KT Successfully Achieves 25Gbps 5G Transmission in Wireless Environment Using mmWave
Published2016.02.18 17:21Utilizes Wide Frequency Bandwidth from Hundreds of MHz to Several GHz Units
KT announced on the 17th Swedish local time that it successfully achieved data transmission at 25.3Gbps speed in the world's first 'multi-user wireless environment' jointly with Ericsson using Millimeter Wave (mmWave). mmWave is a promising candidate frequency band for 5G mobile communication services that can implement high transmission speeds by utilizing wide bandwidth.
Because mmWave has an extremely small wavelength, equipment miniaturization is possible, and it can utilize wide frequency bandwidth from hundreds of MHz to several GHz units. Therefore, it is essential for achieving transmission speeds of 20Gbps or higher, which are the 5G performance requirements presented by the International Telecommunication Union (ITU) in June 2015.

Unlike previous technology demonstrations that implemented transmission speed in a wired connection method to a single terminal, KT successfully showcased multi-user MIMO (Multiple-Input Multiple-Output) based transmission technology of 25Gbps or higher in a multi-user wireless access environment for the first time in the world. This represents a level capable of transmitting data at speeds 80 times faster or more than existing LTE-A.
KT is targeting trial 5G services at the 2018 PyeongChang Winter Olympics, and for this purpose is developing PyeongChang 5G system specifications in cooperation with global manufacturers. Some of the specifications are reflected in the mmWave system successfully demonstrated this time.
KT has already established the foundation for 5G technology by demonstrating transmission speeds of 7.55Gbps using mmWave at MWC 2015, and through MWC 2016 plans to demonstrate transmission technology of 20Gbps or higher, showcasing KT's leadership in 5G technology beyond Korea to the entire world.
Lee Dong-myeon, Director of KT's Mobile Convergence Technology Institute, stated: "This successful 25Gbps mmWave wireless demonstration is the result of KT's continuous commitment to 5G research and development. We are also conducting ongoing research in 5G common specifications that will lead to global standards and various 5G core technology areas. Going forward, we will continue to lead global 5G wireless communication technology while presenting genuine 5G first-class technology and services that customers can experience. And at the upcoming PyeongChang Winter Olympics, we will provide fast and stable trial services utilizing full-scale 5G mobile communication technology."

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.
