Rohde & Schwarz and Prisma Telecom Testing, a supplier of performance testing solutions, have successfully completed verification of LTE FDD five component carrier (5CC) aggregation in the downlink, including 4x4 MIMO and 256QAM on each carrier. This combination allows data transfer rates up to 2 Gbit/s. Rohde & Schwarz has 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 4x4 MIMO each using the 3GPP Rel. 12 256QAM modulation.
The entire setup is able to provide a downlink data rate of close to 2 Gbit/s. The Prisma UeSIM terminates the traffic.
With this successful 5CC 4x4 MIMO verification, Rohde & Schwarz and Prisma Telecom Testing have achieved another important 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 4x4 MIMO carriers and up to 2 Gbit/s throughput.
