Empowered by principles of intelligence and openness, the O-RAN Architecture is the foundation for building a virtualized RAN on open hardware and cloud, with embedded AI-powered radio  control.


What We Do



O-RAN specifications and open software are enabling a broad industry ecosystem. Companies of different sizes and specializations can use them to create their innovative and competitive open solutions.

Defining the complex O-RAN Architecture is a step-by-step process resulting in hundreds of technical documents.

Access O-RAN specifications


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.

Testing & Integration

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.

O-RAN has been widely adopted by the industry

Mobile network operator commitment


Alex Jinsung Choi

Chairman of the O-RAN ALLIANCE

and SVP Strategy & Technology Innovation, Deutsche Telekom

"The O-RAN ALLIANCE has rapidly grown from the five founding mobile operators to a broad community of operators and contributors comprising industry leading large vendors, small & medium companies, start-ups and academic institutions. We are proud to welcome such a diversity of members in our joint effort to lead the industry towards next generation open and smart RAN."

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 adopted by ETSI, illustrating the global move towards O-RAN and advancing the O-RAN ALLIANCE’s mission.
