Rohde & Schwarz and Viavi Solutions yesterday announced an expansion of their partnership for joint wireless lab test solutions. The two companies 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.
With regard to Open RAN, 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 VIAVI O-RU Test Manager Application ensures a seamless user experience across the testbed.
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.
Alexander Pabst, Vice President Market Segment Wireless Communications, Rohde & Schwarz
It feels great to work with experts. 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!
Ian Langley, Senior Vice President and General Manager, Wireless Business Unit, VIAVI
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. 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.
