Why Manufacturing Network Design Must Deliver Predictable Network Latency

There is a resurgence of manufacturing underway in the United States. The supply chain shocks of the pandemic and a renewed emphasis on domestic production driven by policy initiatives in Washington are reshaping the industrial landscape. Even before this shift, many manufacturers had been adopting industry 4.0 technology to improve productivity, resource efficiency and uptime.

Every day brings announcements of companies from around the world pledging billions of dollars in new plant investments. These projects are laying the foundation for a new type of manufacturing, one that is more connected, more automated, and more dependent on high-performing networks than ever before.

When a new factory is built today—or when an existing one is retooled—the underlying assumption must be that it will become a digitally integrated facility. Robots assemble products with precision timing, IoT sensors monitor every variable in the production line, AI systems scan for defects in real time, and connected platforms continuously optimize performance. These innovations are powerful, but they come with a non-negotiable requirement: the factory network design must deliver predictable low latency.

The Growing Demand for Connectivity

The number of connected devices in smart factories is rising at a staggering pace. In 2020, there were an estimated 81.7 million connected devices in manufacturing environments. By 2030, that figure is expected to surpass 200 million. Each of those devices - whether a robotic arm, a vision sensor, or a predictive maintenance system – depends on the network to transmit and receive data with precise timing.

Historically, wired Ethernet has been the gold standard on factory floors. It offers stability, reliability, low latency, and high throughput. However, cabling creates a network design rigidity that doesn’t align well with today’s flexible, hyper-connected factories. Rearranging production lines, adding new equipment, or scaling operations often requires extensive rewiring, which can increase costs and slow innovation.

For this reason, many manufacturing companies are exploring private 5G networks, which offer mobility, scalability, and freedom from physical cabling. Private 5G networks can be powerful, but they don’t inherently guarantee the ultra-low latency or deterministic latency required for real-time industrial applications. That’s where network design becomes critical.

In manufacturing environments, a network that offers high throughput, but inconsistent latency is unsuitable for many factory floor use cases. Predictable latency ensures that data flows through the system consistently and without jitter.

What Low Latency Really Means

Low latency enables the three pillars of smart manufacturing: real-time control systems, seamless machine-to-machine (M2M) communication, and remote monitoring. Each plays a critical role in creating a modern production environment.

• Real-Time Control Systems: Automated assembly lines, industrial robots, and process control systems require precise timing. If latency is too high or unpredictable, data transmission between sensors, actuators, and controllers is delayed. Even small delays can cascade into inaccurate movements, production errors, or malfunctions. In some cases, this can introduce safety hazards for workers or risk damage to expensive machinery. A predictable low-latency network design keeps real-time systems synchronized and reliable.

• Machine-to-Machine Communication: The Industrial Internet of Things (IIoT) depends on constant and deterministic communication between machines. A sensor detecting a temperature spike must instantly alert a cooling system. A robotic welder must coordinate with a positioning system so that every weld lands exactly where it should. These interactions only work efficiently if latency is minimal and predictable. Network designs that account for deterministic latency ensures that data can move between machines seamlessly, keeping production flowing smoothly.

• Remote Monitoring and Diagnostics: Factories no longer rely solely on on-site personnel to monitor systems. Increasingly, plants are leveraging remote experts who can analyze data, identify issues, and provide guidance in real time. For remote monitoring to be effective, the network must support low-latency communication. If delays are too long, diagnostics lose their value, and intervention may come too late. By designing networks with latency in mind, manufacturers can enable proactive maintenance and minimize costly downtime.

Looking Ahead: The Role of Private 5G and Beyond

As more manufacturers adopt private 5G, questions of network design become even more critical. Without the right architecture, private 5G networks may fail to deliver the latency performance needed for industrial use cases. The future of manufacturing networks will combine the mobility of private 5G with advanced synchronization and timing solutions that ensure deterministic performance.

In this environment, manufacturers must collaborate with network engineers who understand not only how to deliver bandwidth but also how to design for consistency and timing precision This requires deep knowledge of how industrial processes interact with network infrastructure and how every millisecond of delay can affect outcomes.

The SyncMetra Solution

Canoga Perkins developed the SyncMetra family of products to meet the unique performance required for manufacturing networks. SyncMetra solutions are designed to deliver predictable, ultra-low-latency wireless network performance, with precise synchronization that supports time-sensitive industrial applications.

For factories investing in private 5G or hybrid wired-wireless networks, SyncMetra provides assurance that latency will remain consistent—even under demanding operating conditions.

Conclusion

By building networks that prioritize predictable performance, manufacturers can embrace automation, robotics, and advanced analytics with confidence. The manufacturing renaissance underway in the U.S. and globally depends not just on physical infrastructure, but on digital infrastructure designed with precision. Network design done right will be the foundation that makes this new era of smart manufacturing possible.
