Sejong Telecom announced on the 18th that it has successfully established the country's first shared core 5G model at a construction site.
In July, Sejong Telecom signed a business agreement with Kolon Global and Hurean for the application of a smart safety management system using 5G. This project is a demonstration project carried out as part of the '5G B2B service activation' national agenda organized by the Ministry of Science and ICT and the National Information Society Agency (NIA).
In this project, Sejong Telecom is responsible for the construction of the core shared 5G model and operation of the control center at the Asia-Pacific Bio Processing Production Center construction site of Merck Life Science, managed by Kolon Global. The Merck Bio Center is a raw material production facility used in bio processes and is being built on a scale of 43,000 square meters (approximately 13,000 pyeong) in Yuseong-gu, Daejeon, with completion expected in early 2026.
The shared core 5G model is a technology that shares the core of the 5G main center across multiple sites, providing a model for reasonably constructing 5G at each site. This helps improve communication errors and shadow areas that occurred when using LTE or Wi-Fi, aiding effective on-site safety management.
Sejong Telecom, in collaboration with Hurean, a smart safety management solution corporation, has refined the types of essential services based on Kolon Global's requirements and finalized the service areas for constructing the smart safety management system at the construction site. The services include three main components: high-quality CCTV video control, smart safety management platform, and smart safety equipment.
The high-quality CCTV video control is characterized by its ability to innovate situational awareness on-site through the transmission of high-resolution, large-volume video data and enhancement of AI video analysis based on the ultra-fast and ultra-low latency technology of 5G. Additionally, the network coverage for installing CCTV has been expanded with 5G, allowing the installation of both fixed and mobile AI CCTVs throughout the site. Combining the latest AI algorithms and deep learning into the CCTV video analysis technology helps facilitate immediate actions by detecting frequently occurring accidents and abnormal situations and transmitting this information to the smart safety management platform.
With the use of the smart safety management platform based on 5G, security has also been significantly enhanced. This is because it can be configured so that construction site videos can only be viewed on tablets and laptops with authorized USIMs distributed by the construction company. Access to the video is blocked once outside the 5G area, alleviating concerns about video leakage. Through a cloud-based monitoring system, real-time access is enabled, and safety situations and data can be checked anytime and anywhere on-site. The smart safety management platform based on 5G is also applicable for linking construction video record management to prevent poor construction, analyze causes, and establish countermeasures in case of accidents.
Additionally, through the establishment and integration of smart safety equipment dedicated to 5G, such as collapse and displacement warning devices, combined gas and temperature/humidity sensors, and flame fire detectors, efforts have been intensified to prevent safety accidents across the entire construction site.
The control center located at Sejong Telecom's headquarters in Gwacheon has installed the 5G main core and service management platform to process control signals from remote locations and to carry out system operations such as equipment management and user management.
The 5G solution from HFR Mobile has been applied to this project. HFR Mobile has supplied 5G solutions to mission-critical sites where stability is emphasized, such as Korea Hydro and Nuclear Power Corporation and Japan's Hanshin Railway, proving its stability and technological competence.
Baek Gi-young, GM of Sejong Telecom, who performed this task, was recognized for his contributions to expanding 5G technology and convergence services and received the Minister's Award from the Ministry of Science and ICT at the '5G Industry Convergence Foundation Achievement Sharing Session' held on the 17th.
Baek Gi-young, GM of Sejong Telecom, noted, "5G is effective not only in ultra-fast and ultra-low latency communication but also in improving technology security and industrial accident issues. In particular, the model that shares the 5G core will significantly reduce the investment expense for the introduction of 5G at construction sites and greatly enhance efficiency relative to investment."
