SK Telecom, KT and LG Uplus, which have been in cutthroat competition to improve the quality of their fifth-generation (5G) network services, are now in a race to boost 5G data speeds inside buildings.

Their move comes amid growing complaints over disappointing 5G network coverage since the next-generation mobile network services were launched in early April.

SK Telecom said Wednesday it has completed the development of the "5GX In-building Solution" that is capable of doubling the speed of 5G data transfer inside buildings and effectively dispersing data traffic to prevent overload on base stations in crowded areas such as shopping malls and subway stations.

The nation's top mobile carrier said the new technology will be applied to its commercial 5G networks after the third quarter of the year.

"We expect 80 percent of data traffic to be from inside buildings in the 5G era," said Park Jong-kwan, who heads 5GX Labs at SK Telecom. "We will continue to give efforts to provide users with seamless, high-quality 5G services inside buildings and in crowded areas."

The company said its new system features "Active Antenna" technology that allows 5G small cells, which refer to small indoor base stations, to be equipped with eight transmission and reception antennas.

This will double the speed of 5G data transfer as existing indoor base stations are capable of operating four transmission and reception antennas.

KT has also been working hard to expand 5G coverage inside buildings.

In May, the nation's largest broadband service provider and second-largest mobile carrier interlocked 5G repeaters with commercial 5G networks in cooperation with small and medium business partners.

Installed inside buildings where radio waves from base stations can hardly reach, the device helps improve the quality of 5G services.

KT is in charge of expanding 5G coverage in 95 large buildings out of 119 nationwide, such as airports and KTX stations, in a joint project by the three mobile carriers.

LG Uplus, the smallest player, also has been active in installing repeaters in small and medium buildings and underground parking lots to expand 5G coverage.

The company is planning to expand the application of beam-forming and multi-user MIMO (multiple-input and multiple-output) technologies to its 5G networks nationwide.
