WMM (Wi-Fi Multimedia) is a subset of the IEEE RFC known as 802.11e. WMM is
designed to support user applications and works with all three 802.11 wireless physical
layer standards - 802.11a, 802.11b and 802.11g. The specification provides basic
prioritization of data packets based on four categories - voice, video, best effort and
background.
WMM Power Save function can extend the battery life of Wi-Fi devices by increasing the
efficiency and flexibility of data transmission. It is an addition to WMM technology that
enables Quality of Service (QoS) functionality in Wi-Fi networks by prioritizing traffic from
different applications.
