SK Telecom demonstrates up to 225Mbps speed with upgraded LTE-Advanced service

Mobile service provider SK Telecom on Thursday demonstrated up to 225Mbps of speed with its upgraded LTE-Advanced service.

The Korean telecoms enhanced the LTE speed by aggregating 20MHz bandwidth in 1.8GHz band and 10MHz bandwidth in 800MHz band.

Using a maximum of 20MHz of continuous spectrum in one band, LTE can only offer up to 150Mbps of speeds.

The company expects to launch the 20MHz+10MHz LTE-Advanced service nationwide through smartphones in the second half of 2014 as the smartphone chipset that supports 225 Mbps of speeds is currently being developed.

Utilizing SK Telecom’s upgraded LTE-Advanced (20MHz+10MHz), customers can download an 800MB movie in 28 seconds. Downloading the same movie file via 3G, LTE, and the existing LTE-Advanced (10MHz+10MHz) would take 7 minutes and 24 seconds, 1 minute and 25 seconds, and 43 seconds, respectively.
