SEOUL -- Naver Cloud, a cloud computing service wing of South Korea's top web portal operator and IT company, has become the country's first operator of a "private 5G" network customized for services in specific regions that affords numerous advantages for modern enterprises as it can deliver ultra-low latency and incredibly high bandwidth connections supporting artificial intelligence-driven applications.

The Ministry of Science and ICT said that Naver Cloud was registered as South Korea's first company to provide a telecom service using a private 5G network. The move is aimed at expediting the creation of various mobile telecom businesses using private 5G networks in South Korea. Without borrowing 5G networks built by mobile carriers for businesses in factories or buildings, companies that want to provide 5G-based convergence services can build private 5G networks in specific regions. 

"As we focused on starting a new private 5G service, 2022 will be the first year that e-Um 5G will spread in earnest," Cho Kyeong-sik, the science ministry's 2nd vice minister, said in a statement on December 28.  "As can be seen from Naver Cloud's case, we hope companies will discover various 5G convergence services by connecting all devices into one using private 5G networks."

The ministry will provide the 28 gigahertz (GHz) band for private 5G networks. South Korea has commercialized a 5G mobile telecom service using the frequency band of 3.5 GHz. Full-scale 28 GHz 5G networks that make data transmission speed faster especially in areas where traffic is concentrated are still in the experimental stage.

Unlike mobile telecommunication companies that developed nationwide business-to-consumer (B2C) communication businesses based on frequency monopoly rights, the ministry said that private 5G network operators can use regional monopoly rights to conduct business-to-business (B2B) communication services in limited areas.

Naver Cloud will work with Naver Labs in charge of AI, robot and autonomous technology to establish a smart office using a private 5G network at a new robot-friendly building under construction in Bundang in the southern satellite city of Seoul where 5G "brainless" robots controlled by a cloud system will coexist with human workers.
Using private 5G's ultra-high-speed and ultra-low-latency characteristics, hardware and software for local AI execution can be removed from robots, leading to reduced manufacturing costs and battery consumption. For services to other companies, Naver Cloud will provide cloud data centers and private 5G networks, while Naver Labs will offer ultra-large AI and 5G brainless robots.

Naver will use the robot-friendly building as a global reference space where 5G networks, cloud, robots, autonomous driving, digital twin, and AI are connected and fused into one. Employees would experience new workspaces, such as access to space through face recognition and delivery using autonomous robots. Contactless orders will be possible in restaurants and cafes. Robots will receive parcels and bring them to the seats of employees.
