Rohde & Schwarz and Prisma Telecom Testing present world’s first test setup for three component carrier aggregation with 4×4 MIMO

Test and measurement specialist Rohde & Schwarz and Prisma Telecom Testing, a leading supplier of load testing solutions, have successfully completed verification of LTE FDD three component carrier (3CC) aggregation in the downlink, including 4×4 MIMO on each carrier. Rohde & Schwarz will present the test setup to the public for the first time at Mobile World Congress in Barcelona.

The solution consists of three R&S CMW500 wideband radio communication testers, the R&S CMWC controller and the Prisma UeSIM multiterminal simulator. Each R&S CMW500 generates a component carrier with 20 MHz bandwidth and 4×4 MIMO. The entire setup is able to provide a downlink data rate of 900 Mbit/s. The Prisma UeSIM is equipped with two SDRv3 units and one eLSU unit for terminating the traffic.

With this successful 3CC 4×4 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 three 4×4 MIMO carriers, for protocol, RF and data performance verification up to 1 Gbp/s.

At Mobile World Congress, the R&S CMWflexx 3CC 4×4 MIMO test setup will be on display at the Rohde & Schwarz booth C40 in hall 6. At booth G41 in hall 6, Prisma Telecom Testing will showcase a downlink four component carrier aggregation (4CC) test scenario using the 3GPP Rel. 12 256QAM modulation feature. 256QAM enhances the 600 Mbit/s 3GPP Rel-10 (64QAM modulation) throughput to 800 Mbit/s.
