Following Samsung's release of a Galaxy S4 with the Snapdragon 800 SoC and LTE-Advanced support -- the first smartphone in the world with LTE-A support -- SK Telecom has launched the world's first LTE-Advanced network in South Korea. The new network, which is technically the world's first true 4G network, is capable of download speeds of 150Mbps. A download speed of 150Mbps is about twice that of normal LTE, or around 10 times the max speed of 3G. According to SK Telecom, users will be able to download an 800MB movie in 40 seconds using the new network.
