Impact of 5G Connectivity on Industrial Automation and Smart Factories
Abstract
The rapid evolution of industrial automation and the emergence of smart factories have placed unprecedented demands on communication networks, requiring ultra-low latency, high reliability, and massive device connectivity. This paper investigates the role of 5G connectivity as a catalyst for the next generation of industrial automation, particularly within the context of Industry 5.0, where human-centric, resilient, and highly connected manufacturing systems are emphasized. By combining a comprehensive literature review, detailed case analyses of two smart factory pilots, and semi-structured interviews with industry experts and network engineers, the study examines the core enabling features of 5G, including ultra-reliable low-latency communications (URLLC), enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and network slicing. The findings demonstrate that 5G significantly enhances industrial operations by reducing latency from approximately 20 milliseconds (Wi-Fi) to around 1 millisecond, supporting high-bandwidth applications exceeding 200 Mbps, and providing reliable, deterministic communication across densely connected devices. These improvements facilitate real-time robotic control, collaborative human-machine interaction, augmented reality-assisted training, predictive maintenance, and high-resolution process monitoring. The study also identifies persistent challenges, including integration with legacy industrial control systems (ICS) and operational technology (OT), network slicing management, cybersecurity vulnerabilities, and regulatory compliance. Based on these insights, the paper provides a roadmap for 5G adoption in industrial settings, emphasizing best practices for deployment, integration, and operational optimization. Furthermore, it highlights key avenues for future research, including the development of secure and adaptive network management frameworks, advanced integration of edge computing, and strategies to ensure interoperability with existing industrial infrastructures. Overall, this study highlights the transformative potential of 5G in enabling highly responsive, flexible, and resilient smart factories, while providing a structured framework to guide industrial stakeholders in effectively leveraging 5G technologies.
