The National Radio Research Agency has developed the world's first measurement system that dramatically improves the accuracy and time of 5th generation mobile communication (28 GHz) antenna performance measurements, and is expected to make a significant contribution to the future growth of the information and communications industry.
The Ministry of Science and ICT announced on the 22nd that the Radio Research Institute (RFRI) has recently succeeded in developing a module, a core component that combines a measurement probe and receiver into a system capable of measuring the performance of 5th generation mobile communication (28 GHz) antennas at high speed, through three years of joint research with domestic universities.
In addition, along with this development, we have completed the construction of a system in Naju and Icheon that can dramatically improve measurement accuracy and measurement time.
Looking at the development progress, in the first year (2019), a 3.5㎓ band measurement system (taking about 100 minutes) was developed, and in the second year (2020), a 3.5㎓/28㎓ dual frequency band measurement system (taking about 30 minutes) was developed to shorten the measurement time. In the third year (2021), the previously developed core component modules were densely arranged in a circular structure to simultaneously measure radio waves emitted from 5th generation (5G) terminals in all directions at 360°, successfully shortening the measurement time to about 12 minutes.
The National Radio Research Agency plans to widely distribute the developed high-speed measurement system and measurement technology to domestic and foreign conformity assessment testing institutions and manufacturers of new 5th generation (5G) technologies in the future.We are pursuing international standardization so that it can be used for product suitability assessment tests, and we plan to form a consultative body involving industry, academia, and research to support commercialization. We also plan to conduct additional research so that this core technology can be expanded to the terahertz band (100 GHz to 10,000 GHz) so that it can be used to complement existing 5th generation (5G) measurement facilities.

European Patent Applications Surpass 200,000 for the First Time… South Korea Maintains 5th Place, Led by Batteries and Telecommunications
According to the European Patent Office (EPO)'s 'Technology Dashboard 2025', European patent applications last year reached 201,974, surpassing 200,000 for the first time. Korean companies and inventors filed 14,355 applications, representing a 9.5% increase from the previous year and maintaining 5th place by country. Battery, digital communication, and semiconductor technologies led the growth, with Samsung ranking as the top EPO applicant for the second consecutive year and LG reaching 3rd place. The presence of major domestic cities such as Seoul, Suwon, and Yongin was also confirmed. It was also revealed that Korea's European patent strategy is expanding beyond individual technologies to span the entire industry.

SK Telecom First Applies AI-Based Network Operations at Gwanghwamun K-Pop Concert
SK텔레콤이 3월 21일 서울 광화문 일대에서 열린 대형 K-팝 공연에 AI 기반 네트워크 운영 시스템을 처음 적용해 통신 품질을 관리했다고 밝혔다. 공연 전후 3시간 동안 모바일 데이터 사용량은 12.15TB로 직전 주말 같은 시간대보다 약 2배 늘었다. SK텔레콤은 AI 시스템 ‘A-One’을 활용해 5분 단위, 50m 단위로 트래픽을 감시하며 과부하 가능성에 대응했고, 임시 통신 시설과 현장 인력 운영도 병행했다. 밀집 행사와 외국인 이용 수요가 동시에 늘어나는 환경에서 AI 기반 자율 네트워크 운영의 현장 적용 가능성을 확인한 사례로 해석된다.
