Korea's SK Telecom has successfully developed "LTE-Advanced 3 Band Carrier Aggregation (CA)" technology for the first time in the world.
The technology the company unveiled today aggregates 3 bands - 20MHz+10MHz +10MHz - to support speeds of up to 300Mbps.
Industry experts forecast LTE-Advanced 3 band CA to become commercialized in the end of 2014.
Global standardization process for LTE-Advanced 3 band CA is currently underway.
SK Telecom plans to showcase its LTE-Advanced 3 band CA at MWC 2014, to be held in Barcelona next month. At this global exhibition, the company will demonstrate 450Mbps LTE-Advanced by aggregating three component carriers (20MHz+ 20MHz+20MHz).
Sprint has also demonstrated 1.3Gbps mobile broadband speeds in a lab setting and believes it can eventually hit 2Gbps.
