Station EDCA Parameters

Queue

Specifies the four ingress queues:

Data 0 (Voice) - High priority queue, with
minimum delay. The queue is used to
store time-sensitive data, such as VOIP
and streaming media.

Data 1 (Video): High priority queue, with
minimum delay. The queue is used to
store time-sensitive data, such as video
traffic.

Data 2 (best effort): Medium priority
queue, with minimum throughput and
delay. The queue is used to store most
traditional IP data.

Data 3 (Background): Lowest priority
queue, with high throughput. This queue
is used for bulk data that requires
maximum throughput and is not time-
sensitive, such as FTP packets.

AIFS (InterFrame Space)

Specifies the Arbitration Inter-Frame
Spacing (AIFS) value, which controls the
wait time for data frames. The wait time is
measured in slots and has a range of 1 to
15 slots.

cwMin (Minimum
Contention Window)

Specifies a value that an algorithm uses to
determine the initial random backoff wait
time (window) for resending packets
during a period of contention for Unified
Access Point resources.

This value is the upper limit (in
milliseconds) of a range from which the
access point determines the initial random
backoff wait time.
