The U.S. Department of Commerce’s National Telecommunications and Information Administration (NTIA) has announced a $450 million funding opportunity to drive innovation in Open RAN software solutions. The funding, part of the $1.5 billion Wireless Innovation Fund established under the CHIPS and Science Act of 2022, seeks to promote open, interoperable wireless networks and strengthen supply chain resilience.
This third Notice of Funding Opportunity (NOFO) targets software development that unlocks new revenue streams for industries like utilities, manufacturing, and mining, while reducing the cost and complexity of multi-vendor integration through automation. Applications for the funding are due by March 17, 2025, with the goal of advancing secure, cost-efficient, and scalable Open RAN technologies.
“Wireless innovation is critical for maintaining America’s technology leadership,” said Commerce Secretary Gina Raimondo. NTIA Administrator Alan Davidson emphasized the fund’s focus on enhancing security, fostering competition, and leveraging U.S. software expertise to modernize wireless networks. To date, NTIA has awarded over $413 million in prior rounds to support testing and commercialization of Open RAN solutions.
• Funding Amount: $450 million for Open RAN software innovation.
• Focus Areas:
• Developing software for industry-specific applications using Open RAN.
• Automating multi-vendor network integration to reduce costs and complexity.
• Application Deadline: March 17, 2025.
• Program Background: Part of the $1.5 billion Wireless Innovation Fund under the CHIPS and Science Act.
• Previous Funding:
• $413 million awarded to 24 grantees for testing and development.
• $273 million recently announced for Open RAN commercialization projects.
“NTIA’s Wireless Innovation Fund will help improve the security of wireless equipment, unlock new revenue streams, and reduce integration costs,” said Alan Davidson, Assistant Secretary of Commerce for Communications and Information.
- Open RAN (Open Radio Access Network) is an industry movement aimed at disaggregating the traditional, proprietary components of mobile network infrastructure to create a more open, interoperable ecosystem. In a conventional RAN, the hardware and software are tightly integrated by a single vendor, which limits flexibility and vendor diversity. Open RAN, by contrast, separates hardware and software functions and introduces open interfaces, enabling different vendors to supply components that can work together in a single network. This approach fosters competition, innovation, and potentially reduces network deployment costs for mobile operators. Open RAN also enables the deployment of cloud-native architectures and software-defined networking (SDN) principles, making networks more flexible and easier to scale.
- Standardization plays a critical role in the development and success of Open RAN. The O-RAN Alliance, a leading industry body, defines technical specifications and open interfaces that ensure interoperability between vendors. It has developed key standards such as the O-RAN architecture with components like the Near-RT RIC (Near Real-Time RAN Intelligent Controller) and Open Fronthaul Interface. The Telecom Infra Project (TIP) also plays a significant role in promoting Open RAN through collaborative efforts on network trials and implementation frameworks. Meanwhile, 3GPP continues to standardize the underlying 5G technologies that Open RAN solutions build upon, ensuring alignment with global cellular standards. These efforts collectively aim to create a vendor-agnostic, flexible network environment that benefits both mobile operators and end users.
- In 2024, the Open RAN ecosystem witnessed significant advancements and collaborations aimed at enhancing network performance, interoperability, and global adoption. The O-RAN ALLIANCE conducted its Global PlugFest Spring 2024 from February to May, engaging 86 companies across 18 labs worldwide. This event focused on themes such as energy efficiency, consistent open fronthaul testing, and system testing with Layer 1 acceleration, contributing to the maturation of Open RAN technologies. Additionally, the O-RAN ALLIANCE initiated its second Global PlugFest of 2024 in the fall, emphasizing energy efficiency testing and open fronthaul advancements, with results anticipated by late November.
- Strategic partnerships further propelled Open RAN’s progress. In August, the Alliance for Telecommunications Industry Solutions (ATIS) and the O-RAN ALLIANCE signed a Memorandum of Understanding to transpose O-RAN specifications into ATIS standards, aiming to accelerate Open RAN adoption in North America.
- In December, Liberty collaborated with Samsung to deploy 5G Open RAN in Puerto Rico, marking the region’s first rollout of such technology and enhancing network flexibility and resilience.
- Moreover, the National Telecommunications and Information Administration (NTIA) awarded $42 million to the Acceleration of Compatibility and Commercialization for Open RAN Deployments (ACCoRD) project, establishing a testing and R&D center in the Dallas Technology Corridor to further Open RAN development. These initiatives underscore the industry’s commitment to advancing Open RAN technologies and fostering a diverse, interoperable network ecosystem.
