Sprint's chief network officer, John Saw, said the company plans to deploy carrier aggregation across portions of its Spark network late this year that should improve theoretical maximum download speeds to 120Mbps. Sprint will add a third channel to this planned two-channel configuration by the end of 2015 that it says will boost theoretical download speeds to 180Mbps. Sprint Spark is the company's tri-band LTE network that offers faster speeds than the rest of Sprint's LTE network. The company has launched Spark in 18 markets so far, and plans to cover 100 million POPs with Spark by the end of the year. Saw didn't saw which markets might be first to see the speed bump. Sprint Spark currently offers max download speeds of about 50Mbps, with real-world speeds averaging between 12 and 15Mbps.
