What is unequal modulation (UEQM) in Wi-Fi 8?
Unequal modulation (UEQM) in Wi‑Fi 8 lets a device use different modulation levels on different spatial streams in the same MIMO connection. Instead of forcing every stream to use the same scheme, the access point can push higher-order modulation on stronger, cleaner streams and fall back to more robust, lower-order modulation on weaker ones.
Earlier Wi‑Fi generations treated all MIMO streams as if they had the same signal quality. UEQM removes that constraint and matches each stream’s modulation to its real channel conditions. This aims to improve total throughput and reliability, especially in environments where some paths are strong and others are noisy or partially blocked.
