Manufacturers are expected to spend more than $1 billion on private 5G in 2025, according to ABI Research1according to ABI Research - and that figure is projected to grow at a 45.7% compound annual growth rate, surpassing $8.7 billion by 2030. For mid-sized U.S. plants, a critical driver of that acceleration is emerging federal and state funding tied directly to open-standards compliance. Grant eligibility is no longer purely a financial question - it is a technology architecture decision that shapes every layer of a facility's connectivity stack.
The Policy Foundation: Why Open Standards Are Now a Grant Condition
The shift begins with a legislative mandate. Over the next decade, NTIA will work to catalyze the development and adoption of open, interoperable, standards-based networks through the Public Wireless Supply Chain Innovation Fund - a ten-year grant program authorized under the FY2021 National Defense Authorization Act and funded through the CHIPS and Science Act of 2022.
The Public Wireless Supply Chain Innovation Fund will advance Open RAN through a $1.5 billion investment.2Commerce CHIPS Act Programs: - Status Report This is not a broadband build-out program - it is explicitly focused on breaking the proprietary stranglehold over wireless infrastructure. The 5G equipment market remains static: a small group of companies dominates it, some posing serious national security threats, while the lack of competition degrades supply chains, inflates prices, and blocks emerging players from entering.
The NTIA's 5G Challenge reinforces this orientation. In response to an industry dynamic that increases costs, slows innovation, and reduces competition, NTIA - in collaboration with the Department of Defense's Office of the Under Secretary of Defense for Research and Engineering - is carrying out the 5G Challenge to accelerate adoption of open interfaces, interoperable subsystems, and modular, multi-vendor solutions.
The Department of Defense has moved in parallel. The DoD's private 5G strategy leans on the Open Radio Access Network (O-RAN) concept, which emphasizes interoperable radio standards, hardware-agnostic networks, and the incorporation of cloud technologies. Officials have indicated they will encourage O-RAN ecosystem development by prioritizing those approaches in acquisition decisions.3Cyber Insights 2025: OT Security - SecurityWeek Defense-adjacent industrial suppliers and OEM manufacturers should note that this procurement posture establishes a compliance baseline now migrating into commercial manufacturing grant criteria.
What this means for applicants: Open RAN compliance - specifically adherence to O-RAN Alliance interface specifications - is a hard eligibility criterion for the programs most relevant to industrial private networks. Grant criteria explicitly cover promoting compatibility of new 5G equipment with future open standards-based interoperable equipment, managing integration of multi-vendor network environments, and identifying objective criteria to define equipment as compliant with open standards for multi-vendor network equipment interoperability.
The Retrofit Boom: Why Mid-Market Plants Are Moving Now
After years of pilots and proofs of concept, private 5G networks are operating inside real manufacturing environments across Europe, the U.S., and Asia. Automotive plants, semiconductor facilities, machinery workshops, and advanced logistics hubs are among the first to run production systems on private 5G rather than wired or Wi-Fi-only infrastructure.
The mid-market is following. Deployments are increasing across manufacturing, transportation and logistics, energy, healthcare, sports and stadiums, and mining. Manufacturing leads this sectoral adoption, driven by the density of automation assets that benefit immediately from low-latency wireless connectivity.
The retrofit use case - overlaying private 5G on existing plant infrastructure rather than constructing greenfield facilities - is particularly compelling for mid-sized operators. Private 5G enables wireless retrofits without tearing up floors to run cable or disrupting production. For plants managing tight capital budgets and continuous production schedules, this distinction is operationally significant.
In manufacturing, robotics, automated guided vehicles (AGVs), and predictive maintenance rank among the primary use cases powered by low-latency private networks. With reliable OT data in motion, manufacturers unlock predictive maintenance based on continuous acoustic, vibration, and thermal data to reduce unplanned downtime, as well as real-time quality control streaming high-definition vision data to edge compute for instant defect detection.
How Open Standards Shape Technology Stack Decisions
For automation integrators and equipment vendors, open-standards mandates are not merely a compliance checkbox - they restructure competitive positioning across the entire deployment stack.
Open RAN is interoperable. Network architects can curate components from different suppliers to build the best possible network, and new suppliers can enter the market with one component instead of an entire network architecture.4Funding Program Home | National Telecommunications and Information Administration This has direct implications for:
- Radio hardware: O-RAN-compliant radio units from multiple vendors can be combined, reducing dependency on legacy telecom incumbents
- Edge compute: Open interfaces enable hardware-agnostic edge platforms, allowing plants to select compute nodes that integrate with existing OT/ICS environments (OPC-UA, PROFINET, MQTT)
- Network management: Virtualized network functions (VNFs) can be updated independently, eliminating the need for full-stack vendor re-engagement
For system integrators, the shift creates both opportunity and complexity. Multi-vendor architectures demand deeper integration expertise - firms that can bridge 5G radio layer configuration, edge compute orchestration, and OT protocol translation are positioned to capture premium engagements.
Key Hurdles: What Is Slowing Grant-Aligned Deployments
Early deployments demonstrate both genuine advantages and practical challenges factories must confront when scaling from trials to live operations. Success depends as much on RF engineering, device readiness, and OT integration as on the 5G standard itself.
