Manufacturing has long been one of the most compelling environments for private cellular networks. Factories increasingly rely on automation, real time analytics, robotics and connected systems that demand reliable, low latency connectivity. Among the companies actively deploying these technologies in their own operations is LG Electronics, which has been using 5G private networks as a foundation for its smart factory strategy.
In recent years the company has also begun positioning itself as a provider of 5G private network solutions, using its internal manufacturing facilities as reference deployments. This approach reflects a broader trend in industry where technology developed for internal digital transformation becomes a commercial offering for other enterprises.
A platform for smart manufacturing
Private 5G networks are designed to provide dedicated connectivity within a specific location such as a factory, logistics centre or campus. Compared with public mobile networks, they allow organisations to maintain full control over performance, security and data flows.
For smart factories this can be particularly valuable. Production environments involve hundreds or thousands of connected devices including robots, sensors, cameras and autonomous vehicles. These systems generate large volumes of data and often require extremely reliable communication between machines and control systems.
LG has developed a software centric private 5G solution that handles functions normally associated with traditional network infrastructure, including the radio access network and the 5G core. By virtualising these elements in software, the system can be upgraded or expanded without replacing hardware. This reduces operational costs and allows factories to evolve their connectivity infrastructure as production needs change.
The architecture also supports flexible deployment models. Some customers may require fully isolated networks for sensitive operations, while others may need integration with external cloud services for collaboration with partners and suppliers.
Beyond connectivity itself, the platform includes a device management layer capable of integrating a wide range of equipment. This includes LG’s own robotics and automation systems, along with third party devices such as CCTV cameras, safety systems and industrial sensors.
Real world testing in LG factories
LG has been testing and refining its private 5G technology across several operational sites, including manufacturing plants, logistics centres and healthcare facilities. One of the most notable examples is the company’s highly automated appliance factory in Clarksville, Tennessee.
The facility assembles washing machines and dryers for the North American market and represents one of LG’s most advanced manufacturing sites. More than 900 employees work alongside a large fleet of robots and mobile machines. Around 200 automated guided vehicles and autonomous mobile robots move parts and components across the factory floor, while more than 130 industrial robots perform tasks such as welding, fastening, painting and inspection.
Connectivity plays a critical role in enabling these systems to operate efficiently. Mobile robots transport heavy components between production areas and must maintain continuous communication with factory control systems to coordinate their movements. Some of these machines are equipped with 5G connectivity developed through collaboration with LG Uplus, the telecommunications arm of the broader LG group.
The Clarksville plant currently operates with both Wi Fi and private 5G connectivity. Over time the goal is to transition more production equipment to 5G to enable more robust communication between machines, systems and workstations.
Automation, data and digital twins
Connectivity is only one part of the smart factory equation. LG’s manufacturing strategy also incorporates artificial intelligence, advanced analytics and digital twin technologies to optimise production processes.
The Clarksville plant produces a new appliance roughly every few seconds across its production lines. Maintaining quality and efficiency at this scale requires constant monitoring of equipment performance, inventory levels and production status.
Digital twin systems replicate the factory environment in real time, enabling engineers to visualise operations and identify potential issues before they affect production. These virtual models allow managers to simulate adjustments to production lines and evaluate the impact before implementing changes on the shop floor.
Artificial intelligence systems analyse production data and detect patterns that may indicate potential faults or performance problems. Predictive maintenance platforms monitor equipment conditions such as vibration and motor speed, helping engineers schedule repairs before machines fail.
Machine vision systems also play a major role in quality control. Cameras capture images of products during assembly and compare them with reference models to detect defects or anomalies. These systems can identify issues ranging from incorrect component placement to cosmetic imperfections.
Together, these technologies have helped the factory achieve measurable improvements in productivity, energy efficiency and product quality.
From internal capability to commercial offering
LG’s experience in its own manufacturing facilities has provided a testing ground for its industrial connectivity and automation technologies. The company has accumulated tens of thousands of telecommunications patents, including many related to 5G technologies, and has expanded its activities into telecommunications infrastructure.
In South Korea, its private 5G solution recently received certification from the Korea Association of Network Industries, confirming that the technology is domestically developed and manufactured. This recognition supports its ability to supply networking solutions to public sector organisations as well as private enterprises.
At the same time, LG has started promoting its smart factory capabilities as a service offering for other manufacturers. These initiatives include support for factory design, process optimisation, digital transformation and the integration of advanced automation technologies.
The strategy reflects the growing demand for industrial connectivity platforms that combine networking, data analytics and automation into a unified system.
Private networks and the future of manufacturing
The use of private cellular networks in manufacturing continues to expand as factories become more digital and autonomous. Advanced production environments rely on continuous communication between machines, robots and software platforms. Traditional wireless systems can struggle to provide the reliability, coverage and performance required in these conditions.
Private 5G networks offer a way to deliver predictable connectivity tailored to the specific needs of each facility. When combined with AI driven analytics, robotics and digital twins, they form the foundation for highly automated production systems.
LG’s smart factories illustrate how these technologies can come together in a real world environment. By deploying private 5G networks alongside advanced automation and data platforms, manufacturers can create production systems that are more flexible, efficient and resilient.
As industrial digital transformation continues, private cellular networks are likely to play an increasingly important role in enabling the next generation of smart factories.
