4.8 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.

4.8.1 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.

DESCRIPTION
Select a preamble type from the drop-down list menu. Choices are Long, Short or
Dynamic. The default setting is Long. See the section on preamble for more
information.
Select 802.11b Only to allow only IEEE 802.11b compliant WLAN devices to
associate with the Prestige.
Select 802.11g Only to allow only IEEE 802.11g compliant WLAN devices to
associate with the Prestige.
Select Mixed to allow either IEEE802.11b or IEEE802.11g compliant WLAN devices
to associate with the Prestige. The transmission rate of your Prestige might be
reduced.
Select G+ Enhanced checkbox to allow any ZyXEL WLAN devices that support this
feature to associate with the Prestige at higher transmission speeds. This permits the
Prestige to transmit at a higher speed than the 802.11g Only mode.
Click Apply to save your changes back to the Prestige.
Click Reset to reload the previous configuration for this screen.
