7.8 WMM QoS

WMM (Wi-Fi MultiMedia) QoS (Quality of Service) ensures quality of service in wireless
networks for multimedia applications.
WMM allows you to prioritize wireless traffic according to the delivery requirements of the
individual and applications.
WMM is a part of the IEEE 802.11e QoS enhancement to certified Wi-Fi wireless networks.

7.8.1 WMM QoS Example

When WMM QoS is not enabled, all traffic streams are given the same access throughput 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.
When WMM QoS is enabled, the streams are prioritized according to the needs of the
application. You can assign different priorities to different applications. This prevents
reductions in data transmission for applications that are sensitive.

7.8.2 WMM QoS Priorities

The following table describes the priorities that you can apply to traffic that the ZyXEL
Device sends to the wireless network.

Mid

DESCRIPTION
This is the index number of the MAC address.
Enter the MAC addresses of the wireless station that are allowed or denied access to
the ZyXEL Device in these address fields. Enter the MAC addresses in a valid MAC
address format, that is, six hexadecimal character pairs, for example,
12:34:56:78:9a:bc.

Typically used for voice traffic or video that is especially sensitive to jitter
(variations in delay). Use the highest priority to reduce latency for improved
voice quality.
Typically used for video traffic which has some tolerance for jitter but needs to
be prioritized over other data traffic.
Typically used for traffic from applications or devices that lack QoS
capabilities. Use mid priority for traffic that is less sensitive to latency, but is
affected by long delays, such as Internet surfing.
This is typically used for non-critical "background" traffic such as bulk
transfers and print jobs that are allowed but that should not affect other
applications and users. Use low priority for applications that do not have strict
latency and throughput requirements.
