Data tracked by StockTitan Argus on the day of publication.
The two companies offer:
O-RU Conformance Test. Fronthaul conformance tests, defined by the O-RAN ALLIANCE, ensure that O-RUs are interoperable with the O-RAN distributed unit (O-DU). The joint test solution includes:
- The R&S SMW200A vector signal generator, R&S FSVA3000 signal and spectrum analyzer and the R&S VSE signal analysis software from Rohde & Schwarz, to emulate a real-world radio environment by generating, capturing and analyzing RF signals, extended for O-RAN applications.
- The TM500 O-RU Tester from VIAVI, implementing the O-RAN Distributed Unit (O-DU) side of the M-plane and C/U-plane functionality necessary to configure the interface with the O-RU and exchange of I/Q data over the Open Fronthaul.
- The O-RU Test Manager application, providing a single point of control for the integrated system, simplifying testcase workflow while allowing deeper data inspection and analysis as needed.
The same set-up can be also used for performing conformance cases defined by 3GPP TS 38.141/36.141 for 5G/LTE base stations (BS).
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. The TM500 O-RU Tester can also be scaled to provide direct performance testing such as uplink and downlink data performance and capacity testing.
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 O-RU Test Manager Application ensures a seamless user experience across the testbed.
"Our joint O-RU conformance test solution has been used to test a wide range of different O-RUs at global plugfests of the O-RAN ALLIANCE over the last years. It has a solid presence at Open Testing and Integration Center (OTIC) labs worldwide and was instrumental in initial O-RU certifications in
"Rohde & Schwarz and VIAVI are proud to support the NTIA Open RAN Innovation and Commercialization based on our best-of-breed approach with a unified customer experience," said Ian Langley, Senior Vice President and General Manager, Wireless Business Unit, VIAVI. "Since we first began offering O-RU conformance testing, open radios have advanced significantly, and test requirements – from scalability for use across the development cycle, to energy saving, have become critical. We are pleased to expand our partnership into these new areas."
