South Korean mobile carrier, LG Uplus claims that it is the first cellular carrier in the world to deploy uplink two carrier aggregation technology (UL 2CC CA) on a commercial network. LG Uplus and Huawei were able to achieve uplink data rate of up to 108 Mbps on live networks supported by smartphones with the technology.
UL CA aggregates multiple LTE carriers to provide larger bandwidths for improved uplink data transmission rates. This technology will meet the growing demand for data intensive applications such as HD video and photo sharing.
According to Huawei, the UL 2CC CA is a key aspect of its commercial LTE-Advanced Pro version eRAN11.1 and will give users vastly improved uplink data rate, which will enable users to upload files much faster on their mobile devices.
After commercial deployment of downlink 3 carrier aggregation (DL 3CC CA), LG Uplus is sparing no effort in exploring new business opportunities under LTE-Advanced Pro, and is currently conducting joint testing of 256QAM to improve downlink data rate.
