Rohde & Schwarz, Broadcom Team to Test Wi-Fi 6/6E Chipsets

Dec. 22, 2021
Rohde’s CMP180 radio communication tester has been successfully validated for Broadcom’s Wi-Fi 6E chipsets, enabling OEMs to bring next-generation 6-GHz products to market.

Check out our CES 2022 coverage.

Rohde & Schwarz, in a collaboration with Broadcom, has successfully verified R&S’s new CMP180 wireless device test platform for test of Broadcom’s 6-GHz Wi-Fi 6E chipsets. This means that OEMs and ODMs of wireless equipment planning to integrate Broadcom’s industry-first chipsets have access to a test platform for R&D, quality control, and production prototyping.

The IEEE 802.11ax amendment (Wi-Fi 6/6E), operating in the 2.4-GHz, 5-GHz, and 6-GHz bands, intends to improve WLAN system efficiency, especially the throughput per station in dense signal environments and outdoor environments. With up to 1.2 GHz of Wi-Fi spectrum available for unlicensed use in the 6-GHz band, Wi-Fi 6E can access up to seven 160-MHz channels to support various bandwidth-driven use cases.

These technologies pose challenges for test and measurement equipment. For example, the 1024QAM modulation requires signal generation capabilities which transmit reference signals with very low distortion over a bandwidth of up to 160 MHz and the required analysis bandwidth. The R&S CMP180 has been qualified for characterizing Broadcom’s 6-GHz Wi-Fi chipsets at the RF level for tests such as error vector magnitude (EVM), timing measurements, and spectrum-emission compliance. Rohde & Schwarz also provides a Wireless Manufacturing software for Broadcom 6-GHz Wi-Fi chipsets and service solutions to OEMs and ODMs.

The R&S CMP180 radio communication tester is a future-proof, non-signaling testing solution for wireless devices in research and development, validation, and production. Together with advanced frequency, bandwidth, and RF capabilities, it enables testing of new wireless technologies such as Wi-Fi 6E, Wi-Fi 7, and many more. Additionally, the doubled number of analyzers (2xVSA), generators (2xVSG), and RF ports (2x8) enable simultaneous measurements of technologies and devices in a VSA/VSG single-box tester.

At CES 2022 in Las Vegas from January 5 to January 8, 2022, Rohde & Schwarz (LVCC, West Hall, #4069) will showcase a Wi-Fi 6E test setup featuring the R&S CMP180 and the BCM4389 Wi-Fi 6E device from Broadcom.
