South Korea's ICT ministry and its wireless service providers SK Telecom Co., KT Corp., and LG Uplus Corp will test millimeter wave (mmWave) 5G technology in the Seoul subway system to improve network services and speed up commercialization.
South Korea's 5G networks are currently deployed on the relatively slower mid-band spectrum than on the high-band mmWave spectrum, which can be up to 20 times faster than 4G LTE.
Establishing a backhaul network based on mmWave 5G on the Seoul subway system is expected to drastically improve Wi-Fi services.
The carriers will test the technology across a 5.4-kilometer section on Line 2 from Sinseoldong Station to Seongsu Station with network equipment from Samsung Electronics Co.
The government is seeking to encourage mobile carriers to invest more in improving 5G services as it aims for the network's nationwide coverage by the end of next year.
Carriers have been reluctant to commercialize mmWave 5G amid a lack of services that can fully utilize what the technology can offer. They are currently testing mmWave 5G services focusing on business applications, such as autonomous delivery robots and live video feeds of sports games in virtual reality.
About 71 percent of South Korea's mobile users were still on 4G networks as of April, with 21 percent on 5G.
Average 5G download speeds were around four times faster than 4G LTE last year.
