The O-RAN Software Community (SC) Documentation.
Welcome to O-RAN SC H Release Documentation Home
O-RAN Alliance (https://www.o-ran.org/) members and contributors have committed to evolving Radio Access Networks (RAN) around the world. Future RANs will be built on a foundation of virtualized network elements, white-box hardware and standardized interfaces that fully embrace O-RAN’s core principles of intelligence and openness. An ecosystem of innovative new products is already emerging that will form the underpinnings of the multi-vendor, interoperable, autonomous RAN, envisioned by many in the past, but only now enabled by the global industry-wide vision, commitment and leadership of O-RAN Alliance members and contributors.
O-RAN SC is partnering with the O-RAN Alliance and Linux Foundation to support the software development for an open RAN solution that is available to everyone. The community will align with the architecture and specifications that are created in the O-RAN Alliance working groups to create a working software solution to enable an open and intelligent 5G RAN.

O-DU Low H Release Feature Scope:
The O-DU Low H release is the same as the F Release and G Release that added support for Massive MIMO, URLLC and it is based on the commercial FlexRan 21.11 release.
The O-DU Low H, G and F Release code is an Intel contribution in collaboration with Tieto Poland for the source code releases in the O-RAN gerrit and for the binary blobs contributed via GitHub.
For the documentation preparation of the H, F and G release Intel worked with collaboration from Fransiscus Bimo and Professor Ray-Guang Cheng from National Taiwan University of Science and Technology (NTUST).
The H, G and F release are being used for end to end testing and it is based on the E maintenance release that was used for the 2021 November US O-RAN Plugfest and tested in conjuction with 2 stack partners and 2 different Test equipment vendors. The Front Haul Interface was also tested for compliance using Keysight’s Front Haul Test equipment.
