SKT cranks LTE-A up to 225Mbps

Maintaining its technological edge, South Korea’s SK Telecom on Thursday announced that it has commercialized 225Mbps LTE-Advanced – three times as fast as 75Mbps LTE – for the first time in the world.

The carrier upgraded LTE-Advanced, which provides up to 150Mbps, by applying Carrier Aggregation (CA) technology that binds 20MHz bandwidth in the 1.8GHz band and 10MHz bandwidth in the 800MHz band. At its peak speed, customers are able to download a 1GB movie in 37 seconds.

SK Telecom introduced LTE-Advanced last June, three years on from the nation’s first LTE commercialisation in July 2011.

In order to make use of the network speed, SK Telecom introduced Angles, a social multimedia service, that allows high-definition video files filmed from different angles by up to four users to be automatically edited into one single file in the cloud then to be viewed and shared on smartphones.

The company will also unveil Cloud Game, a cloud-based streaming game platform, on June 24. Cloud Game will run on a cloud server so that users can enjoy it on smartphones in a real-time with ultra-high definition, ultra-high volume and multiplayer games.

The 9th annual LTE Asia conference is taking place on the 15th-17th September 2014 at the Suntec, Singapore. Click here to download a brochure for the event.

The company also beefed up video content as well. At the end of last May, SK Telecom and SK Broadband started the world’s first UHD service on ‘B tv mobile’. UHD content is four times the resolution of full HD.

The SamsungGalaxy S5 is optimised for the new service and goes on sale Thursday.

SK Telecom’s customers will not be charged extra for the 225Mbps LTE-Advanced service and at the end of June, SK Telecom will introduce the ‘Subway Free’ plan, an optional data plan to allow unlimited data use in subways and subway stations in Seoul and the metropolitan area at 9,000 KRW a month.

    There are some erroneous claims in this article. A standard 20MHz LTE FDD carrier has a theoretical peak speed of around 150MBit/s. SKT can deliver this speed on their standard 1800Mhz network. Carrier aggregation, a feature of LTE-A (there is no such thing as upgraded LTE-A) allows SKT to combine the 75Mbit/s they achieve in a standard 10MHz carrier at 800Mhz to a perfectly standard 225Mbit/s.
    Yes, 225Mbit/s is 3x as fast as 75Mbit/s but it is a pointless claim considering they could do 150Mbit/s already?!
