5G NON-PUBLIC NETWORKS FOR INDUSTRY 4.0: ARCHITECTURE, USE CASES, AND FUTURE DIRECTIONS

Abstract

The integration of 5G Non-Public Networks (NPNs) in Industry 4.0 has the potential to revolutionize industrial automation by offering ultra-reliable, low-latency communication, and secure connectivity for mission-critical applications. This paper explores the role of 5G NPNs in industrial environments, highlighting the architectural components, deployment models, and key use cases, such as real-time control, predictive maintenance, and remote monitoring. The paper also addresses the challenges associated with NPN deployment, including spectrum management, latency issues, and integration with legacy systems. We provide recommendations for industrial adopters, emphasizing the need for hybrid deployments, careful spectrum planning, and the adoption of edge computing to minimize latency. Additionally, the paper outlines the future research directions, including the role of AI/ML in optimizing 5G NPNs and the importance of security and energy efficiency in the sustainable deployment of 5G networks.