Three friction points consistently surface in mid-market deployments:
1. Vendor Lock-In Persistence
Despite open-standards mandates, many turnkey private 5G offerings bundle proprietary management platforms that re-create lock-in at the software layer. Plants should explicitly audit network management systems and OSS/BSS components - not just radio hardware - for O-RAN compliance.
2. OT/ICS Cybersecurity Integration
Private 5G networks introduce new threats but also grant operators full control over network infrastructure, delivering stronger security, data privacy outcomes, and flexibility when implemented correctly. However, a zero trust integration - supported by multiple visibility points and automated detection and response - is essential to protect critical applications, data, and systems.
According to IBM's X-Force 2026 Threat Intelligence Index, manufacturing has been the most targeted industry for five consecutive years, accounting for 27.7% of incidents across critical sectors. Introducing a new wireless air interface without corresponding OT segmentation and Zero Trust enforcement substantially expands the attack surface.
3. Workforce Training Gaps
Private 5G is increasingly deployed as an industrial LAN technology for factory robotics requiring low latency, including automated guided vehicles (AGVs), autonomous mobile robots (AMRs), and other IIoT devices. However, the skills required to operate these networks - RF engineering, 5G core management, edge AI operations, and OT cybersecurity - rarely exist within plant maintenance teams. Grant applications that include structured workforce development plans score more favorably with state-level reviewers.
A Six-Step Implementation Roadmap for Plants Planning 5G Deployments
The following sequence reflects both technical best practice and grant application alignment:
Step 1 - OT/IT Connectivity Audit Map all existing wired and wireless connections on the plant floor, including legacy SCADA, PLC, and ICS segments. Identify coverage gaps and latency-sensitive processes before specifying 5G infrastructure.
Step 2 - Verify O-RAN Compliance Require vendors to demonstrate compliance with O-RAN Alliance specifications and confirm multi-vendor interoperability. Grant eligibility under NTIA programs depends on meeting these criteria - non-compliant gear disqualifies applications.
Step 3 - Segment the OT/IT Network First Apply network micro-segmentation to ICS zones before introducing the 5G air interface. CISA's Cyber Performance Goals (CPGs 2025) focus on enhancing OT network segmentation, enforcing Zero Trust principles, and strengthening supply chain security.
Step 4 - Engage a Qualified System Integrator Early Select integrators with documented experience bridging private 5G infrastructure, edge compute platforms, and OT/ICS protocols. Grant applications often require project partners with relevant credentials.
Step 5 - File for Federal and State Funding in Parallel Align the project timeline with NTIA Notice of Funding Opportunity windows and applicable state manufacturing innovation grants. Consistent open-standards documentation is required across submissions.
Step 6 - Include a Workforce Training Plan in the CapEx Proposal Training costs for 5G network management, edge AI, and OT cybersecurity should be built into budget submissions. Several state programs explicitly reward workforce upskilling commitments.
Implications for Automation Providers and System Integrators
The open-standards grant environment creates a structural market shift for the automation supply chain. This critical investment will help drive U.S. wireless innovation, foster competition, and strengthen supply chain resilience - and help unlock opportunities for U.S. companies, particularly small and medium enterprises, to compete in a market historically dominated by a few foreign suppliers.
For automation integrators, this translates to:
- Certification advantage: O-RAN interoperability certifications become a procurement differentiator, not just a technical specification
- Portfolio expansion: Edge AI platform capabilities that operate across multi-vendor 5G infrastructure become a margin-generating service line
- Grant facilitation services: Integrators who can guide plants through NTIA application requirements - including open-standards documentation and cybersecurity compliance attestations - add measurable value beyond traditional integration work
The mid-market private 5G retrofit wave is not a distant trend. Funding mechanisms are in place, deployment methodologies are maturing, and open-standards requirements are narrowing the viable technology choices. Automation providers who align their portfolios accordingly will be positioned at the center of one of manufacturing's most consequential infrastructure transitions.

Frequently Asked Questions
What does "open standards" mean in the context of private 5G grant eligibility? Grant programs such as the NTIA Public Wireless Supply Chain Innovation Fund require O-RAN (Open Radio Access Network) architecture - a framework specifying open, interoperable interfaces between radio units, distributed units, and centralized units. Equipment must comply with O-RAN Alliance specifications, enabling multi-vendor deployments rather than single-supplier lock-in.
Can a mid-sized plant retrofit an existing Wi-Fi or wired OT network with private 5G? Yes - one of the primary advantages of private 5G is wireless retrofit capability without major cabling disruption. However, a thorough RF site survey and OT network segmentation exercise are prerequisites to ensure the 5G overlay does not introduce new attack surfaces into legacy ICS environments.
How does vendor lock-in manifest in private 5G deployments, and how does O-RAN address it? Traditional private 5G deployments bundle radio hardware, core software, and management platforms from a single vendor. O-RAN separates these layers through standardized interfaces, allowing plants to swap radio units, upgrade core software, or add edge compute nodes from different vendors - reducing long-term dependency and total cost of ownership.
Which automation providers and system integrators are best positioned for this market? Integrators with competency in both telecom-layer integration (O-RAN, 5G core configuration) and OT protocol expertise (OPC-UA, PROFINET, MQTT) are best positioned. Vendors offering hardware-agnostic edge compute platforms that orchestrate workloads across multi-vendor 5G infrastructure hold a clear advantage as open-standards mandates take hold.
