BONN, Germany, May 29, 2025 /PRNewswire/ -- The O-RAN ALLIANCE (O-RAN) today announced successful completion of the O-RAN ALLIANCE Global PlugFest Spring 2025.

O-RAN PlugFests are designed to accelerate the development of products and solutions based on O-RAN specifications by offering structured testing and integration opportunities in a neutral and collaborative environment.

At each O-RAN PlugFest, participants advance O-RAN-based technology and procedures for testing, deployment and operation of carrier-grade open, intelligent and virtualized Radio Access Networks (RAN).

Participants at the O-RAN Global PlugFest Spring 2025 demonstrated progress in diverse areas, including:

• Automated, cloud-native RAN deployment & testing
• AI-powered test automation with intelligent report analysis and automated test generation, enabled by Large Language Models (LLM)
• Intelligent RAN energy savings of 25 to 30%, enabled by rApps on Non-Real-Time RAN Intelligent Controller (Non-RT RIC)
• Intelligent network efficiency and service assurance, enabled by cell on-off switching rApp and xApp combined with traffic steering xApp
• Integration of open-source O-RAN components from multiple open-source communities in O-RAN networks
• Validation of transport network behavior under congestion and impairments for different deployment options
• E2E network performance testing in various scenarios
• Efficient cooperation enabling consistent and repeatable testing across labs and regions

O-RAN Global PlugFest Spring 2025 was hosted by 22 operators, Open Testing and Integration Centers (OTICs) and vendor-independent institutions. It took place in 8 venues and 19 labs around the world. It was conducted from February to May 2025 with a total of 69 participants, some of which participated at more than one venue.

"O-RAN Global PlugFests play a vital role in accelerating innovation built on O-RAN ALLIANCE specifications," said Chih-Lin I, Co-chair of O-RAN ALLIANCE's Technical Steering Committee and China Mobile Chief Scientist, Wireless Technologies, China Mobile Research Institute. "Each PlugFest showcases the steady evolution of the O-RAN ecosystem, highlighting progress across a wide range of technologies, solutions, and services that enhance RAN deployment and operations. It's particularly encouraging to see that the progress of O-RAN intelligence and automation capabilities has been gaining momentum. A big thank you to all hosts, labs and participants for their great efforts."

About O-RAN ALLIANCE
The O-RAN ALLIANCE is a world-wide community of mobile operators, vendors, and research & academic institutions operating in the Radio Access Network (RAN) industry. As the RAN is an essential part of any mobile network, the O-RAN ALLIANCE's mission is to re-shape the industry towards more intelligent, open, virtualized and fully interoperable mobile networks. The new O-RAN specifications enable a more competitive and vibrant RAN supplier ecosystem with faster innovation to improve user experience. O-RAN based mobile networks at the same time improve the efficiency of RAN deployments as well as operations by mobile operators. To achieve this, the O-RAN ALLIANCE publishes new RAN specifications, releases open software for the RAN, and supports its members in integration and testing of their implementations.
