Bluetest and Rohde & Schwarz collaborate to supply over-the-air testing of next-generation WLAN gadgets

Bluetest and Rohde & Schwarz lengthen their long-established collaboration and have built-in the Wi-Fi 7 check performance of the R&S CMX500 one-box signaling tester into the Bluetest Stream management software program. Now, builders and producers of next-generation WLAN expertise can use the Bluetest reverberation check methods (RTS) to carry out MIMO stress testing of IEEE 802.11be stations in addition to entry factors underneath sensible situations.

Bluetest focuses on reverberation chambers, such because the RTS65, that are designed for environment friendly over-the-air efficiency analysis of wi-fi gadgets. In distinction to anechoic check chambers, reverberation chambers extensively replicate an RF sign contained in the chamber, making a Rayleigh pale multipath RF atmosphere. This atmosphere intently mirrors real-world indoor and metropolis situations, making it best for evaluating the antenna and radio efficiency of contemporary multi-antenna (MIMO) and multi-carrier gadgets as utilized in WLAN, 4G, and 5G.

The setup is operated utilizing the Bluetest Stream management software program, an built-in check atmosphere for advanced wi-fi options. By integrating the Wi-Fi 7 check performance of the R&S CMX500 one-box signaling tester into the Bluetest Stream software program, WLAN builders using the R&S CMX500 can now leverage Bluetest’s reverberation chamber expertise within the growth of their superior WLAN stations and entry factors.

Wi-Fi 7 (IEEE 802.11be) is engineered for terribly excessive knowledge throughput and able to dealing with tens of gigabits of knowledge per second with low latency. It caters to the growing demand for ultra-high-definition video streaming, digital actuality, and augmented actuality functions. The important thing elements facilitating increased throughput embrace an elevated channel bandwidth of 320 MHz, as much as 16 spatial streams, 4096 QAM modulation, and multi-link operation (MLO).

In the course of the growth of WLAN gadgets, measurements of the antennas in addition to RF transmitter and receiver traits have to be carried out underneath real-world situations in signaling mode. With MLO being a key function in Wi-Fi 7, a check atmosphere that gives a number of RF chains is essential. The R&S CMX500 one-box tester from Rohde & Schwarz, that includes built-in Wi-Fi 7 check performance, is a multi-technology multi-channel signaling tester. Its flexibility, help for a number of radio applied sciences, and embedded IP check capabilities make it a flexible resolution for a broad vary of Wi-Fi 7-specific assessments.

Christoph Pointner, Senior Vice President of Cell Radio Testers at Rohde & Schwarz, mentioned: “Our collaboration with Bluetest has resulted in a novel synergy between our CMX500 one-box tester and their RTS expertise. This long-established partnership has enabled us to push the boundaries of WLAN testing, offering a real-world atmosphere that’s integral to the event of cutting-edge wi-fi options.”

Kjell Olovsson, Bluetest CEO, mentioned: “Teaming up with Rohde & Schwarz and integrating their CMX500 one-box tester into our Stream software program broadens our WLAN testing capabilities. Now we’re in a position to provide an unprecedented testing atmosphere for the newest Wi-Fi 7 gadgets, reflecting our dedication to supporting the evolution of wi-fi communication.”
