INDUSTRY UPDATE
O-RAN specifications have matured significantly, and open, cloud-native design is now a baseline expectation!
The focus for 2026 and beyond is on consolidation of O-RAN specification work for updating EXISTING 5G NETWORKS. Learn more here.
INDUSTRY UPDATE
AI-driven network intelligence is moving from experimentation to industrial-scale deployments!
Hear from leading operators and vendors discussing where they stand in their shift toward AI-native RAN.
INDUSTRY UPDATE
Multiple operators are “getting their hands dirty” deploying O-RAN-based networks!
At the MWC26 O-RAN ALLIANCE Summit, operators openly spoke about where they stand in their RAN transformation journeys.

What We Do
O-RAN
Specification
Effort
O-RAN specifications are enabling a broad industry ecosystem. Defining the complex
O-RAN
Architecture is a step-by-step process resulting in hundreds of technical documents.
Companies of different sizes and specializations can use O-RAN Specifications to create their innovative and competitive open solutions.
Access O-RAN specifications
Open
Source
Software
O-RAN specifications serve as a basis for open software reference design.
The O-RAN Software Community hosts developers brought in by many
O-RAN
players, cooperating on tens of software projects.
During 2026, the O-RAN Software Community is being migrated under the Linux Foundation Networking umbrella.

Testing,
Integration
& Certification
O-RAN Global PlugFests are periodic events organized and co-sponsored by O-RAN ALLIANCE to enable efficient progress of the O-RAN ecosystem through well-organized testing and integration. Vendors and providers come together to test, evaluate and verify their products and solutions.
Learn about O-RAN PlugFests
The O-RAN Certification and Badging Program ensures confidence in O-RAN products. Open Testing and Integration Centres (OTIC) provide a collaborative and neutral environment, and are qualified to issue O-RAN Certificates and Badges.

Aligned with the Industry
The O-RAN architecture and specifications build on common RAN standards. Standards Development Organizations (SDOs) and industry bodies align with O-RAN ALLIANCE to avoid fragmentation or duplication of efforts. O-RAN specifications are being transposed to regional standards by ETSI, ATIS and TTA.
O-RAN ALLIANCE is working with 3GPP to coordinate efforts towards a unified vision for 6G.
3GPP
ETSI-MSG adopting O-RAN specifications
through the PAS process
ETSI-ZSM for cooperation on automation
and orchestration
ETSI-NFV for cooperation virtualized
