World’s First Test Setup for Four Component CA at MWC


Milan / Munich – February 23, 2015 – PRISMA Telecom Testing, a leading supplier of load testing solutions, and test and measurement specialist Rohde & Schwarz have successfully completed RF tests for LTE FDD four Component Carrier Aggregation (4CC) in the downlink, including 2×2 MIMO. The two companies will present the test setup to the public for the first time at the Mobile World Congress in Barcelona. The solution consists of two R&S CMW500 wideband radio communication testers, the R&S CMWC controller and PRISMA UeSIM multi-terminal simulator. Each R&S CMW500 generates two component carriers with 20 MHz bandwidth and 2×2 MIMO. The entire setup is able to provide a downlink data rate of 600 Mbps – the performance required for tests on 3GPP category 11 (Cat11) devices. PRISMA’s UeSIM is equipped with two SDRv3 and one eLSU units terminating the traffic.
With this successful 4CC demonstration, PRISMA Telecom Testing and Rohde & Schwarz have achieved an important milestone for the commercial evolution of LTE-Advanced. At the Mobile World Congress, the 4CC test setup will be showcased by PRISMA at booth 6G41, and by Rohde & Schwarz at booth 6C40.

Multi-terminal simulation over 3GPP radio interfaces


MsSIM, 3GSIM and UeSIM are part of the LSU SDR Family designed by PRISMA to test radio interfaces with different standards, using a common hardware and a modular software architecture. LSU SDR hardware and software releases follow closely the evolving 3GPP standards

Reduce LTE complexity using the AirMosaic GUI


To manage more effectively the full range of all possible configurations for all protocol layers (i.e. RF power thresholds, interference, data transfer protocols, servers configurations, etc.), PRISMA has developed a unique Graphical User Interface called AirMosaic

Inter Radio Access Technology Testing


A key requirement for all 3GPP standards is the interoperability between different Radio Access Technologies. PRISMA provides multi-terminal solutions for 2G, 3G and 4G radio standards, fully manageable from a single control point
