Munich, Germany. Rohde & Schwarz and Prisma Telecom Testing have successfully completed verification of LTE FDD five-component carrier (5CC) aggregation in the downlink, including 4×4 MIMO and 256QAM on each carrier. This combination allows data transfer rates up to 2 Gb/s. Rohde & Schwarz presented this test setup to the public for the first time at Mobile World Congress in Barcelona.
The solution consists of an R&S CMWflexx setup and a Prisma UeSIM multiterminal simulator. The R&S CMW500 generates the five component carriers with 20-MHz bandwidth and 4×4 MIMO each using the 3GPP Rel. 12 256QAM modulation. The entire setup is able to provide a downlink data rate of close to 2 Gb/s. The Prisma UeSIM terminates the traffic.
With this successful 5CC 4×4 MIMO verification, Rohde & Schwarz and Prisma Telecom Testing have achieved another milestone in the commercial evolution of LTE-Advanced. The R&S CMW500, in its R&S CMWflexx configuration, and the Prisma UeSIM are the first test platforms to offer a combined downlink carrier aggregation solution for up to five 4×4 MIMO carriers and up to 2 Gb/s throughput, the companies said.
