Hyundai Motor and Samsung are collaborating to verify Private 5G (P-5G) RedCap technology. This will enable faster communication with lower power consumption and cost. Hyundai’s Ulsan Plant in South Korea and Hyundai Motor Group Metaplant America (HMGMA) in Georgia are pioneering P-5G in mass production. The company also has plans to expand P-5G use to a new EV-dedicated plant in Ulsan.

P-5G is a dedicated system installed on-site using a specific frequency band, ensuring no external interference and seamless data transmission for smart manufacturing with centralised control of industrial robots and devices. It can be tailored for optimised environments and stable communication, though challenges like complex design and high power consumption remain.

Since January 2025, Hyundai Motor has completed testing of Samsung’s P-5G solutions including radio, core, and management systems with its in-house vehicle inspection equipment at Samsung’s Suwon campus. They developed a custom vehicle inspection device to verify the network’s operational capabilities.

The collaboration successfully verified the P-5G RedCap technology, which offers simplified device configurations, compact infrastructure, and reduced bandwidth usage. This results in lower power consumption, cost efficiency, and improved performance over traditional Wi-Fi in speed, data processing, connection stability, and low latency.

Previously limited to high-performance equipment, RedCap technology enables high-speed wireless communication for vehicle inspection equipment, small tools, cameras and tablets. Hyundai Motor integrated RedCap enabled Qualcomm’s Snapdragon X35 5G Modem-RF System chipsets into its Diagnostic Scan (D Scan) system for efficient vehicle inspection data transmission via Samsung’s 5G network.

Samsung’s P-5G solution, with support for optimised RedCap software, reduces power consumption and more than doubles uplink capacity for real-time IoT data transmission, featuring an integrated management system for automation.

“Hyundai Motor was the first Korean company to implement P-5G in mass production,” said Jae Min Lee, Vice President and Head of E-FOREST Center of Hyundai Motor and Kia. “We are also the industry’s first to verify P-5G RedCap technology, reinforcing our global leadership in smart manufacturing solutions. We will continue to accelerate its commercialisation.”

Simon Lee, Vice President and Head of B2B•B2G Business Development, Networks Business at Samsung Electronics said: “The recent collaboration with Hyundai Motor represents how the two leaders in their respective industries can creatively drive business innovation and unlock new real use cases by merging best-in-class expertise. Samsung’s RedCap-powered private 5G network solutions will open up more possibilities for enterprises, manufacturers, and public institutions, serving as a gateway to driving more efficient 5G networks.”

Hyundai Motor is also planning to integrate P-5G into its new EV-dedicated plant in Ulsan, opening in 2026.
