Wi-Fi Multimedia (WMM) is a subset of the IEEE 802.11e standard and is essential for enabling Quality of Service (QoS) features in Wi-Fi networks. When WMM is not enabled on an 802.11n WLAN, QoS features are unavailable, which can adversely affect the performance of latency-sensitive applications such as voice over IP (VoIP) and video streaming.گروه آموزشی و پژوهشی سیب

Additionally, certain 802.11n features, like higher data rates and frame aggregation, may not be fully utilized without WMM, leading to suboptimal network performance.
