SK Telecom introducing 225Mbps LTE-A this week

18 Jun 2014

SK Telecom (SKT), South Korea’s largest cellco by subscribers, is gearing up to introduce Long Term Evolution-Advanced (LTE-A) technology this week, CNET reports, allowing it to offer end-users maximum theoretical download speeds of 225Mbps. The LTE-A broadband service utilises carrier aggregation (CA) technology, which combines 10MHz and 20MHz spectrum blocks to triple the 75Mbps speeds it delivers over its LTE network without aggregation. Further, the first handset to support LTE-A speeds has been unveiled as Samsung’s flagship smartphone – Samsung Galaxy S5 LTE-A – which will be available exclusively on SKT’s network. Manufacturers LG Electronics and Pantech are also planning to debut new LTE-A compatible devices by early-July.

As previously reported by CommsUpdate, the company first demonstrated transmission speeds of 225Mbps via 10MHz+20MHz CA in November 2013. Further, in February 2014 SKT showcased its LTE-A three-band CA technology to TeleGeography at the Mobile World Congress (MWC) in Barcelona, delivering download speeds of 450Mbps. The speeds were achieved by aggregating three component carriers (20MHz each).
