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.
