Siemens' Private 5G Strategy: Practical Automation Over Technology Theater

From Technology Hype to Practical Automation: Siemens' Private 5G Pivot

The industrial automation landscape is witnessing a significant shift in how advanced connectivity technologies are being deployed. Siemens, the German industrial giant, has found its groove with private 5G by adopting a fundamentally different approach—positioning it as an enabling technology embedded within comprehensive automation solutions rather than as a standalone product. This strategic pivot reflects a broader industry trend where enterprises are rejecting flashy technology theater in favor of practical solutions that solve specific business problems.

The Reality Check: Industry 4.0's Measured 5G Adoption

According to Siemens' latest market observations, Industry 4.0 interest in private 5G is indeed growing, but the adoption curve is proving to be slower and more use-case driven than vendors initially anticipated. The "silver-bullet" pitch that characterized early 5G marketing has proven to be a tough sell in industrial environments where reliability, security, and return on investment matter more than technological novelty.

"Enterprises don't want to talk about technology for technology's sake," explains Siemens' approach. "They don't generally buy the big tech vision. What they want are solutions that solve specific business problems." This customer-centric philosophy has guided Siemens' successful repositioning of private 5G as an embedded enabler rather than a standalone product.

The Siemens SCALANCE Ecosystem: Industrial 5G Made Practical

Siemens' practical approach is embodied in its SCALANCE Industrial 5G ecosystem, which includes:

• SCALANCE MUB852-1 5G router – Designed for industrial applications with robust performance requirements
• Complete private 5G infrastructure – Including 5G core, Radio Access Network (RAN), and Radio Units
• PROFINET communication integration – Ensuring seamless compatibility with existing industrial networks
• End-to-end security solutions – Critical for industrial environments with sensitive operations

This comprehensive ecosystem enables industrial companies to build their own local 5G networks that provide optimal support for automation applications, maintaining full control over network operations while integrating Industry 4.0 applications.

Where Private 5G Delivers Real Value

Siemens identifies specific industrial scenarios where private 5G delivers tangible benefits:

• Flexible manufacturing lines – Supporting wireless control of AGVs (Automated Guided Vehicles) and real-time monitoring
• Mobile robotics coordination – Enabling real-time communication for autonomous mobile robots
• Pharmaceutical cleanrooms – Wireless connectivity for mobile devices and sensors in GMP environments
• Warehouse automation – Real-time coordination of AMRs (Autonomous Mobile Robots) and AGVs
• Remote maintenance and monitoring – High-bandwidth video analytics and AR/VR applications

"Industries that have real connectivity problems and expensive critical assets are looking at this," says Siemens, highlighting the practical rather than theoretical applications driving adoption.

Market Context: The Growing Industrial Wireless Automation Landscape

The global industrial wireless automation market, valued at $16.5 billion in 2024, is forecasted to grow at a CAGR of 8%, reaching significant scale by 2033. Meanwhile, the factory automation PLC market itself was valued at $9.37 billion in 2024 and is projected to reach $10.12 billion in 2025.

Key market drivers include:

• Wireless IoT device growth – Forecasted to increase from 56.5 million units in 2023 to 110.3 million by 2028
• Industry 4.0 adoption acceleration – Manufacturers increasingly investing in connected automation solutions
• Flexibility demands – Need for reconfigurable production lines and mobile automation
• Skilled labor shortages – Driving automation adoption across manufacturing sectors

The PLC Evolution: From Wired to Wireless Integration

Modern PLC systems are evolving beyond traditional wired architectures to embrace wireless connectivity. Siemens' approach demonstrates how next-generation PLCs must integrate seamlessly with wireless technologies like private 5G to enable:

• Distributed control systems – With wireless I/O modules and field devices
• Mobile HMI interfaces – Real-time monitoring and control from anywhere in the facility
• Edge computing integration – Processing data closer to where it's generated
• Cloud connectivity – For analytics, predictive maintenance, and remote management

Expert Insight: Why the Practical Approach Wins

Industry analysts note that Siemens' success with private 5G reflects a broader market reality: industrial customers are increasingly sophisticated about technology investments. They're looking for solutions that:

• Solve specific pain points – Rather than offering generalized technology benefits
• Integrate with existing infrastructure – Minimizing disruption and maximizing ROI
• Provide measurable business outcomes – Such as increased uptime, reduced maintenance costs, or improved flexibility
• Offer clear security and reliability guarantees – Critical for industrial operations

This approach contrasts sharply with earlier technology rollouts that emphasized features over practical benefits.

The Future: Embedded Connectivity as Standard

Looking ahead, Siemens' strategy points toward a future where advanced connectivity technologies like private 5G become standard embedded features in industrial automation solutions rather than separate technology purchases. This evolution will likely accelerate as:

• Costs continue to decrease – Making wireless connectivity more accessible
• Standards mature – Ensuring interoperability across different systems
• Use cases proliferate – Demonstrating clear ROI in diverse industrial settings
• Integration deepens – With PLCs, SCADA systems, and industrial software platforms

Conclusion: Practical Automation for Real-World Challenges

Siemens' successful pivot with private 5G offers valuable lessons for the entire industrial automation sector. By focusing on practical applications rather than technological theater, and by embedding advanced connectivity within comprehensive automation solutions, companies can deliver real value to industrial customers.

The market is clearly moving toward integrated, wireless-enabled automation systems that prioritize reliability, security, and business outcomes over technological novelty. As the global factory automation PLC market continues its steady growth—projected to reach $15.89 billion by 2031—this practical approach will likely become the industry standard.

For industrial enterprises evaluating their automation strategies, the message is clear: look beyond the technology hype to solutions that solve your specific business challenges. Whether it's increasing production flexibility, reducing maintenance costs, or enabling new operational capabilities, the right automation solutions should deliver measurable results, not just technological features.
