The LTE-A service offers download speeds of up to 150 Mbps, which is two times faster than its regular LTE service, and 10 times faster than its 3G network. LTE-A coverage initially is available in Seoul and central city areas of Gyeongg-do and Chungcheong-do. Expansion to 84 cities nationwide is planned.
At top speed, LTE-A users can download an 800MB movie in just 43 seconds.
The LTE-A implementation leverages several advanced mobile network technologies including Carrier Aggregation (CA) and Coordinated Multi Point (CoMP). SK Telecom plans to implement Enhanced Inter-Cell Interference Coordination (eICIC) in 2014.
CA supports up to 150 Mpbs speed by combining two 10 MHz components carriers to form an effective bandwidth of 20 MHz. The company said further advancements should yield rates up to 300Mbps speed by aggregating two 20MHz component carriers by 2015, and become capable of combining three component carriers by 2016. An uplink capability using carrier aggregation should also be possible by 2016. The current CA standards allow for up to five 20 MHz carriers to be aggregated.
SK Telecom is offering LTE-A service at LTE prices. Customers will not have to pay more for the faster service.
Samsung's Galaxy S4 LTE-A smartphone is the first compatible device It will come in two colors, red (exclusively available at SK Telecom) and blue. The operator has secured an initial supply of 20,000 units of Galaxy S4 LTE-A. SK Telecom expects to have seven LTE-A devices on offer later this year.
SK Telecom' LTE-A phones will feature embedded services like 'Safe Message' and 'Safe Data Backup'. Safe Message is designed to protect users from smishing (SMS phishing) attacks by enabling them to check whether the message is sent from a trusted source; and 'Safe Data Backup' enables users to upload personal data stored in their smartphones to the cloud server to keep data safe from smartphone loss and accidental deletion. The company also plans to mount these features on all its to-be released LTE phones as well.
