Viavi Solutions has reported that the company successfully participated in a global O-RAN plug fest hosted by several Tier-1 communications service providers (CSPs) and the O-RAN ALLIANCE.
The plug-fest involved a series of on-site demonstrations in multiple countries. VIAVI provided industry-leading 4G and 5G test and validation platforms to support the worldwide event, which demonstrated key Open Radio Access Network (O-RAN) use cases involving several network equipment manufacturers (NEMs) and system integrators, accelerating the commercialization of O-RAN and diversification of the RAN supply chain.
“As a champion of interoperability test methodologies and the first company to introduce a comprehensive test suite for O-RAN specifications, VIAVI has worked closely with ecosystem partners and operators worldwide to help identify, isolate and resolve performance issues with disaggregated networks,” said Sameh Yamany, Chief Technology Officer, VIAVI. “The successful results of the global O-RAN ALLIANCE plugfest represent a significant step forward in the advancement of multi-vendor O-RAN environments, which are essential to scaling and sustaining 5G networks.”
In a multi-vendor based O-RAN environment, ensuring interoperability will become the network operator’s principal concern. The VIAVI Test Suite for O-RAN Specifications offers comprehensive, integrated solutions to validate that all interfaces are working correctly – including RF, signaling and interoperability, timing and synchronization – and equipment is performing to specifications even under load and stress.
In the lab, the TM500 and TeraVM families deliver UE, O-RAN subsystem and core network simulation to enable conformance, interoperability and performance testing of both complete base station and core network testing as well as wraparound testing of individual subsystems and core network elements.
