The South Korean government said Wednesday it will expand coverage of the fifth-generation wireless network, with a goal of providing the service to more than 90 percent of the population by the end of this year.

A day after the meeting with mobile carriers Tuesday, the Ministry of Science and ICT said the carriers had pledged to build a total of 230,000 5G base stations in 85 cities, covering 93 percent of Korea’s total population of around 51 million.

According to the ministry, 50,512 5G stations have been established as of Monday since the country launched the network’s commercial service on April 5. However, most are concentrated in Seoul, its surrounding areas and other metropolitan cities.

In addition to expanding 5G infrastructure to rural areas, the government said it will make the network available at indoor and underground facilities. The mobile carriers vowed to build 5G equipment on every line on the Seoul subway and at 120 large buildings nationwide.
