SK Telecom is strengthening its partnership with Samsung Electronics to provide high-quality 5G services even after 5G commercialization.
SK Telecom is partnering with Samsung Electronics to provide high-quality 5G services even after commercialization.
On the 21st, SK Telecom signed a '5G Differentiating Technology Joint R&D Promotion Agreement' with Samsung Electronics.
The two companies agreed to join forces in the development of 'Mobility Enhancement' technology for the 3.5GHz and 28GHz bands, the development of solutions to expand coverage of the 28GHz band, and the discovery of 5G use cases.
First, Mobility Enhancement technology can improve customer experience quality in 5G heterogeneous frequency operation environments of 3.5 GHz and 28 GHz.
The 28GHz frequency band offers wide bandwidth but short range. While capable of transmitting large amounts of data, the coverage area per base station is limited. Conversely, the 3.5GHz band offers a wide range of radio waves and is therefore primarily used for nationwide network construction. Utilizing both frequencies allows for large data transmission over wide areas.
In October, SK Telecom was the first in Korea to receive approval for a technology standard that can simultaneously use the 3.5GHz and 28GHz bands, which will be used for 5G, as well as LTE frequencies, for data transmission at the 3GPP (3rd Generation Partnership Project) meeting.
Additionally, the two companies will jointly develop solutions to expand coverage in the 28GHz band and continue to advance infrastructure.
In addition, we plan to continue pursuing comprehensive cooperation in a wide range of areas, including 5G use case research and equipment development.
SK Telecom expects that it will be able to provide services such as 5G-based UHD video, augmented reality (AR), and autonomous driving more stably and at ultra-high speeds.
SK Telecom ICT Technology Research Center Director Park Jin-hyo said, “We expect that there will be a great synergy effect as the mobile carriers and manufacturers who are at the forefront of 5G commercialization share technology and know-how,” adding, “Once 5G is commercialized, we will provide the best quality service.”
Samsung Electronics Vice President Kyunghoon Jeon said, “We will experience the dream 5G speed by using not only low frequencies such as 3.5GHz but also ultra-high frequencies such as 28GHz that can secure 800MHz of wide bandwidth,” and “Samsung Electronics will provide the best network quality based on its advanced technology in both low frequencies and ultra-high frequencies, and we will also cooperate to discover new services by utilizing ultra-high frequencies such as 28GHz.”
Meanwhile, the signing ceremony held on the 21st at T Tower in Euljiro, Seoul was attended by SK Telecom ICT Technology Center Director Park Jin-hyo, N/W Technology Center Director Park Jong-kwan, and Samsung Electronics Network Business Division Vice President Jeon Gyeong-hun.

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.
