South Korea is about to get a taste of what true 4G mobile broadband speed is. SK Telecom announced Wednesday that it has launched the world's first LTE-Advanced network, a faster LTE standard that was originally deemed by the International Telecommunications Union as a true 4G standard. LTE-Advanced is capable of data transfer rates of 150Mbps, roughly twice as fast as the 4G LTE speeds available in the United States and elsewhere, and 10 times faster than 3G, SK Telecom said.
