VIAVI releases 2021 updates for O-RAN test suite

1 min read

Viavi Solutions has released updates to its industry-first Test Suite for O-RAN Specifications.

The O-RAN ALLIANCE’s specifications for open radio access networks are being adopted by operators and equipment manufacturers worldwide, to reduce infrastructure costs and lower the barrier to entry for new product innovation.

The test suite has been augmented to include use cases of critical importance as O-RAN becomes adopted at scale, as well as learnings from customer engagements around the globe.

In a multi-vendor based O-RAN environment, operators will bear the burden of ensuring conformance, interoperability, and performance.

Based on its position validating network products, VIAVI has a comprehensive O-RAN test platform, and is active in specifications development, as the editor of interoperability test specifications in the open fronthaul (WG4) and open interfaces (WG5) working groups, and the co-chair of multiple working groups at the O-RAN ALLIANCE.

VIAVI has developed partnerships with complementary solutions from an extensive range of vendors.

Updates to the Test Suite include:

  • O-RAN Subsystem and End-to-End Testing – proving O-RU conformance, performance and interoperability to network operators; performance and interoperability validation of open fronthaul in the lab and field; validating the O-DU in a multi-vendor O-RU environment; validating F1 interface performance using an O-DU emulator; RAN Intelligent Controller and xApp mixed vendor ecosystem assurance; and end-to-end network performance, mobility and capacity test
  • Transport Network Testing – verification of 4G and 5G fronthaul transport and synchronization networks
  • Network Assurance – operational assurance, troubleshooting and optimisation.

“The promise of O-RAN extends beyond the many benefits of an open ecosystem to include a solid foundation for virtualized network elements, enabling increased speed and scalability to capture the burgeoning 5G market,” said Sameh Yamany, Chief Technology Officer, VIAVI. “Yet the complexity of multi-vendor O-RAN architecture presents significant challenges for successful network development, deployment and operation, requiring thorough validation, integration and troubleshooting with a complete set of advanced test solutions.”
