SK Telecom announced the world’s first consumer LTE-Advanced network today, and it’s quick. This new standard is the successor to the current-generation LTE technology, and supports much higher data transmission speeds – downloads top out at 102Mbps, ten times faster than the average home broadband speed in the US. And SK Telecom is rolling the new service out to customers free of charge. The service will be available by the end of the year, and the first device to take advantage will be the Galaxy S4 LTE Advanced. With the rest of the world just getting a taste of LTE, Korea remains several steps head of the mobile world.
