O-RAN ALLIANCE Opens Call for Participation in its O-RAN Global PlugFest Fall 2025
O-RAN ALLIANCE Global PlugFest Spring 2025 Demonstrated Steady Evolution of the O-RAN Ecosystem
Since March 2025, O-RAN Work Groups and Focus Groups published 60 technical documents, bringing the total to 134 titles in current version and 830 documents overall. Four documents represent new titles.
On 24–25 April 2025, the 3GPP - O-RAN ALLIANCE joint workshop brought together experts from across the telecom ecosystem for a focused exchange on coordination for 6G. The dialogue aimed to avoid fragmentation and support aligned 6G development efforts.
This white paper explores advanced strategies to enhance energy efficiency in O-RAN based networks, building on existing techniques such as Cell and Carrier Shutdown and RF Channel Reconfiguration. It introduces innovative approaches for optimizing power consumption in key network elements, including Radio Units (O-RU) through dynamic voltage adaptation and renewable energy integration, and O-Cloud environments via intelligent workload management and energy-efficient Cloud Network Functions. Aligned with 3GPP Release-18 features like Discontinuous Transmission/Reception (DTX/DRX) and spatial power-saving methods, these strategies aim to substantially reduce energy consumption while maintaining high performance and service quality.
Central to these strategies are the intelligent capabilities of the O-RAN framework, particularly the Service Management and Orchestration (SMO), Non-Real-Time RAN Intelligent Controller (Non-RT RIC), and Near-Real-Time RAN Intelligent Controller (Near-RT RIC). Working in harmony, the SMO orchestrates resources across the network, the Non-RT RIC leverages rApps to develop AI/ML-driven long-term optimization policies, and the Near-RT RIC employs xApps to execute near real-time network adjustments. Together, these components provide a cohesive, intelligent framework that drives the dynamic and effective implementation of the energy-saving solutions detailed in this paper, positioning O-RAN as a leader in sustainable and efficient network operations.
It is important that 5G and next-G networks providing critical infrastructure and mission critical use cases are built with a Zero Trust Architecture (ZTA) to protect against external and internal threats. ZTA is the evolution of the zero trust concept to a concrete plan based upon multi-layered security controls that provide confidentiality, integrity, availability, authentication, and authorization protections from internal and external threats. The O-RAN ALLIANCE is committed to pursue a ZTA through stages of a maturity model that achieve a strong security posture to protect against evolving threats.
The USA Department of Commerce’s National Telecommunications and Information Administration (NTIA) awarded more than $273 million as part of the first batch of grants from the Public Wireless Supply Chain Innovation Fund’s second Notice of Funding Opportunity. This batch of awards will support projects focused on open radio unit hardware commercialization.

Join us for the O-RAN ALLIANCE Open Source Focus Group (OSFG) and University of New Hampshire Interoperability Lab (UNH-IOL) workshop on Open Source, bringing together projects and community participants from the end-to-end ecosystem (RAN-to-Core-Infrastructure), to promote alignment and integration between open source projects.
The purpose of the workshop is to reflect on the role of open source for O-RAN and to identify the necessary steps to revisit the O-RAN open source vision, strategy and roadmap and its relationship to other complementary and overlapping projects and communities.
Be part of this important and exciting discussion, shaping the role of open source software in Radio Access Networks and the O-RAN Ecosystem.
Join us for the O-RAN ALLIANCE F2F Meeting in Dallas, October 27-31, 2025!
Meet and work within the global O-RAN industry ecosystem, spanning MNOs, vendors, research institutions, academia, government agencies, and many more.
