MS269xA
series, Universal Wireless Test Set
MT8870A, and Signal Analyzer
M2850A."
Nichols, Keysight: "With modest
updates, 5G NR measurements
for FR1 can be made using many
4G-capable test solutions. There
are clearly new requirements that
drive architectural changes in test
equipment-these must with either the move to FR2, or the move
to much larger component carrier
bandwidths in 5G compared to
the 20MHz max in LTE-many of
these mean investments in new
platforms. Protecting investment here
comes in multiple forms: Our new 5G
capabilities must have legacy capability; and for products and solutions where
that does not make sense, then we must
ensure appropriate commercial terms-
like with our technology refresh terms."
Stasonis, Pickering: "This is where the
idea of a modular framework comes into
play. The modular infrastructure of our

product family (software, communications, hardware) is common, regardless
of the frequency spectrum in which a
customer is working. So as the demands
on the switching technology evolve as 5G
begins to be introduced into manufacturing, it is easy for a customer to adapt our
products to meet these needs."

5G NR FR1 and FR2.

AR RF/Microwave Instrumentation: "AR
takes its global support and service very
seriously. We want to provide the best
possible solutions and for those solutions to last for years to come. AR has
dedicated applications and service teams
providing these solutions. This includes
assisting customers through the buying
process and for continued support for the
life of their product."
Thorpe and Helmick, Rohde & Schwarz:
"R&S CMW500 customers can include 5G
NR NSA and SA test options simply by
adding a R&S CMX500 to the test setup.
The R&S CMW500 is an industry standard for LTE testing."

Luther, X-Microwave: "The analog RF is
where we support users today in extending the life of their test-and-measurement
investments. Any custom RF diagram can
be put together like LEGOs and used in
high-quality production test applications,
allowing a test engineer to fully customize their test set."
