80211eWMM

80211eWMM refers to Wi-Fi Multimedia, an amendment to the IEEE 802.11 standard that enhances quality of service (QoS) for wireless networks. It aims to provide better performance for delay-sensitive applications like voice and video streaming over Wi-Fi. WMM achieves this by prioritizing different types of traffic into four access categories: Voice, Video, Best Effort, and Background. Each category is assigned a different level of priority, allowing for more efficient use of wireless bandwidth and reduced latency. This prioritization is implemented through enhanced medium access control mechanisms, including contention-free periods and parameterized traffic specifications. WMM is a mandatory feature for Wi-Fi 4 (802.11n) and subsequent Wi-Fi certifications, ensuring a baseline level of QoS support across a wide range of wireless devices. It plays a crucial role in making Wi-Fi suitable for applications that require consistent and predictable performance, thereby improving the user experience for multimedia content.
