A convergence of federal grant funding and open-standards private 5G architecture is accelerating network modernization at mid-sized U.S. manufacturing plants, creating new demand for system integrators and raising operational technology (OT) training requirements. The catalyst is the National Telecommunications and Information Administration's (NTIA) Public Wireless Supply Chain Innovation Fund, whose third funding round explicitly targets manufacturing as a priority vertical. Industry analysts say the resulting wave of industrial connectivity retrofits has moved well beyond the pilot stage.
Background
Funded by the CHIPS and Science Act of 2022, the $1.5 billion Public Wireless Supply Chain Innovation Fund invests in American technology leadership in mobile telecommunications networks, aiming to drive wireless innovation, foster competition, and strengthen supply chain resilience. The program has proceeded through sequential Notices of Funding Opportunity (NOFOs): the first round addressed research, development, and testing of Open Radio Access Network (Open RAN) components, while the second supported commercialization of open radio units. NTIA has awarded over $550 million across 35 projects through the first two funding rounds.
Open RAN is the technical architecture at the center of this push. Unlike proprietary, closed-network designs, Open RAN enables competition and innovation by allowing operators to mix and match software and hardware components from different companies. For industrial facilities, this translates directly into reduced vendor lock-in during retrofit projects - a significant consideration for plants operating multi-decade equipment lifecycles alongside modern robotics and sensors.
Details
The third NOFO, for which more than 90 applications requesting nearly $3 billion were submitted, names manufacturing as a priority. The round will invest in software solutions that utilize Open RAN interfaces and leverage Open RAN-specific innovations, such as the RAN Intelligent Controller (RIC), to drive energy efficiencies, cost savings, or productivity gains for industry verticals including manufacturing. A second funding track targets multi-vendor integration complexity - a persistent pain point for automation vendors and integrators deploying heterogeneous sensor and robotics environments. NTIA plans to issue grants ranging from $24 million to $50 million for industry vertical solutions and from $9 million to $18 million for integration automation solutions.
Private 5G offers tangible retrofit advantages in plant environments. According to Ericsson, wireless retrofits can be completed without tearing up floors to run cable or disrupting production - a critical attribute for mid-sized facilities that cannot absorb extended downtime. The 5G private network market was estimated at $3.06 billion in 2025 and is expected to reach $18.68 billion by 2030, at a compound annual growth rate of 43.60%. Declining hardware costs are a parallel driver: sub-$150 industrial routers now allow mid-sized factories to retrofit robotics without removing existing Ethernet infrastructure.
The interoperability challenge, however, remains a structural obstacle for system integrators. Industry leaders formed the 5G Operational Technology Alliance (5G-OT Alliance) in May 2025, citing deployment complexity as a primary barrier to adoption. Founding members include John Deere, BASF, and Hamburger Containerboard. The alliance focuses on security, interoperability, education, and use-case development across industrial sectors. Separately, the Department of Commerce's Office of Inspector General flagged in a 2025 report that the Innovation Fund operates in a fast-changing area that "could increase the risk of mismanagement of government funds," recommending a more comprehensive control framework.
For automation vendors, the NTIA funding structure carries direct commercial implications. The Innovation Fund's third round targets software solutions that reduce the cost and complexity of multi-vendor integration through automation - effectively subsidizing development of the middleware and orchestration layers integrators depend on to bridge legacy programmable logic controllers (PLCs) with 5G-connected edge compute nodes. Bridging IT and OT environments at scale demands personnel with overlapping competency in both domains, a skills gap that training programs tied to grant deliverables are beginning to address.
Outlook
Award decisions for the third NOFO are pending following the April 2025 application deadline, and NTIA has indicated at least one additional funding round is planned. The volume of submissions - nearly $3 billion in requests against a $450 million available pool - signals that demand from industry consortia and technology developers substantially exceeds current appropriations. For plant operators evaluating capital expenditure timelines, grant award announcements will serve as a key indicator of when co-funded retrofit programs may become accessible, particularly for facilities in the 100-500 employee range that lack the in-house engineering capacity to self-fund Open RAN integration projects.
