What is the difference between non-standalone and standalone 5G networks in automation?
Technically, according to 3GPP, the difference lies in control logic. Non-standalone (NSA) 5G networks rely on 4G/LTE infrastructure for control, whereas standalone (SA) 5G networks implement the full 5G core.
From a user perspective, SA-based private 5G networks (non-public networks, NPN) are simpler to deploy and require less integration effort.
From an application perspective, SA networks can support higher availability and reliability and reduce cycle times, particularly for NPN deployments.
Which industrial applications can benefit from 5G?
By definition, 5G encompasses technologies such as eMBB, uRLLC, eMTC, and RedCap, so it can support a wide range of applications.
For example, predictive maintenance, environment monitoring, service and configuration, connected tools, and connected safety personnel can benefit from functions defined for eMTC and RedCap. eMTC can operate alongside LTE-M and NB-IoT, and 3GPP continues to develop 5G use cases.
Additionally, industrial assembly solutions, process automation control, human-machine interfaces (HMI) with augmented reality assistance, as well as factory logistics, mobile robots, collaborative robots, and AGVs can benefit from RedCap and uRLLC features. Key requirements in these areas are deterministic response times, sufficient bandwidth, and cost-effective devices.
Over the coming years, verticals such as manufacturing (machinery, aerospace, automotive, semiconductors), chemicals and petrochemicals, pharmaceuticals, oil and gas, energy and utilities, and water and wastewater treatment are expected to adopt 5G. Adoption depends not only on technology but also on regulatory frameworks and availability of private spectrum.
How does 5G achieve instrument-level EVM performance in industrial automation?
First, consider features that differentiate 5G from previous generations. In applications requiring high reliability and availability, low latency is critical. Compared with previous generations, 5G is designed to significantly reduce latency and improve availability.
5G supports network slicing, enabling customized virtual networks tailored to specific application or service requirements. Industrial automation can therefore obtain dedicated slices optimized for its needs while ensuring high reliability and performance.
Edge computing will become increasingly important. 5G networks can leverage edge computing to process data closer to devices and sensors, reducing time and energy required to send data to remote data centers, thereby shortening response times and improving performance.
Finally, 5G supports mMTC, enabling massive numbers of devices to communicate simultaneously. For industrial automation, this allows many sensors, actuators, and devices on the same network to interoperate, improving overall efficiency from both utilization and investment perspectives.
How can 5G reduce machine downtime, eliminate errors, improve material traceability, and let staff focus on complex tasks?
5G itself does not directly change these parameters. The key is that it is implemented as part of an overall system. 5G enables secure communications within allocated spectrum, and wireless solutions can be more easily and flexibly integrated into industrial environments.
That integration enables more targeted collection and analysis of process data. This supports digital twins and reliable condition monitoring, allowing preventive actions to be taken.
When used effectively, organizations can execute processes reliably and establish flexible as-a-service models. This helps minimize downtime, prevent production errors, and enable targeted workforce allocation and material handling.
How does 5G accelerate digitization and enable energy savings?
5G is an important building block for digitization. Fundamentally, it helps achieve automation faster and drives organizations toward greater flexibility. Key elements include availability and reliability, which facilitate faster digital transformation and can contribute to energy-efficient operations through more precise, data-driven control.
What challenges and limitations arise when using 5G in industrial automation?
Technological development inevitably raises application-specific issues. 5G has strengths and weaknesses; time-critical applications requiring millisecond or even microsecond responses still require wired connections. At present, significant effort and cost have not been universally invested in building corresponding 5G solutions for all time-critical scenarios.
Even in the future, various technologies will coexist in industrial automation. There is no one-size-fits-all solution.
If organizations want to benefit from flexibility and private, secure campus coverage, they must build the necessary infrastructure, which requires initial investment. The first challenge is expectation management: more infrastructure-building options will emerge, and small-scale deployments will become feasible.
Where possible, the same infrastructure should support multiple use cases to maximize benefits. Network design must consider diverse requirements, and vendors must provide suitable equipment.
A key aspect is end-to-end traceability. Operators or integrators using 5G must be able to analyze each part of the communications infrastructure to quickly detect faults and restore operation.
Which 5G frequency bands are used for industrial automation, and what are their advantages?
From an application perspective: for predictive maintenance or environment monitoring, priorities include deeper coverage, many subscribers, and usable existing infrastructure. This typically uses traditional public network bands provided by mobile operators.
In scenarios such as process automation control or AR-assisted workflows, availability and reliability are critical. Private networks offer advantages for data security. Such facilities can use mid-band spectrum in the 3.xx to 4.xx GHz range; regulators have for years issued local licenses for these bands under relatively attractive terms.
Solution approaches for industrial 5G deployments
Because 5G combines multiple technologies addressing diverse market needs, meeting industrial automation requirements—low latency, moderate data rates, high reliability, and massive connections—requires a comprehensive product portfolio. Product attributes that support deployments include global single-SKU module options, stable feature sets with long-term roadmaps, and compliant supply chains to ensure availability and business continuity.
