O-RAN ALLIANCE announces Release 002, new specifications and 2022 Global PlugFests


Release 002 of the O-RAN Minimum Viable Plan

In 2021, the O-RAN ALLIANCE introduced a new initiative that describes how their specifications will be combined to form the first version of the O-RAN Minimum Viable Plan. This plan provides the specifications needed for the open RAN ecosystem to develop products that meet the needs of the highest priority operators.

O-RAN Release 001 focused on creating open interfaces spanning open fronthaul, transport, hardware and cloud.

The new O-RAN Release 002 focuses on enabling Open Intelligence. Features in Release 002 include specifications for traffic steering, quality of service and quality of experience optimization, RAN slicing, and service management and orchestration.

40 O-RAN specifications published since November 2021

O-RAN ALLIANCE has published further technical specifications for open and intelligent RAN. 4 new specification titles include:

  • O-RAN R1 Interface: General Aspects and Principles v1.0

  • O-RAN A1 Interface: Test Specification v1.0

  • O-RAN Acceleration Abstraction Layer High PHY Profile v1.0

  • O-RAN Security Test Specifications v1.0

Another 36 technical documents have been updated with enhancements and new features. To learn more about the new and updated specifications, please read our web announcement. To access the O-RAN specifications, please visit our website.

Two O-RAN Global PlugFests planned for 2022

Building on the successful O-RAN Global PlugFest 2021, the O-RAN ALLIANCE plans to organize two global PlugFests for its member companies and institutions in 2022. Offering two PlugFests will better reflect the growing work on the integration and commercialization of the O-RAN solutions.

First O-RAN specification submitted to become ETSI Publicly Available Specification (PAS).

Throughout 2021, the O-RAN ALLIANCE expanded its interactions with other industry bodies and standards development organizations. For example, the first O-RAN specification – the O-RAN Fronthaul Control, User and Synchronization Plane Specification – has been submitted for possible adoption by the ETSI Technical Committee Mobile Standards Group as part of the ETSI PAS process. More O-RAN specifications are planned for future submissions to the ETSI PAS process.


The O-RAN ALLIANCE is a global community of more than 300 mobile operators, vendors, research and academic institutions working in the Radio Access Network (RAN) industry. With the RAN being an integral part of any cellular network, the mission of the O-RAN ALLIANCE is to transform the industry towards smarter, open, virtualized and fully interoperable cellular networks. The new O-RAN specifications will enable a more competitive and vibrant RAN supplier ecosystem with faster innovation to improve user experience. O-RAN based cellular networks will simultaneously improve the efficiency of RAN deployments as well as operations by cellular operators. To achieve this, the O-RAN ALLIANCE publishes new RAN specifications, publishes open software for the RAN and supports its members in integrating and testing their implementations.
