Ericsson Joins New US Open RAN Foundation

Open Radio Access Network (Open RAN) technology shifts network design away from single-vendor proprietary systems. It enables mobile network operators to use components from various suppliers by creating standardized, open interfaces between the radio, hardware, and software. The OCUDU initiative specifically focuses on creating open-source software for the Centralized Unit (CU) and Distributed Unit (DU), which are key computational parts of the base station in a RAN architecture. The project originated with funding from the National Spectrum Consortium awarded to AI-native wireless company DeepSig and software developer Software Radio Systems (SRS). Ericsson's deeper involvement in open standards follows a landmark $14 billion multi-year Open RAN contract with AT&T in 2023. As part of that deal, AT&T is transitioning its network, with a goal to have 70% of its wireless traffic on open hardware by the end of 2026. The foundation boasts a wide range of industry support beyond Ericsson, with other founding members including AMD, Verizon, Softbank Corp., and T-Mobile. This broad collaboration aims to ensure interoperability and a more competitive vendor ecosystem. A key objective of the OCUDU Ecosystem Foundation is to facilitate the dual use of commercial 5G technologies for specific defense applications, aligning with the requirements of the U.S. Department of War. The project seeks to help the department modernize its infrastructure with secure, open, and programmable network architectures. The push for Open RAN is closely tied to the development of AI-native 6G networks. NVIDIA, another founding member, is heavily promoting "AI-RAN" to embed artificial intelligence directly into the network architecture for real-time optimization of performance and energy use.
