CHANDLER, Ariz., May 22,
2024 /PRNewswire/ -- Rohde &
Schwarz (R&S) and Viavi Solutions Inc. (VIAVI)
(NASDAQ: VIAV) today announced an expansion of their
partnership for joint wireless lab test solutions. The two
companies, leaders in wireless communication test and active in
standards development, continue to address critical requirements
based on new 3GPP and O-RAN specifications. Since the launch of
this partnership, Rohde & Schwarz and VIAVI have established a
reputation for compact, flexible solutions drawing from the
strengths of both companies while delivering a seamless user
experience.
Open RAN
With several major deployment announcements
by Tier-1 service providers, Open RAN has entered the mainstream of
network infrastructure. While subsystem and end-to-end conformance,
performance and interoperability remain critical, test needs have
grown.
Network Energy Saving. O-RAN radio units (O-RU)
consume the majority of power in 5G radio access networks. Network
equipment manufacturers and service providers are prioritizing O-RU
energy efficiency without sacrificing performance. Rohde &
Schwarz and VIAVI have developed a fully automated testbed to
verify O-RU energy efficiency, including the R&S RTO6
oscilloscope, R&S NGP800 power supply and the VIAVI TM500 O-RU
Tester. The TM500 O-RU Tester emulates the DU, synchronizes and
configures the O-RU and offers several test scripts to verify O-RU
energy efficiency under different load conditions. The R&S
equipment can then monitor dynamic device activities versus power
consumption: The oscilloscope monitors energy dynamics under
various traffic conditions by tracking power changes over time,
while the power supply – besides powering the O-RU – also provides
high measurement resolution and accuracy over a long period of
time. The VIAVI O-RU Test Manager Application ensures a seamless
user experience across the testbed.
Test Scalability. As O-RAN radios move to commercial
deployment, development testing needs to move beyond lab validation
of conformance to greater use case and functionality testing within
R&D. These newer use cases prioritize simplicity, speed and
cost effectiveness in testing. The R&S PVT360A is a compact,
single-box vector signal analyzer (VSA) and vector signal generator
(VSG) that combines with the VIAVI TM500 O-RU Tester and VIAVI O-RU
Test Manager Application for a more scalable solution, providing a
cost-optimized and simpler setup that is well-suited for R&D
teams that require multiple test lines to accelerate time to
market.
Non-Terrestrial Networks
Satellite operators, mobile
network operators, equipment vendors and end-user application
providers need to be able to evaluate the performance of NTN
networks and the traffic that runs across them. To support a
variety of use cases, Rohde & Schwarz and VIAVI have developed
an NTN digital twin testbed covering Low Earth Orbit (LEO), Medium
Earth Orbit (MEO) and Geosynchronous Orbit (GEO). Use cases include
validating end-to-end connectivity and performance; measuring
Quality of Service over large coverage areas with different types
of UEs; end user application performance while coping with
distance, speed and mobility of both satellite and UE; and
reliability and stability. The testbed includes:
- The R&S CMX500 mobile communication network tester, with
channel emulation and fading in a single box, including all 3GPP
fading profiles
- The VIAVI TM500-AS2, a streamlined version of the flagship used
by global network equipment manufacturers for base station testing,
fully supporting the 3GPP protocol including Doppler and delay
pre-compensation
- The VIAVI TeraVM Real Data Applications (RDA) engine, enabling
rich and realistic application and traffic scenarios to test system
performance under varying conditions.
"It feels great to work with experts," said Alexander Pabst, Vice President Market Segment
Wireless Communications at Rohde & Schwarz. "Combining our
market leading products to create solutions that address our
customers' problems in smart ways. Energy efficiency tests hit the
nerve of the industry, and our smaller footprint setup meets the
needs of new segments that are popping up left and right of
conformance. In addition, I am extremely pleased to see our
collaboration expanding into space with the most compact digital
twin solution for NTN. Here, not even the sky is the limit!"
"Since we introduced joint O-RU conformance testing, R&S and
VIAVI have been delivering on our vision of best-of-breed approach
with a unified customer experience," said Ian Langley, Senior Vice President and General
Manager, Wireless Business Unit, VIAVI. "We are pleased to expand
our partnership into new areas of demand, as O-RAN equipment enters
commercial deployment and evolution, and the industry incorporates
NTN to augment coverage in mobile communications."
