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.
The 3CC 4×4 MIMO verification marks an 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.
