Testing the 2.4, 5, and 6 GHz Bands in IEEE 802.11ax
Nov. 18, 2022
Designing Wi-Fi 6E WLAN products requires simultaneously assuring 6 GHz performance in addition to the existing 2.4 and 5 GHz bands.
The IEEE 802.11 WLAN (Wi-Fi®) standards up to the 802.11ac version define two usable frequency bands of 2.4 GHz and 5 GHz. The 802.11ax revision released in 2021 added a 6 GHz band, increasing the number of usable bands to three. However, with 6 GHz band devices covering the 2.4, 5, and 6 GHz bands while also making efficient use of current designs, it is not easy to confirm the required performance. Learn how to assure the required performance for each band.
This article describes the advantages of open-loop sensors over closed-loop current sensors. Examples of LEM and Honeywell open-loop sensors are described.
