13. What is WMM?
Wi-Fi Multimedia (WMM), a group of features for wireless networks that improve the
user experience for audio, video and voice applications. WMM is based on a subset of
the IEEE 802.11e WLAN QoS draft standard. WMM adds prioritized capabilities to
Wi-Fi networks and optimizes their performance when multiple concurring
applications, each with different latency and throughput requirements, compete for
network resources. By using WMM, end-user satisfaction is maintained in a wider
variety of environments and traffic conditions. WMM makes it possible for home
network users and enterprise network managers to decide which data streams are
most important and assign them a higher traffic priority.
14. What is WMM Power Save?
WMM Power Save is a set of features for Wi-Fi networks that increase the efficiency
and flexibility of data transmission in order to conserve power. WMM Power Save has
been optimized for mobile devices running latency-sensitive applications such as
voice, audio, or video, but can benefit any Wi-Fi device. WMM Power Save uses
mechanisms included in the IEEE 802.11e standard and is an enhancement of IEEE
802.11 legacy power save. With WMM Power Save, the same amount of data can be
transmitted in a shorter time while allowing the Wi-Fi device to remain longer in a
low-power “dozing” state.
