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 IEEE 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:
Background
Low Priority
High throughput, non time sensitive bulk data e.g. FTP
Best Effort
Medium
Priority
Traditional IP data, medium throughput and delay.
Video
High Priority
Time sensitive video data with minimum time delay.
Voice
High Priority
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:
