Exceeds the maximum LTE speed defined by the ITU
More than 16 times faster than 2011 LTE speeds
| 1.15Gbps Service Launches in 5 Cities Nationwide

SK Telecom announced on the 5th that it will provide 1.2Gbps LTE service with the launch of the Galaxy S10. This exceeds the maximum LTE speed of 1Gbps defined by the International Telecommunication Union (ITU).
Since early 5G services are used in parallel with LTE, LTE innovation is also important for stable 5G services.

Following the launch of the 1Gbps LTE era in February 2018, SK Telecom has once again boosted LTE speeds. A speed of 1.2Gbps allows for the download of a 2GB HD movie in just 13 seconds. This is more than 16 times faster than the initial LTE speeds of 2011.

With the launch of the Galaxy S10, SK Telecom is starting a service with speeds up to 1.15Gbps in traffic-dense areas of five cities, including Seoul, Busan, Ulsan, Gwangju, and Daejeon. This achievement was made possible by applying '4x4 multi-antenna' technology to three frequency bands simultaneously for the first time in Korea.

Wi-Fi has also become faster. SK Telecom provides a Wi-Fi service with a maximum speed of 1.2Gbps based on the Galaxy S10.

The initial Galaxy S10 will offer up to 1.15Gbps, and is expected to support up to 1.2Gbps through a device firmware update within the first half of the year.

SK Telecom has already launched the first 802.11ax standard-based Wi-Fi 6 service in Korea for four devices, including the Galaxy S8, Note 8, Galaxy S9, and Note 9, since September 2018. SK Telecom is the only carrier providing Wi-Fi 6 services of 1Gbps or higher on Samsung Electronics' major flagship phone series.

Locations where commercial network construction has been completed include COEX in Samseong-dong, Seoul, Times Square in Yeongdeungpo, and the Busan Intercity Bus Terminal, while locations scheduled for coverage expansion during the first half of the year include Nambu Terminal in Seoul, Busan Station, and Dongdaegu Station.

SK Telecom has introduced, for the first time in Korea, a technology that divides Wi-Fi channels into smaller frequency bands, allowing multiple customers to connect to a single access point simultaneously. This enables the provision of stable wireless Wi-Fi services by reducing response latency even in high-traffic environments.

“By proactively introducing 1.2Gbps LTE services, SK Telecom customers are now able to experience differentiated communication quality,” said Sung Jin-soo, Head of Infrastructure Solutions Group at SK Telecom. “We will continue to apply next-generation technologies to provide the best network quality in the 5G era.”
