AP-51xx Access Point Product Reference Guide
1.2.7 Quality of Service (QoS) Support
The access point QoS implementation provides applications running on different wireless devices a
variety of priority levels to transmit data to and from the access point. Equal data transmission priority
is fine for data traffic from applications such as Web browsers, file transfers or email, but is
inadequate for multimedia applications.
Voice over Internet Protocol (VoIP), video streaming and interactive gaming are highly sensitive to
latency increases and throughput reductions. These forms of higher priority data traffic can
significantly benefit from the access point QoS implementation.The WiFi Multimedia QOS Extensions
(WMM) implementation used by the access point shortens the time between transmitting higher
priority data traffic and is thus desirable for multimedia applications. In addition, U-APSD (WMM
Power Save) is also supported.
WMM defines four access categories—voice, video, best effort and background—to prioritize traffic
for providing enhanced multimedia support.
