Hints for IEEE 802.11be EVM Measurements

This document provides some technical background and guidance on how to optimize the measurement of one of the key performance parameters of WLAN transmitters - the Error Vector Magnitude (EVM).

IEEE 802.11be Extremely High Throughput (EHT), also known as Wi-Fi 7, is the latest amendment of the IEEE 802.11 standard and is still under development. This amendment focuses mainly on improved throughput. To do so, the most notable changes currently implemented are:

► New modulation scheme: 4096-QAM (4K-QAM)

► Larger bandwidth: 320 MHz

► Support for 16x16 MU-MIMO

► Enhanced resource allocation in OFDMA

This places special demands on the measurement equipment.
