Viavi joins the OpenAirInterface software alliance as strategic member

Viavi Solutions Inc. has announced it has joined the Strategic Board of the OpenAirInterface Software Alliance (OSA). Viavi participation adds a test equipment provider to the OSA board and opens a new chapter in the relationship that OSA maintains with the O-RAN ALLIANCE and the open RAN stakeholders. This also marks a significant milestone in advancing open-source initiatives within the telecommunications industry.

OpenAirInterface (OAI), known for its pioneering efforts in open-source software for 4G and 5G networks has recently assumed a key role in the path towards multivendor open RAN solutions by providing its O-CU and O-DU software for interoperability with the O-RUs from the industrial partners. This role, visible in O-RAN plugfests and other reference design showcases, is expected to significantly advance through this engagement with Viavi, as a professional testing company’s software can be constantly leveraged to improve the quality of the OAI open source components.

For over 100 years, Viavi has been directly involved in testing, assuring, and securing the largest communications networks around the globe, and validating network products for all Tier-1 network equipment manufacturers. The company plays an active role in specifications development across 3GPP, O-RAN ALLIANCE, and TIP. Viavi has participated in every global Open RAN PlugFest, providing benchmarking and validation, and now offers the most comprehensive test suite in the industry, including lab validation, field deployment, and service assurance.

OSA welcomes Viavi as a valuable contributor to its mission of fostering innovation and collaboration in developing next-generation wireless technologies.

As a global leader in network testing, monitoring, and assurance solutions, Viavi brings unparalleled expertise and resources to the OpenAirInterface community. Their commitment to advancing network technologies aligns seamlessly with the Alliance’s goals of promoting openness, interoperability, and standards-based approaches in the telecommunications ecosystem.

With Viavi ‘s support, OpenAirInterface aims to accelerate the development and adoption of open-source solutions for 5G networks, driving greater agility, scalability, and cost-effectiveness in deploying wireless infrastructure worldwide.
