Ericsson Joins Open Network Foundation

The OCUDU Ecosystem Foundation is a public-private partnership with backing from the U.S. Department of War, aiming to create a "Linux of RAN." This initiative seeks to develop an open-source, carrier-grade software stack for the core of the Radio Access Network, specifically the Centralized Unit (CU) and Distributed Unit (DU). The goal is to foster a more resilient and adaptable telecommunications ecosystem, with dual-use applications for both commercial 5G and military defense needs. Ericsson's role as a founding premier member will be to provide architectural guidance and ensure the technology remains neutral, building on its experience with global network deployments. This move aligns with Ericsson's broader strategy of championing open-source solutions and its significant involvement in other Linux Foundation networking projects. The foundation's software will be built upon the existing srsRAN project, a mature and field-proven open-source platform. The initial software release is slated for March 2026, with subsequent releases planned every six months over a two-and-a-half-year period to introduce advanced capabilities like massive MIMO and support for non-terrestrial networks. This collaboration brings together a wide range of industry leaders. Other founding premier members include AMD, AT&T, DeepSig, Nokia, NVIDIA, Softbank, SRS, and Verizon. The initial development of the OCUDU software was funded by the National Spectrum Consortium and the FutureG Office, awarded to AI-native wireless company DeepSig and Software Radio Systems (SRS). The OCUDU initiative is seen as a way to accelerate innovation in 5G and the development of 6G by creating a common, open platform for developers. This approach is intended to lower the barrier to entry for new telecom suppliers and allow for the rapid prototyping and integration of new network features. This move toward open architecture is also reflected in Ericsson's other major partnerships. Notably, Ericsson has a multi-billion dollar deal with AT&T to deploy Open RAN in the U.S., with a goal of having 70% of AT&T's wireless network traffic on open-capable platforms by late 2026. The OCUDU project aims to address challenges in the current Open RAN landscape, where the CU and DU layers have largely remained proprietary. By creating an open and interoperable ecosystem, the foundation hopes to move beyond closed systems and foster a more competitive and innovative wireless industry. The involvement of the U.S. Department of War underscores the strategic importance of this initiative for national security. The goal is to enable the rapid development of networks that can "establish dominance in battle and the global economic landscape."
