Rohde & Schwarz: test solutions for Broadcom 802.11ax Wi-Fi devices

Rohde & Schwarz announced the availability of test solutions for the Broadcom Max Wi-Fi chipset portfolio, the industry’s first complete ecosystem of 802.11ax Wi-Fi devices. In collaboration with Broadcom Limited, Rohde & Schwarz has successfully verified its R&S CMW test platform for the IEEE 802.11ax ecosystem, enabling wireless OEMs and ODMs to use Broadcom Max Wi-Fi chipsets for R&D, quality control, and production prototyping.

Next generation Wi-Fi, based on the IEEE 802.11ax standard, offers speed, capacity, coverage and battery-life improvements in congested environments. It uses technologies such as uplink/downlink orthogonal frequency division multiplexing access (UL/DL OFDMA), multi-user multiple input multiple output (MU-MIMO) and target wake time. These technologies pose challenges for test and measurement equipment. The T&M instruments from Rohde & Schwarz have been qualified for characterizing Broadcom Max Wi-Fi chipsets, both at the RF level for tests such as error vector magnitude, timing measurements and spectrum emission compliance, and at the protocol level for testing features such as multi-user scheduling, application services and network management. Through the Broadcom manufacturing test license program, Rohde & Schwarz is able to develop software for Broadcom Max Wi-Fi chipsets and provide full 802.11ax test solutions to OEMs and ODMs.

The R&S FSW signal and spectrum analyzer and R&S SMW200A vector signal generator allow EVM tests well below –50 dB, providing the industry’s best performance for R&D testing. The R&S CMW270 wireless connectivity tester is another instrument licensed for Max Wi-Fi testing based on its real WLAN network emulation for IEEE 802.11a/b/g/n/ac/ax. The tester can verify and debug devices from the physical to the application layer within the OSI model.

In addition, the R&S CMW100 communications manufacturing test set is recognized by Broadcom as the market-leading production tester. It provides multi-standard and multi-DUT capabilities for production environments, including test coverage, speed, efficiency and yield.

At this year’s Mobile World Congress, Rohde & Schwarz will showcase a production-ready solution featuring the R&S CMW100 and the Broadcom Max Wi-Fi device.
