8.3 Technical Reference
This section provides technical background information about the topics covered in
this chapter.
8.3.1 WMM QoS
WMM (Wi-Fi MultiMedia) QoS (Quality of Service) ensures quality of service in
wireless networks. It controls WLAN transmission priority on packets to be
transmitted over the wireless network.
WMM QoS prioritizes wireless traffic according to the delivery requirements of the
individual and applications. WMM QoS is a part of the IEEE 802.11e QoS
enhancement to certified Wi-Fi wireless networks.
On APs without WMM QoS, all traffic streams are given the same access priority to
the wireless network. If the introduction of another traffic stream creates a data
transmission demand that exceeds the current network capacity, then the new
traffic stream reduces the throughput of the other traffic streams.
The NWA uses WMM QoS to prioritize traffic streams according to the IEEE 802.1q
or DSCP information in each packet’s header. The NWA automatically determines
the priority to use for an individual traffic stream. This prevents reductions in data
transmission for applications that are sensitive to latency and jitter (variations in
delay).

WMM QoS Priorities
PRIORITY LEVEL
DESCRIPTION
voice
(WMM_VOICE)
Typically used for traffic that is especially sensitive to jitter. Use
this priority to reduce latency for improved voice quality.
video
(WMM_VIDEO)
Typically used for traffic which has some tolerance for jitter but
needs to be prioritized over other data traffic.
