MWC: SK Telecom achieves 450Mbps speeds in three-band CA LTE-A test

28 Feb 2014

SK Telecom showcased its LTE-Advanced (LTE-A) three-band carrier aggregation (CA) technology to TeleGeography at the Mobile World Congress (MWC) in Barcelona this week, delivering download speeds of 450Mbps. The speeds were achieved by aggregating three component carriers (20MHz each). The technology, which could be commercialised as early as end-2014, is capable of downloading an 800MB movie in just 14 seconds.

In June 2013 SK Telecom rolled out the world’s first LTE-A network offering carrier aggregation, and successfully supports downlink data speeds up to 150Mbps, twice the 75Mbps it was delivering over its LTE network without aggregation. In November 2013 the company went on to demonstrate transmission speeds of 225Mbps via 10MHz+20MHz CA.
