Anritsu recently added a new option to extend the functions of its MT8862A wireless connectivity test set by supporting evaluation of IEEE 802.11ax 6 GHz band WLAN TRX characteristics.
Following FCC approval in April 2020 for unlicenced use of the 6 GHz operation band as the first new WLAN frequency band in almost 20 years, countries worldwide are starting device testing and deployment. The IEEE 802.11ax WLAN standard regulates this 6 GHz band and the Wi-Fi Alliance is starting its Wi-Fi 6E certification programme for IEEE 802.11ax 6 GHz devices.
The MT8862A is designed to evaluate RF TRX performance of IEEE 802.11a/b/g/n/ac/ax WLAN devices. Additionally, as well as implementing all-in-one 2,4, 5 and 6 GHz band RF TRX measurements, the MT8862A also supports performance evaluations defined by IEEE 802.11 standards and over-the-air (OTA) performance tests defined by both CTIA and the Wi-Fi Alliance.
By using this option, the MT8862A can evaluate the RF characteristics of IEEE 802.11ax 6 GHz devices using either the Network Mode or Direct Mode. In addition to shorter evaluation time using the Direct Mode, the Network Mode facilitates evaluation under actual operation conditions using signalling messages.
While developing this 6 GHz band option, Anritsu also added support for 160 MHz wide channels. Since the 6 GHz band covers a 1200 MHz wide operation band, use of 160 MHz wide channels becomes practical, which is expected to facilitate streaming of higher-definition video and larger-capacity data than previously possible.
