2014 Mobile World Congress: SAMSUNG Demonstrates the Company’s Carrier Aggregation Technologies

Samsung Electronics Co., Ltd attended the 2014 Mobile World Congress, in order to showcase the company’s developments in Carrier Aggregation or CA. The evolutions of the Carrier Aggregation included improvements in several aspects all at the same time, including:

• Better Heterogeneous Network (HetNet) Management
• Diverse Technology Use Cases
• Improved Cell Edge Performance
• Innovative Technologies
• Powerful Data Off-loading Capability’s Large Coverage
• Significant Mobile Data Speed Enhancements

A feature of LTE-Advanced, the heterogeneous networks are all powered by the company’s Carrier Aggregation technologies.

In the first state of demonstration at the 2014 Mobile World Congress, SAMSUNG featured the company's 3Band CA ,which is normally composed of three carriers, each carrying 20MHz. In the company’s demonstration, the 3Band CA showed its total data, which sums up to a maximum of 450Mbps. This is thrice faster than the usual data speeding with using one carrier.

Teaming up with industry’s frontrunner Korean operators, SAMSUNG Electronics showcased a network, which will make use of two carriers, each having 20MHz bandwidth. This network will be commercially-readied and have at most 300Mbps of data speed. The company is convinced that the improved data speed will provide users with better mobile experience.

The company also showcased SAMSUNG’s Carrier Aggregation solution, the Smart CA. SAMSUNG already launched the Carrier Aggregation in the Korean market and so far, there seems to be problem between primary and secondary frequencies compatibility, which resulted in the users not fully enjoying CA’s benefits. And SAMSUNG Smart CA is the solution to this problem.

SAMSUNG Smart CA offers the solutions, including stepwise technologies Primary Cell Switching and Best Cell Aggregation. These two technologies will help provide enhancements and improvements in the specific sections which will make the network work better. The former can automatically switch frequency when the current one is weak to a better and more stable frequency. The latter on the other hand is a little more advanced than the Primary Cell Switching. The Best Cell Aggregation use the aggregating bands in order to provide best optimal network and support UE. This will increase the total data of the user devices. And finally, the use of CA in general will enable the network to make use of the large coverage and powerful data off-loading.

In the demonstration at the 2014 Mobile World Congress, SAMSUNG showcased the Carrier Aggregation between the small cell and the macro cell. The macro cell will maintain the network’s coverage while the small cells address the offloading data. This is how the CA will be able to support UE connections seamlessly.

Samsung Electronics Networks Business Vice President & Head of Marketing Group Sam Baker explained Carrier Aggregation more and said, “Carrier Aggregation is one of the most essential and popular solution in today’s mobile network, as the technology could maximize the benefits from LTE using various frequency bands. Samsung has been at the top position for developing this technology. As a result, we achieved the world’s first commercialization of Carrier Aggregation with market leading Korean operators in June 2013, and we are also co-working with global mobile operators for further development of this technology. We believe these early experience and expertise on Carrier Aggregation will help mobile operators to launch the most efficient and powerful LTE network.”
