VIAVI Solutions Inc. (VIAVI) (NASDAQ: VIAV) today introduced the TeraVM AI RAN Scenario Generator (AI RSG), the evolution of the company's market-leading RAN Intelligent Controller (RIC) Test platform. Maintaining all of the features of RIC Test, the AI RSG enhances the simulated system-level RAN behavior, creating a RAN digital twin that replicates real-world conditions in the lab. The AI RSG joins a test and optimization portfolio that is ideally suited to the needs of platform and application developers planning to bid for the National Telecommunications and Information Administration (NTIA) Public Wireless Supply Chain Innovation Fund (PWSCIF) Third Notice of Funding Opportunity (NOFO 3), which focuses on Software Solutions for Industry Verticals and Integration Automation.

The RIC uses artificial intelligence and machine learning (AI/ML) to autonomously manage radio resources with the aid of network data and native or third-party applications. Applications can be developed for specific industry verticals to tailor network functionality for more targeted use cases. The complexity of a multi-vendor open network is compounded by the presence of apps from different developers, making seamless performance a challenge.

AI RSG harnesses data obtained through Open RAN interfaces to train the RIC and r/xApps to generate quality-of-service improvements, industry-specific features and functionality, energy efficiencies and other value for network operators. It can simulate up to 10,000 user equipment (UEs) and several thousand cells (between 1,000 and 5,000) per reference server. It can be deployed in Docker containers within cloud environments or on dedicated servers. The scale depends on the specific use case, with the ability to generate data at various granularities, from one minute to daily intervals. The scalability matrix helps define parameters for different scenarios.
