Samsung to unveil ‘3Band CA’

Samsung Electronics will showcase its latest developments in Carrier Aggregation (CA)- ‘3Band CA’ at Mobile World Congress 2014.

The networks which are powered by Samsung’s advanced CA technologies will verify significant mobile data speed enhancements, improved cell edge performance, large coverage with powerful data off-loading capability and a better way of handling Heterogeneous Network (HetNet).

‘3Band CA’ aggregates triple carriers with 20 MHz bandwidth each. The demonstration will show total data throughput of ‘3Band CA’ peaking up to 450 Mbps, 3 times faster data speed than using one carrier with 20 MHz bandwidth. By cooperating with leading Korean operators, Samsung will also demonstrate commercially readied network supporting maximum 300 Mbps data speed by aggregating of the two carriers with 20 MHz bandwidth respectively.

Samsung also plans to show a demonstration on ‘Smart CA’, company’s a differentiated solution for Carrier Aggregation. With its early commercial experience of CA in Korean market, Samsung has witnessed considerable coverage mismatches between the primary and the secondary frequencies, and it hinders UE enjoying full benefits of CA.

To deal with this problem, Samsung’s Smart CA provides stepwise technologies, which enables network performance improvements in cell edge areas and enhances user fairness in the network. The technologies are called ‘Primary Cell Switching’ and ‘Best Cell Aggregation’. When the primary cell is in weak signal condition, Primary Cell Switching technology automatically switches the frequency that UE is connecting, to another frequency which is in better status.

In addition, Samsung will also suggest innovative use case of CA which enables network to take benefits of both large coverage and powerful data off-loading. By using high frequency bands for data off-loading and low band frequencies for maintaining fundamental connection between UE and network, mobile operators can utilize their network in the most effective and efficient way.

Furthermore, Samsung will show CA between macro cell and small cell. In this showcase, Samsung shows coverage of network maintained by a macro cell while data offloading is addressed by small cells. Building on this, Samsung supports seamless connections for UE without handovers in the macro cell site.

“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,” said Sam Baker, vice president & head of Marketing Group at Networks Business, Samsung Electronics.

“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,” added Baker.
