Users of Bluetest reverberation test systems can now benefit from the CMX500 5G NR radio communication tester from Rohde & Schwarz for 5G FR1 MIMO OTReverberation chambers from Bluetest in combination with the CMX500 5G NR communication tester from Rohde & Schwarz now enable developers and manufacturers of 5G components and devices to perform MIMO stress testing under realistic conditions with high data rates.

Bluetest, based in Gothenburg, Sweden, specializes in reverberation chambers such as the RTS65 for efficient OTA performance evaluation of the device under test (DUT). Unlike anechoic test chambers, reverberation chambers reflect an RF signal inside the chamber to the greatest possible extent to create a Rayleigh faded multipath RF environment similar to real world indoor and city conditions. The setup is run by the Bluetest Flow software, an integrated test environment for complex wireless systems. It features characteristics such as an integrated result database, comprehensive customization options and a full-fledged scientific computing environment, and supports legacy as well as the latest wireless standards such as 5G NR.

With the CMX500 integrated in the Bluetest Flow control software, the system provides a stable and reliable environment for measuring throughput as well as receiver sensitivity and output power on multicarrier devices with up to 4x4 MIMO.

The CMX500 emulates the network in the test setup. It is a future-proof system for 5G NR testing, allowing both non-standalone and standalone testing in FR1 and FR2. Featuring a modular design, the CMX500 adds 5G capabilities to LTE based legacy solutions such as the well-established CMW500 wideband radio communication tester or the CMWflexx platform.
