Configure QoS for Profile Groups

Quality of Service (QoS) works by default. Change QoS only if there is a reason, such as 
device vendor specifications that require you to use different settings.

Using QoS Wi-Fi MultiMedia (WMM) ensures that the applications that require better 
throughput and performance are provided special queues with higher priority. For example, 
video and audio applications are given higher priority over applications such as FTP. WMM 
defines the following four queues in decreasing order of priority:

Voice. The highest priority queue with minimum delay, which makes it ideal for 

applications such as voice over IP (VoIP) and streaming media.

Video. The second highest priority queue with low delay is given to this queue. Video 

applications are routed to this queue.

Best Effort. The medium priority queue with medium delay is given to this queue. Most 

standard IP applications use this queue.

Background. Low priority queue with high throughput. Applications, such as FTP, that 

are not time-sensitive but require high throughput can use this queue.

QoS prioritization and coordination of wireless medium access is on. QoS settings on the 
access point control downstream traffic, flowing from the access point to the client station (AP 
Enhanced Distributed Channel Access [EDCA] parameters) and the upstream traffic flowing 
from the client station to the access point (Station EDCA parameters).
