Meanwhile, the U.S. Department of Defense's adoption of private 5G at its Georgia logistics base underscores the technology's strategic value, achieving a 65% increase in goods velocity and 98% inventory reordering accuracy Private 5G installations and impacts – 20+ of the best^[3].

Vertical Adoption: Mining and Public Safety as Early Winners

Mining and public safety have emerged as two of the most transformative verticals for private 5G. In mining, Newmont's deployment of a production-grade private 5G network at its Cadia mine in Australia enabled remote-controlled operation of dozers across a 2.5 km tailings area, resolving Wi-Fi connectivity issues that previously caused significant downtime Private 5G installations and impacts – 20+ of the best^[3]. The network's ability to support real-time data transmission and autonomous systems is redefining safety and efficiency in hazardous environments.

Public safety applications are equally groundbreaking. The city of Istres in France reduced video surveillance camera installation costs by eliminating fiber-based infrastructure through a private 5G network Private 5G installations and impacts – 20+ of the best^[3]. Meanwhile, the U.S. Marine Corps' logistics base achieved a 55% reduction in labor costs by automating warehouse management with 5G-enabled systems Private 5G installations and impacts – 20+ of the best^[3]. These use cases highlight private 5G's capacity to deliver mission-critical connectivity where traditional networks fall short.

Infrastructure Submarkets: RAN, 5GC, and Transport Systems as Strategic Investment Opportunities

The scalability and performance of private 5G networks hinge on three core infrastructure components: the Radio Access Network (RAN), 5G Core (5GC), and transport systems. Each represents a high-growth submarket with distinct investment potential.

1. Radio Access Network (RAN): The RAN is the backbone of private 5G, enabling seamless connectivity for industrial IoT devices, autonomous robots, and real-time monitoring systems. The global 5G RAN professional services market is projected to grow at a 17% CAGR from 2025 to 2030, driven by demand for AI-driven network automation and edge computing solutions 5G RAN Professional Services Market | Industry Report, 2030^[6]. Startups like Celona and Anterix are pioneering secure, scalable RAN deployments tailored for enterprise needs 4 Common Use Cases for Private 5G as a Service^[5].

2. 5G Core (5GC): The 5GC is critical for standalone 5G implementations, offering guaranteed quality-of-service (QoS) control and advanced features like network slicing. Its ability to support mission-critical applications—such as URLLC for autonomous vehicles and mMTC for smart grids—makes it indispensable for industrial adoption Private 5G Market^[4].

3. Transport Systems: Advanced transport systems ensure low-latency data transfer across private 5G networks, a necessity for applications like distributed PLC environments and AR-assisted troubleshooting. The integration of fiber-optic and wireless backhaul solutions is expected to drive cost savings and operational efficiency, particularly in energy and transportation sectors Private 5G installations and impacts – 20+ of the best^[3].

The Road Ahead: Challenges and Opportunities

Despite its promise, the private 5G market faces hurdles, including high infrastructure costs and slow ROI for operators 5G RAN Professional Services Market | Industry Report, 2030^[6]. However, the convergence of AI, cloud-native solutions, and government incentives is mitigating these risks. For example, AI-driven network automation is optimizing performance and reducing operational overhead, while startups like Athonet are introducing secure, scalable solutions for enterprise-grade networks 4 Common Use Cases for Private 5G as a Service^[5].

Investors should focus on companies positioned at the intersection of RAN innovation, 5GC deployment, and transport system integration. With the market set to outpace even the most optimistic forecasts, private 5G infrastructure is not just a technological leap—it's a $5 billion opportunity waiting to be unlocked.
