Ericsson Backs Open RAN Foundation
Ericsson has joined the OCUDU Ecosystem Foundation as a founding member under the Linux Foundation. The move is aimed at advancing open-source and interoperable radio access network (RAN) technology in the U.S. Ericsson will provide architectural guidance to support the development of open and flexible wireless networks.
Open RAN, or Open Radio Access Network, represents a move away from the traditional "single-vendor" approach to building mobile networks. Historically, a mobile operator would buy all the components for a cell tower—the radios, hardware, and software—from a single company. Open RAN technology unbundles these components, creating standardized, open interfaces that allow operators to "mix and match" solutions from various vendors. This shift is designed to increase competition and innovation in the telecom supply chain. By avoiding vendor lock-in, network operators can potentially lower costs and have more flexibility to choose the best-in-class technology for each part of their network. The O-RAN Alliance, a global community of mobile operators and vendors, is the primary group defining the specifications for these open interfaces. Ericsson's deeper involvement in open-source initiatives follows a landmark $14 billion deal with AT&T. This agreement will see Ericsson lead the carrier's push to have 70% of its wireless network traffic flowing across open-capable platforms by late 2026. As part of the deal, AT&T and Ericsson have already completed successful Open RAN calls using third-party radios from Fujitsu, demonstrating the interoperability of the technology. The U.S. government has a significant interest in promoting Open RAN. The National Telecommunications and Information Administration (NTIA) is administering a $1.5 billion Public Wireless Supply Chain Innovation Fund to support the development and deployment of open and interoperable networks. This is seen as a strategic move to bolster the American telecommunications equipment industry and provide a competitive alternative to Chinese manufacturers like Huawei and ZTE. The OCUDU Ecosystem Foundation is a public-private partnership that received initial funding from the U.S. Department of Defense's FutureG Office. Premier members of the foundation include not only Ericsson but also its chief rival Nokia, alongside tech giants like NVIDIA and major carriers AT&T and Verizon. This new foundation aims to create an open-source software stack for the core components of the radio access network, specifically the Centralized Unit (CU) and Distributed Unit (DU). The goal is to establish a common, AI-native software base that can accelerate innovation for both 5G and the early development of 6G networks.
