Open RAN Solutions

Open RAN technology has gained traction with major deployments by Tier-1 service providers, increasing the need for subsystem and end-to-end conformance, performance, and interoperability testing, the joint statement said.

Energy Efficiency Testing

The majority of power in 5G networks is consumed by O-RAN radio units (O-RUs). To address this, R&S and Viavi have created an automated testbed to verify O-RU energy efficiency. This setup includes the R&S RTO6 oscilloscope, R&S NGP800 power supply, and Viavi TM500 O-RU Tester. The system tests energy efficiency under various load conditions and monitors power consumption dynamics accurately.

Scalable Testing Solutions

As O-RAN radios advance to commercial deployment, the focus has shifted to more extensive use case and functionality testing. R&S and Viavi said they offer a scalable solution with the R&S PVT360A vector signal analyser (VSA) and vector signal generator (VSG), combined with the Viavi TM500 O-RU Tester and Test Manager Application. This setup is designed for R&D teams requiring multiple test lines to speed up time to market.
