Note:
 For the G
uest interface or VWNs (Virtual APs), QoS queue settings apply to the
access point load as a whole (all BSSs together).
 These settings apply to both radios but the traffic for each radio is queued
independently.
Configuring Quality of Service includes:
 Configuring AP EDCA Parameters
 Enabling/Disabling Wi-Fi Multimedia
 Updating Settings
Configuring AP EDCA Parameters
AP Enhanced Distributed Channel Access (EDCA) Parameters affect traffic flowing from the access
point to the client station. The default values for the AP and station EDCA parameters are those
suggested by the Wi-Fi alliance in the WMM specification. In normal use these values should not need to
be changed. Changing these values will affect the QoS provided.
Field Description
Queue Queues are defined for different types of data transmitted from
AP-to-station:
Data 0 (Voice)
Low latency and guaranteed bandwidth. Time-sensitive data such as
VoIP should be sent to this queue.
Data 1(Video)
Guaranteed bandwidth. Time-sensitive video data and any streams that
have a fixed bandwidth should be sent to this queue.
Data 2 (best effort)
Most traditional IP data is sent to this queue.
Data 3 (Background)
Lowest priority queue, high throughput. Bulk data that requires
maximum throughput and is not time-sensitive is sent to this queue
(FTP data, for example).

Coordinate Traffic Flow
