Hyundai and Samsung Bring RedCap Private 5G to Smart Manufacturing

Posted by on

Private 5G networks are redefining industrial automation, and Hyundai Motor Company, in collaboration with Samsung Electronics, is at the forefront of this transformation. The two companies have successfully completed an industry-first trial of Reduced Capability (RedCap) technology over a private 5G network, bringing new efficiencies and cost savings to smart manufacturing.

Private 5G: A Game Changer for Hyundai’s Smart Factories

Hyundai has already integrated private 5G (P5G) into mass production at its Ulsan Plant, the world’s largest single automotive manufacturing facility, and Hyundai Motor Group Metaplant America (HMGMA). This latest RedCap verification marks another leap forward, proving that private 5G can support not only high-performance industrial automation but also a wider range of smaller, lower-power devices.

P5G provides dedicated, interference-free connectivity for factory operations. It enables seamless data transmission for centralized control of industrial robots, automated guided vehicles (AGVs), and IoT sensors. Compared to traditional Wi-Fi-based factory networks, private 5G delivers higher speeds, lower latency, and more reliable connectivity—essential for modern smart manufacturing.

What Makes RedCap Special?

RedCap (Reduced Capability) technology is designed to streamline 5G for smaller industrial devices like sensors, cameras, and inspection tools. Until now, private 5G was primarily used for high-performance equipment, but RedCap expands its reach to battery-operated, cost-sensitive devices.

Hyundai integrated Qualcomm’s Snapdragon X35 5G Modem-RF System into its Diagnostic Scan (D Scan) system, enabling real-time wireless vehicle inspections. This ensures that every assembled vehicle meets quality standards before leaving the production line, something that was previously difficult with Wi-Fi due to interference and connection instability.

With Samsung’s RedCap-powered private 5G solutions, Hyundai achieved:

  • Lower power consumption for IoT devices
  • Increased uplink capacity for real-time data transmission
  • Enhanced automation and monitoring across smart factory operations

Expanding the Future of Smart Manufacturing

The successful RedCap trial is a stepping stone for Hyundai’s broader vision of private 5G-enabled smart manufacturing. Looking ahead, the company plans to integrate P5G into its new EV-dedicated plant in Ulsan, opening in 2026. This expansion will further solidify private 5G’s role in improving operational efficiency and enabling seamless factory automation.

The adoption of RedCap is also expected to drive broader 5G adoption across industries, from construction and logistics to healthcare and academia. As private 5G networks evolve, they will power an increasing number of industrial applications, making digital transformation more accessible and cost-effective.

Conclusion

Hyundai and Samsung’s collaboration on private 5G RedCap technology is a testament to how innovation in connectivity can unlock new possibilities in manufacturing. By leveraging RedCap’s efficiency and cost benefits, Hyundai is not just enhancing its own production capabilities but also setting the stage for the next generation of smart factories worldwide.

As private 5G adoption grows, expect to see more industrial leaders following Hyundai’s example, bringing next-generation connectivity to factories, supply chains, and beyond.
