About O-RAN Software Community (SC)
Who We Are
The O-RAN Software Community (SC) is a collaboration between the O-RAN Alliance and the Linux Foundation with the mission to support the creation of software for the Radio Access Network (RAN). The RAN is the next challenge for the open source community. The O-RAN SC plans to leverage other LF network projects while addressing the challenges in performance, scale, and 3GPP alignment.
Mission
Manage all software development, code storage, tooling, and developer integration testing aligned with the architecture specified by the O-RAN Alliance.
Vision
The telecom industry is experiencing a profound transformation, and 5G is expected to radically change how we live, work, and play. It’s critical to make network infrastructure commercially available quickly to ensure business success for operators. Turning to open source is one of the most efficient ways to accelerate product development collaboratively and cost-efficiently.
The O-RAN Software Community aligns with the O-RAN Alliance’s open architecture and specifications to achieve industry deployment solutions. Sponsored by the O-RAN Alliance, this new open source community under the Linux Foundation will develop modular, open, intelligent, efficient, and agile disaggregated radio access networks.
Get Involved
You can get started by joining the mailing list and Technical Oversight Community (TOC) meetings.
Project Scope & Goals
Software development, documentation, testing, and integration. Coordinate with related open source software projects and standards communities. Align with O-RAN architecture.
