5G TEST

" 5G NR defines a very flexible air
interface and is using beamforming
techniques by default. "

TSME6 universal network scanner, in conjunction with the
ROMES drive test software, now allows EMF measurements
based on 5G NR signal components, like the 'always-on' synchronization signal blocks (SSB). Any service provider can now,
while doing network optimization, also measure the current
exposure to electromagnetic fields. "

- Andreas Roessler, Rohde & Schwarz
Rohde & Schwarz has been addressing increased public interest in human exposure to electromagnetic fields. The company
develops and provides test and measurement products that help
to ensure that exposure is below a certain threshold defined by
authorities and local regulators, according to Andreas Roessler,
technology manager at Rohde & Schwarz USA. " As a company, we
follow here the guidelines set by the International Commission
on Non-Ionizing Radiation Protection (ICNIRP), which defines
several measurement principles, based on frequency range and
exposure time, " he said. " 5G NR defines a very flexible air interface and is using beamforming techniques by default, which
makes the EMF measurements more challenging and complex. "
Many regulators require a measurement of the EMF exposure
per radio access technology, thereby requiring more sophisticated methods than a single spectrum scan, Roessler explained.
" Due to those enhanced requirements, we now also offer EMF
measurement capabilities embedded in our test solutions for
network optimization and benchmarking, " he said. " The R&S

MathWorks provides a suite of tools for 5G design and test, according to Dr. John Wang, principal wireless industry manager.
He cited two capabilities that are particularly useful for 5G test:
5G waveform generation and connectivity to SDR hardware and
RF instruments.
" Let's start with a closer look at the first capability, " Wang said.
" MathWorks products include a waveform generation app that
can generate standard-compliant 5G waveforms in addition to
several other standard waveforms (LTE, WLAN, etc.). This app
boosts productivity for RF test engineers because it makes all the
options on an RF instrument available in the graphical interface. "
He noted that while MathWorks has had the ability to generate
waveforms programmatically for years, the new app can supply
a real signal generator with standard-compliant 5G signals, with
the generated waveforms used over the air, with test and measurement instruments from various hardware vendors.
