Huawei and South Korea\'s mobile operator LG Uplus have run a joint commercial network trial of three different band Carrier Aggregations (3CC CA), Lteworld.org reports, noting that LG Uplus already has 7.5 million LTE subscribers across three commercial LTE network bandwidths - 800-MHz, 2,100-MHz and 2,600-MHz.

CA is a key LTE-Advanced technology that combines two or more basic bands to meet higher throughput demand and deliver faster data speeds, improving overall network capacity, and providing a more seamless user experience.

The technology will be supported by 3CC CA technology-compatible smart phones later this year. LG Uplus and Huawei held a joint demonstration of 3CC CA solutions at the Mobile World Congress 2014, after which the operator had 3CC CA ready for commercial use and now plans to deploy advanced technologies, such as Intelligent Carrier Aggregation, for better user experiences.
