P-660HWP-Dx User’s Guide

WMM (Wi-Fi MultiMedia) QoS (Quality of Service) allows you to prioritize wireless traffic 
according to the delivery requirements of individual services.

WMM is a part of the IEEE 802.11e QoS enhancement to certified Wi-Fi wireless networks.

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.

The following table describes the priorities that you can apply to traffic that the P-660HWP-
Dx sends to the wireless network.

Set

This is the index number of the MAC address.

MAC 

Address

Enter the MAC addresses of the wireless client that are allowed or denied access to 

the P-660HWP-Dx 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.

Table 40   WMM QoS Priorities 

Highest

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.

High

Typically used for video traffic which has some tolerance for jitter but needs to be 

prioritized over other data traffic. 

Mid

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.

Low

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.
