5.5.2 Station EDCA Parameters
Station EDCA parameters affect traffic flowing from the client station to the EAP device.

Queue
：
Queue displays the transmission queue. By default, the priority
from high to low is Data 0, Data 1, Data 2, and Data 3. The priority
may be changed if you reset the EDCA parameters.
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)—High 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 example).
Arbitration Inter-
Frame Space
：
A wait time for data frames. The wait time is measured in slots. Valid
values for Arbitration Inter-Frame Space are from 0 to 15.
Minimum
Contention
Window
：
A list to the algorithm that determines the initial random backoff
wait time (window) for retry of a transmission. This value can not be
higher than the value for the Maximum Contention Window.
Maximum
Contention
Window
：
The upper limit (in milliseconds) for the doubling of the random
backoff value. This doubling continues until either the data frame is
sent or the Maximum Contention Window size is reached.
This value must be higher than the value for the Minimum
Contention Window.
