The fixed-line subsidiary of wireless carrier SK Telecom said it achieved the speed using GPON technology as an alternative to Ethernet.
GPON can provide up to 52.5Gbps speed with one cable, or one core, and host 128 subscribers, SK Broadband said.
When multiple devices such as smartphones, tablets, and AI speakers are used, each device will get a maximum internet speed of 1Gbps.
On average they will enjoy a speed of 833Mbps, three times that of competing 333Mbps, the company said.
Current coverage is 40 percent but it will invest 1 trillion won going forward to expand this to 80 percent by 2020.
SK Broadband will roll out 5Gbps and 10Gbps internet services in the second half of the year, which will also use GPON technology.
The South Korean government will pick two consortia for projects that will help fast-track the commercialisation of 10-gigabit (Gb) internet. »
