Frequency supplied extensively without use restrictions
Published2018.01.23 11:20The Ministry of Science and ICT completes the supply of license-exempt frequency band 22~23.6 GHz with 1.6 GHz bandwidth.
This is the first follow-up measure to the "2020 New Industry and Living Frequency Supply Plan" announced at the 3rd meeting of the Fourth Industrial Revolution Committee on December 28, 2017.
Generally, frequency is designated for specific uses such as communications, sensing, and energy applications. However, license-exempt frequency band is a frequency that can be utilized for any purpose without compensation.
Currently, the field expected to benefit most from this band is WiFi backhaul for high-speed mobile platforms such as subways and KTX trains. When utilizing this band, WiFi speeds within subway cars can increase 20 to 100 times faster than current speeds.
This band can be used without allocation fees and wireless station licensing regulations, allowing anyone to freely utilize it for low-cost, ultra-high-speed wireless backhaul construction. However, devices using this band must receive certification to verify they do not cause radio interference with wireless devices used by others.
Ryu Je-myung, Director of Spectrum Policy at the Ministry of Science and ICT, stated, "License-exempt frequency bands have the advantage of allowing new technologies to be developed and applied freely at low cost. Going forward, we will supply frequencies at the right time and place to facilitate new industries utilizing frequency, and make comprehensive innovations to related technical regulations to do our best in expanding wireless infrastructure and services that improve the convenience of people's lives."

KT launches commercial 5Gbps next-generation Wi-Fi service, three times faster than existing Wi-Fi networks.
KT announced that it has completed the development of a next-generation Wi-Fi commercial Access Point (AP) with 5-gigabit-class speeds, approximately three times faster than existing gigabit Wi-Fi, and will launch commercial service on a world-first basis. The next-generation Wi-Fi AP developed by KT utilizes technology based on IEEE 802.11ax standard specifications and applies 8X8 MIMO technology to approximately double the frequency efficiency compared to conventional APs. Additionally, by adopting a 10G internet backhaul solution, stable Wi-Fi service provision is possible even in high-capacity traffic environments. KT has deployed the next-generation Wi-Fi at KT Square in Gwanghwamun and KT Avenue in Gangnam, and will begin commercial service for general customers starting on the 27th.

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.
