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.
Backed by rapid nationwide deployment, a number of LTE smartphones including Vega Racer 2, Galaxy S3 and iPhone 5 and mobile value added services, SK Telecom secured over 11 million LTE subscribers as of June 2013. SK Telecom is the world’s first mobile carrier to launch LTE-Advanced on June 26, 2013 by applying core LTE-Advanced technologies including Carrier Aggregation.
Earlier, SK Telecom said it would build 32,000 units of LTE-Advanced base stations by the end of this year to cover more areas of the 84 cities as well as 300 universities across the nation.
