3. In the AP EDCA Parameters section, configure the AP EDCA ((Enhanced Distributed
Channel Access) parameters. AP EDCA parameters affect traffic flowing from the EAP
device to the client station. The following table detailedly explains these parameters.
The following table detailedly explains these parameters:

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. Timesensitive
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).
A wait time for data frames. The wait time is measured in slots. Valid
values are from 0 to 15.
A list to the algorithm that determines the initial random backoff wait
time (window) for retry of a transmission.
This value cannot be higher than the value of 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 of Minimum Contention
Window.
