Communication technology enabling connectivity even on high-speed KTX trains leads 5G standardization
Published2017.07.18 16:15Technology reflected in ITU and 3GPP documents
Leading 5G mobile communication standardization with mobile wireless backhaul (MWH) technology successfully demonstrated on moving subway trains.
The Electronics and Telecommunications Research Institute (ETRI) announced that at an international standardization conference held in Niagara Falls, Canada at the end of last month, it reflected millimeter-wave-based high-speed mobile environment technology in the IMT-2020 evaluation document so that it can be evaluated as a 5G technology.
This decision was made at the 27th International Telecommunication Union Radiocommunication Sector (ITU-R) mobile communication working group meeting promoting standardization.
The technology reflected by ETRI uses millimeter-wave (30GHz) to enable gigabit-class (Gbps) mobile communication in high-speed mobile environments such as KTX trains utilizing millimeter-wave-based technology. China and Japan collaborated jointly in reflecting this evaluation document.
The fact that ETRI's developed technology is reflected in ITU and 3GPP evaluation documents means it is substantively being reflected in 5G standardization. In other words, it has laid the foundation for key core technologies of MWH to be approved as 5G technologies.
Subsequently, ITU will begin accepting 5G candidate technologies starting from meetings in October, and Korea is preparing to submit letters of intent for domestic 5G candidate technologies according to the 5G leadership strategy and to propose 5G candidate technologies.
Researchers anticipate that the reflection of this ITU evaluation document will serve as a foundation for developing 5G mobile communication technologies for convergence services between different business sectors, and through ITU standards, international cooperation among nations can be expanded.
Jung Hyun-kyou, head of ETRI's 5G Gigabit Service Research Division, stated, "The reflection of this MWH technology in the evaluation document has significant meaning as a report that establishes evaluation criteria among nations. It is equivalent to laying the cornerstone toward future 5G international standards."

ETRI to Develop Technology to Track Criminals Using CCTV AI
ETRI (Electronics and Telecommunications Research Institute) announced on the 1st that it will undertake development of a cloud-based intelligent video security incubation platform. This technology, by learning and providing intelligent public safety models optimized for diverse security environments based on a cloud platform, is expected to significantly contribute to strengthening market competitiveness through securing intelligent core technology for small and medium-sized video-related companies, as well as constructing next-generation advanced public safety platforms. Existing CCTV systems installed are widely utilized in crime resolution by providing decisive evidence; however, there are many situations where accurate identification by the naked eye is difficult. As a single operator monitors dozens of CCTV channel feeds over extended periods, there are cases where dangerous situations go undetected even when they occur. ETRI will develop next-generation advanced public safety technology by integrating artificial intelligence technology into security CCTV systems to automatically detect dangerous situations such as traffic accidents and crimes in real-time, alert police, and automatically identify and track suspects and vehicles related to incidents.

ETRI uses sensors to analyze movement and create vibrations to help correct posture.
ETRI has developed a technology that attaches 17 sensors and 10 actuators to major joints on the human body to learn and 3D analyze and compare the movements of a target and the user, providing vibration signals for correction when movements are performed incorrectly. The research team explained that this technology can determine joint angles and three-dimensional positional coordinates through data values obtained from sensors installed at each of the 17 joints. When worn as clothing or attached as a band, it assists with spinal posture correction during exercise movements and rehabilitation therapy.

ETRI Establishes Dedicated Organization to Support Open Source Activities
ETRI (Electronics and Telecommunications Research Institute), a government-funded research institute, has launched its first dedicated open source software organization. Open source software refers to software whose source code is publicly disclosed and can be modified and adapted by anyone. The institute plans to oversee open source policy establishment and response management, which will become increasingly important in the future through this organizational expansion. ETRI announced the establishment of the "Open Source Center," a dedicated organization capable of addressing and supporting open source activities. With the recent shift toward an open paradigm, the influence of open source has grown significantly, and there is a trend of expanding applications across all ICT fields. Representative examples of open source software include Linux and Android. At the government level, active efforts are being made to recommend open sourcing of research results to improve technology utilization rates and commercialization success rates relative to budget investments in national R&D projects. In fact, strategies utilizing open source are becoming increasingly prominent in the actual market. Particularly in fields such as the Internet of Things (IoT), open source is being developed alongside standards and employed as a global business strategy to accelerate early market penetration.

SK Telecom First Applies AI-Based Network Operations at Gwanghwamun K-Pop Concert
SK Telecom announced that it applied an AI-based network operation system for the first time at a large-scale K-pop concert held in the Gwanghwamun area of Seoul on March 21st, managing communication quality throughout the event. Mobile data usage during the three hours before and after the concert reached 12.15TB, approximately doubling compared to the same time slot the previous weekend. SK Telecom monitored traffic using the AI system 'A-One' in five-minute and 50-meter units to respond to potential overload situations, while also operating temporary communication facilities and on-site personnel in parallel. This case is interpreted as confirmation of the practical applicability of AI-based autonomous network operation in an environment where demand from dense events and foreign users increases simultaneously.
