Private 5G enables industrial automation for smart manufacturing and digital transformation

Industrial automation stands at the threshold of a revolutionary transformation as private 5G networks emerge as a cornerstone technology for smart manufacturing and digital transformation initiatives across the UK and Europe. 

The private 5G network market demonstrates explosive growth potential, expanding from £1.6 billion currently to a projected £28.7 billion by 2030, achieving an impressive compound annual growth rate of 51%.

This remarkable expansion reflects the technology's ability to address specific smart manufacturing requirements through dedicated network frequencies and enhanced operational capabilities. Private 5G enables manufacturers to overcome traditional wireless limitations while supporting comprehensive digital transformation strategies within industrial facilities.

Technical architecture and core benefits of private 5G networks

Private 5G networks leverage dedicated spectrum frequencies to deliver superior performance compared to traditional cellular networks sharing public airwaves. These specialised frequencies, including bands such as n77 and n79 used across Europe and Asia, prevent wireless interference from competing signals.

The architecture delivers exceptional bandwidth capacity, ultra-low latency communication, and extensive Industrial IoT capabilities essential for modern manufacturing operations.

Local data storage represents a fundamental advantage, allowing sensitive manufacturing data to remain within facility boundaries rather than travelling across public networks. This approach enhances security protocols while maintaining complete control over information flow. The technology supports Layer 2 tunnelling capabilities, enabling seamless end-to-end communication between terminal devices and central control systems.

Unlike traditional Layer 3 architectures, this tunnelling approach preserves native industrial protocols while leveraging advanced 5G infrastructure for reliable transmission across factory environments.

Current manufacturing applications and use cases

Smart manufacturing facilities increasingly deploy private 5G networks to support critical automation equipment, including programmable logic controllers (PLC), automated guided vehicles (AGV), automated mobile robots (AMR), and rail-guided vehicles (RGV). 

These applications demonstrate the technology's versatility in supporting both standard operational systems and safety-critical control systems requiring guaranteed response times.

The integration with EtherNet/IP communications enables seamless connectivity between existing industrial equipment and modern 5G infrastructure. Real-world trials across Europe and Asia have validated the technology’s readiness for large-scale deployment, confirming its ability to enhance both productivity and operational safety.

Manufacturing operations benefit from enhanced mobility support, allowing robots and automated systems to maintain connectivity while moving throughout expansive factory floors, often exceeding 5,000 square metres. These applications showcase private 5G’s ability to support diverse industrial automation requirements while maintaining the reliability standards demanded by modern manufacturing processes.

Implementation challenges and system integration

Deploying private 5G networks in manufacturing environments requires careful reconciliation between information technology priorities, emphasising security, and operational technology requirements, focusing on availability. 

This fundamental conflict creates implementation complexity that system integrators must navigate with precision and advanced planning. Infrastructure deployment demands comprehensive planning for 5G gateways, base stations, core networks, and Multi-access Edge Computing components.

Device management presents ongoing challenges encompassing authentication protocols, firmware updates, continuous status monitoring, and historical message analysis. Integrating with existing industrial systems also requires enabling 5G communication for Layer 2 packet transmission, as most industrial equipment still operates primarily at this level.

These technical challenges require specialised expertise and collaboration between IT and OT teams to ensure successful deployment across diverse manufacturing environments.

Hardware solutions and performance enhancement

Modern private 5G gateways feature remarkably compact designs measuring just 100 x 125 x 35 mm (approximately 0.0125 square metres)while consuming minimal power, averaging 8 watts, significantly improving battery life and reducing maintenance costs. These specifications enable deployment in space-constrained industrial environments without compromising performance. 

Dual-SIM redundancy ensures industrial-grade reliability, providing automatic switching capabilities to maintain uninterrupted connectivity during network transitions.

Signal enhancement accessories play crucial roles in optimising network performance, with low-noise amplifiers strengthening reception quality and specialised boosters supporting TDD Duplex mode operations. These solutions can improve signal strength and transmission range by up to 50%, addressing coverage limitations in large facilities often exceeding 10,000 square metres.

Wide temperature operation models accommodate harsh industrial environments where standard equipment might fail, ensuring consistent network reliability across diverse operational conditions.

Network management and device lifecycle solutions

Centralised network management capabilities leverage Device Lifecycle Management software supporting Open Mobile Alliance LwM2M protocol standards for comprehensive administrative control. This framework provides IT administrators with unified network visibility and faster fault detection across multiple manufacturing sites.

• Secure software updates maintain system integrity while enabling continuous improvement of connected devices.
  
• Real-time monitoring tracks network performance metrics and device status.
  
• Detailed log access offers in-depth troubleshooting information for maintenance teams.
  
• Remote management tools allow efficient administration without frequent on-site visits.
  
• Automated alerts notify operators of potential issues before they affect production output.

These management solutions streamline operations while reducing the complexity of maintaining extensive industrial IoT deployments across multiple facility locations.

Private 5G advantages over traditional wireless technologies

Traditional Wi-Fi operates as "best effort" communication with performance heavily dependent on traffic load, environmental factors, and competing devices sharing the same spectrum. This results in unpredictable connectivity that industrial production lines cannot depend upon.

Wi-Fi also utilises unmanaged Industrial, Scientific, and Medical (ISM) spectrum shared by numerous wireless technologies, creating significant interference potential in industrial environments.

Private 5G access points offer coverage areas three to five times larger than typical Wi-Fi installations, while providing superior performance in areas with physical obstacles such as steel frameworks or concrete barriers.

The licensed spectrum bands used for private 5G in the UK and Europe include strong interference management protocols, ensuring stable and consistent signal quality.

Industrial environments with metal structures and thick walls present unique challenges for wireless signals, but private 5G networks consistently demonstrate superior penetration and reliability compared to traditional Wi-Fi or other wireless solutions — ensuring uninterrupted connectivity throughout complex manufacturing facilities.
