At CES 2023, Rohde & Schwarz and Broadcom will show an automated test solution for Broadcom Wi-Fi 7 chipsets, the industry’s first Wi-Fi 7 chipsets optimized for mobile handsets that also support simultaneous dual-band 2x2 IEEE 802.11be-compliant operation.
The IEEE 802.11be amendment covers Wi-Fi 7 operation in the 2.4-, 5-, and 6-GHz bands. The amendment will govern the extremely high WLAN throughput needed for advanced applications on mobile handsets. The advanced 4096QAM modulation scheme, wide WLAN channels of 320 MHz available in the 6-GHz band, and multi-link operation (MLO) are key elements to realize such high throughput in a mobile handset.
IEEE 802.11be poses several challenges to test and measurement equipment. For one thing, the 4096QAM modulation requires signal generation capabilities that transmit reference signals with very low distortion over a bandwidth of up to 320 MHz, in addition to the required analysis bandwidth. For another, applied MIMO and MLO schemes demand high performance and scalable test solutions.
The R&S CMP180 radio communications test platform is qualified to characterize Broadcom Wi-Fi 7 chipsets at the RF level to test error vector magnitude (EVM), timing measurements, and spectrum emission compliance. Rohde & Schwarz WMT software service has a Python-based modular test automation framework that also supports the latest Broadcom Wi-Fi 7 chipsets.
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.
Rohde & Schwarz will present a Wi-Fi 7 test setup with the R&S CMP180 and the Wi-Fi 7 device from Broadcom at CES 2023 in Las Vegas from January 5 to January 8, 2023, in West Hall at booth 6757.
