Bluetest and Rohde & Schwarz extend their long-established collaboration and have integrated the Wi-Fi 7 test functionality of the R&S CMX500 one-box signaling tester into the Bluetest Flow control software. Now, developers and manufacturers of next-generation WLAN technology can use the Bluetest reverberation test systems (RTS) to perform MIMO stress testing of IEEE 802.11be stations as well as access points under realistic conditions.
Bluetest specializes in reverberation chambers, such the RTS65, which are made to effectively evaluate wireless devices’ performance over-the-air.
Unlike anechoic test chambers, reverberation chambers create a Rayleigh faded multipath RF environment by reflecting an RF signal widely inside the chamber. This setting is perfect for testing the radio and antenna performance of contemporary multi-antenna (MIMO) and multi-carrier devices used in WLAN, 4G, and 5G because it closely resembles actual indoor and urban situations.
The Bluetest Flow control software, an integrated test environment for sophisticated wireless technologies, is used to handle the setup. WLAN developers using the R&S CMX500 can now use Bluetest’s reverberation chamber technology in the creation of their sophisticated WLAN stations and access points by incorporating the Wi-Fi 7 test feature of the R&S CMX500 one-box signaling tester into the Bluetest Flow program.
Wi-Fi 7 (IEEE 802.11be) can handle tens of gigabits of data per second with minimal delay because it is designed for very high data throughput.
It meets the growing need for augmented reality, virtual reality, and streaming ultra-high quality videos. Increased channel bandwidth of 320 MHz, up to 16 spatial streams, 4096 QAM modulation, and multi-link operation (MLO) are the main elements that enable better performance.
Measurements of the antennas and the properties of the RF transmitter and receiver must be made in signaling mode under real-world situations while WLAN devices are being developed.
A test environment that offers numerous RF chains is essential because MLO is a core feature of Wi-Fi 7. Rohde & Schwarz’s R&S CMX500 one-box tester is a multi-technology, multi-channel signaling tester with built-in Wi-Fi 7 test features. It is a flexible solution for a wide range of Wi-Fi 7-specific testing because to its embedded IP test capabilities, support for numerous radio technologies, and flexibility.
Key Comments
Christoph Pointner, Senior Vice President of Mobile Radio Testers at Rohde & Schwarz, said: “Our collaboration with Bluetest has resulted in a unique synergy between our CMX500 one-box tester and their RTS technology. This long-established partnership has enabled us to push the boundaries of WLAN testing, providing a real-world environment that is integral to the development of cutting-edge wireless solutions.”
Kjell Olovsson, Bluetest CEO, said: “Teaming up with Rohde & Schwarz and integrating their CMX500 one-box tester into our Flow software broadens our WLAN testing capabilities. Now we are able to offer an unprecedented testing environment for the latest Wi-Fi 7 devices, reflecting our commitment to supporting the evolution of wireless communication.”
