South Korea's SK Telecom says that it has upgraded its LTE A network to support theoretical peak download speeds of up to 225Mbps.

SK Telecom upgraded the existing LTE-A which provides up to 150Mbps by applying Carrier Aggregation (CA) technology that binds 20MHz bandwidth in 1.8GHz band and 10MHz bandwidth in 800MHz band.

SK Telecom described the world's first commercialization of 225Mbps LTE-A a remarkable accomplishment that would further raise the status of Korea as an ICT powerhouse. Among 300 network operators with commercialized LTE across 107 countries, SK Telecom is the first to implement 225Mbps LTE-A technology on network systems and smartphones for commercialization.

Furthermore, by successfully commercializing the '20MHz+10MHz' CA, SK Telecom moves one step closer to realizing the next level of LTE-A technology: 3 band LTE-A by aggregating three component carriers.

From today, 225Mbps LTE-A is available to users of a smartphone compatible with SK Telecom's 225Mbps LTE-A in Seoul, its metropolitan area and all other metropolitan cities, and from July in all regions across the country where either 20MHz LTE or LTE-A is in service.

The company plans to provid 225Mbps LTE-A service all across the nation from July.

The first smartphone to be sold that will support the higher speed will be a modified version of the Samsung Galaxy S5
