담당부서 작성자 연락처

The Ministry of Science and ICT (Minister Lim Hyesook, MSIT) announced the result of the 28 gigahertz subway Wi-Fi backhaul demonstration and its expansion plan, and pilot-launched a scheme that enables the sharing of commercial 5G network in rural areas in cooperation with the country’s three major mobile carriers—SK Telecom, KT Corp. and LG Uplus—in an effort to provide 5G network access to all Koreans, on November 25.

Minister Lim Hyesook of Science and ICT encouraged the mobile carriers to expand their investments to secure network stability and quickly improve 5G service quality, and the mobile carriers agreed to maintain investments at the previous year’s level by the year’s end.

In particular, Minister Lim emphasized further efforts to improve the quality of subway Wi-Fi using the 28㎓ spectrum, since it can bring tangible impacts to many. To resolve the issue of poor Wi-Fi quality in subway trains, the MSIT and three major mobile carriers worked together to improve the quality of service by conducting demonstrations using 5G 28㎓ spectrum in parts of subway Line 2. With the demonstrations proving that subway Wi-Fi is approximately 10 times faster than the current speed, Wi-Fi operating on 28㎓ spectrum will be expanded to major subway lines including Line 2, 5, 6, 7 and 8.

In another line of effort to achieve nationwide 5G, the MSIT is pursuing a scheme in which the three major carriers share 5G networks in rural areas such as farming and fishing communities so that the residents can enjoy 5G services in the near future. This scheme won the “5G Industry Partnership Award” from 2021 Global Mobile (GLOMO) Awards hosted by the Mobile World Congress (MWC).

A pilot project of the scheme will be carried out in 12 rural areas across the country, with the first stage of piloting beginning by 2022 and gradually expanded to fully deploy 5G network services by the first half of 2024.

Minister Lim said, “The Ministry will ensure that the successful subway Wi-Fi demonstrations can be replicated, and deploy shared 5G network in rural areas without delay. Along with this, the MSIT will secure network stability and enhance the quality of service through expanding investments on 5G. This will enable everyone to enjoy the benefits of 5G network services and furthermore, contribute to making Korea an inclusive digital society.”
