South Korean mobile carrier LG Uplus announced that they were the first cellular carrier in the world to deploy uplink 2 carrier aggregation technology (UL 2CC CA) on a commercial network. UL 2CC CA is a key aspect of Huawei's cutting edge technology in its first commercial LTE-Advanced Pro version eRAN11.1 and will give users vastly improved uplink data rate of up to 108 Mbps, which will enable users to upload files much faster on their mobile devices.

LG Uplus and Huawei were able to achieve uplink data rate of up to 108 Mbps on live networks.

Following a series of successful tests on live networks, LG Uplus launched UL 2CC CA technology in step with smartphones supporting uplink carrier aggregation (UL CA).

Background

As the development of smartphones continues in leaps and bounds, HD video and photo have become standard issue in most devices currently being sold on the market. Additionally, smartphone users expect to be able to share their videos and photos across all mainstream social media platforms. This makes it imperative that uplink rates keep up with developments in smart device technology and changing user expectations.

The world's major cellular carriers see uplink data rate as a major bottleneck in improving user experience. In response, they are looking to new and innovative techniques for improving mobile network uplink data rate to meet ever-growing data usage demands, improve user satisfaction, and increase revenues.

Huawei: Innovating for Operators

UL CA aggregates multiple LTE carriers to provide larger bandwidths for improved uplink data transmission rates. This technology will meet the growing demand of HD video and photos sharing anytime, anywhere.

LG Uplus: A Daring Early Adopter

LG Uplus South Korea has always been a proactive innovator with LTE technology, and once again, they have proven themselves on the forefront of wireless network technology. Currently, the cellular carrier is working with Huawei on the world's first commercial deployment of LTE-Advanced Pro based on eRAN11.1. With the large-scale release of commercial devices supporting UL 2CC CA, LG Uplus is the world's first cellular carrier to deploy this technology for commercial use.

This collaboration has achieved great strides in improving uplink data rate. By aggregating an uplink carrier with a 20 MHz bandwidth in the 2.6GHz band and another uplink carrier with a 10 MHz bandwidth in the 850MHz band, LG Uplus and Huawei were able to achieve uplink data rate of up to 108 Mbps on live networks.

Innovations of the Future

Innovations under eRAN11.1 will do much more than improve the uplink user experience for LG Uplus customers. 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.

The future looks bright for MBB users in South Korea, as the first commercial deployment of LTE-Advanced Pro keeps the country on the forefront of wireless network technology. The MBB user experience in South Korea will continue to be one of the best in the world, as users experience the cutting edge of innovation with the ultra-fast speeds of LTE-Advanced Pro.
