Rohde & Schwarz and EMITE are proud to announce that the new R&S CMWflexx wideband radio communication tester setup has been successfully used in combination to the EMITE E500 reverberation chamber and a channel emulator to test up to 4CC LTE-A FDD CA with 2×2 MIMO on each carrier and more realistic isotropic urban-macro (UMA) fading profiles. The tests were performed for a leading US carrier.
The R&S CMWflexx is specially designed for testing LTE-A with a high number of component carriers. It is the latest addition to the R&S CMW500 wideband communication tester family. The instrument can be used in all phases of product development and production and supports all common cellular and non-cellular wireless technologies.
EMITE’s unique multicavity mode-stirred and source-stirred reverberation chamber solutions (MSRC) provide a variety of fading scenarios at a fraction of the cost of alternative anechoic-chamber-based test solutions. Along with conventional uniform, isotropic Rayleigh and more complex SCME-based fading profiles for MIMO OTA testing, the EMITE solutions are the only ones that also offer other standardized fading profiles using the patented Sample Selection technique, something unheard of in the wireless arena until now.
“We are extremely happy to be the first to integrate the R&S CMWflexx in a MIMO OTA test system for up to 4CC LTE-A FDD carrier aggregation (CA) MIMO OTA with 2×2 MIMO on each carrier component and more realistic UMA fading for all carrier components. This again confirms the leading role of EMITE worldwide when it comes to MIMO OTA reverberation chamber-based test systems,” said David Sanchez-Hernandez, CEO and co-founder of EMITE.
