Wi-Fi Multimedia (WMM) is a Wi-Fi Alliance
interoperability certification based on the
IEEE 802.11e standard, which provides
Quality of Service (QoS) features to IEE 802.11 networks. WMM prioritizes
traffic according to four categories: background, best effort, video and voice.
Configuring WMM consists of adjusting parameters on queues for different
categories of wireless traffic. Traffic is sent to the following queues:
High throughput, non time sensitive bulk
data e.g. FTP
Traditional IP data, medium throughput and
delay.
Time sensitive video data with minimum
time delay.
Time sensitive data such as VoIP and
streaming media with minimum time delay.
Queues automatically provide minimum transmission delays for video, voice,
multimedia and critical applications. The values can further be adjusted
manually:
