Rakuten Symphony selects VIAVI for 5G Open vRAN

Global Japanese telecom Rakuten Symphony has chosen the VIAVI TM500 network tester to validate performance of its solutions from the lab to the field. The principal objective of this testbed is to maximise resolution of any issues in the lab in order to accelerate deployment at scale; it has been designed to simulate a city-wide network.

With over 85% of network equipment manufacturers using TM500 for gNodeB development, the VIAVI solution offers Rakuten scalability, stability, performance and fidelity to 3GPP specifications as implemented in live networks. Key features include: testing high numbers of 5G gNB carriers at system level; testing MIMO and carrier aggregation features; complex mobility, handover and I-RAT functionality between 4G and 5G; testing thousands of UEs over multiple carriers; and testing public warning systems and link adaptation features.
