WMM stands for
Wi-Fi
Multi
media. It is a standard created
to define quality of service (
QoS) in Wi-Fi networks. It
is a precursor to the upcoming IEEE
802.11e WLAN QoS draft standard, which is
meant to improve audio, video and voice applications transmitted over
Wi-Fi. 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.
