PRISMA Telecom demonstrates Four Component Carrier aggregation for LTE-A


PRISMA Telecom Testing, a supplier of load testing solutions, has successfully completed the world’s first RF tests for LTE FDD four component carrier aggregation (4CC) in the downlink, including 2×2 MIMO.

Carrier Aggregation is a key feature of 4G LTE-Advanced and enables operators to increase download or upload data speeds by adding LTE spectrum blocks (‘component carriers’) together to create a wider aggregated data pipe. The impact for LTE subscribers is enhanced data rate speeds and an improved quality of experience when consuming bandwidth-intensive services such as HD video streaming.

At MWC 2015 in Barcelona, PRISMA will showcase UeSIM in the 4CC test set-up. Equipped with two SDRv3 and one eLSU units terminating the traffic, UeSIM is able to provide a downlink data rate of 600 Mbps – the performance required for tests on 3GPP category 11 (Cat11) devices.

“LTE-A promises a wireless broadband experience that can rival cable broadband in terms of bandwidth and speed. However, absolutely central to delivering on this is component carrier aggregation,” said Sergio Troni, PRISMA Telecom Testing CEO. “By testing, for the very first time in the world, 4CC aggregation, PRISMA has broken new ground for the industry and the LTE-A user experience.”

PRISMA’s unique multi-terminal and multi-standard radio testing solutions accelerate multi-standard end-2-end network verification by generating IP traffic load from real applications running on thousands of concurrent mobiles operating real voice and data sessions.

UeSIM is a complete solution for all LTE/LTE-A testing needs and allows multi-terminal testing over the whole LTE spectrum. The available LTE-Advanced features support Carrier Aggregation in both downlink (DL) and uplink (UL), over any FDD/TDD 3GPP band, Logical Cells configuration, eMBMS and more. Each Software Defined Radio (SDR) unit is able to load up to two 2×2 MIMO carriers. All configurations are fully scalable to test any eNodeB configuration, regardless of size.

At the Mobile World Congress, the 4CC test setup will be showcased by PRISMA at booth 6G41.
