The reverberation chambers from Bluetest, together with the Rohde & Schwarz R&S CMX500, now allow developers and manufacturers of 5G components and devices to achieve MIMO stress testing under realistic conditions with high data rates.
Bluetest specialises in reverberation chambers such as the RTS65 for efficient OTA performance evaluation of the DUT. Unlike anechoic test chambers, reverberation chambers reflect an RF signal inside the chamber to the highest possible extent to produce a Rayleigh faded multipath RF environment similar to real-world indoor and city conditions. The setup is controlled by the Bluetest Flow software, an integrated test environment for complex wireless solutions. It offers an integrated result database, comprehensive customisation options and a full-fledged scientific computing environment and supports legacy and the latest wireless standards such as 5G NR.
The device emulates the network in the test setup. It is a future-proof solution for 5G NR testing, enabling non-standalone and standalone testing in FR1 and FR2. Featuring a modular design, the device adds 5G capabilities to LTE based legacy solutions such as the well-established R&S CMW500 wideband radio communication tester or the R&S CMWflexx platform.
Christoph Pointner, senior vice president Mobile Radio Testers at Rohde & Schwarz, says: “We are happy to continue our cooperation with industry-leading partner Bluetest and to provide our valued clients with top-class 5G test solutions. For Rohde & Schwarz, this integration is a welcome addition that enhances our already comprehensive 5G test and measurement portfolio.”
Klas Arvidsson, Bluetest product manager, comments: “The R&S CMX500 and the popular RTS65, or the larger RTS85/RTS95 walk-in chambers, together create a user-friendly, yet powerful, test setup for RF R&D of 5G devices of various sizes including larger IoT equipment.”
