AP-5131 Introduction 1-9
1.2.7 Quality of Service (QoS) Support
The AP-5131 QoS implementation provides applications running on different wireless devices a
variety of priority levels to transmit data to and from the AP-5131. 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 AP-5131 QoS implementation.The WiFi Multimedia QOS Extensions
(WMM) implementation used by the AP-5131 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.
For detailed information on configuring QoS support for the AP-5131, see Setting the WLAN Quality
of Service (QoS) Policy on page 5-34.
1.2.8 Industry Leading Data Security
