transmission behaviour on the access point only, not to that of the client stations.
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.

• For the Guest interface, QoS queue settings apply to the access point load as a whole (both
BSS es together).
• Internal and Guest network traffic is always queued together.
Field Description
Queue
Queues are defined for different types of data transmitted from the access
point-to the client station:
Data 0 (Voice)
Highest priority queue, minimum delay. Time-sensitive data such as VoIP and
streaming media are automatically sent to this queue.
Data 1(Video)
Highest priority queue, minimum delay. Time-sensitive video data is
automatically sent to this queue.
Data 2 (best effort)
Medium priority queue, medium throughput and delay. 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 exam-
ple).
For more information, see “QoS Queues and Parameters to Coordinate Traffic
Flow” on page 144.
AIFS
(Inter-Frame Space)
The Arbitration Inter-Frame Spacing (
AIFS
) specifies a wait time in milliseconds
for data frames.
Valid values for AIFS are 1 through 255.
For more information, see “EDCF Control of Data Frames and Arbitration Inter-
frame Spaces” on page 145.
