Setting Description
AP EDCA parameters
AIFS Enter the Arbitration Inter-Frame Spacing (AIFS)
interval that specifies the wait time (in
milliseconds) between data frames. A higher AIFS value means a higher priority for a
queue. Valid values for AIFS are 0 through 8.
The default values are Data 0: 3; Data 1: 7; Data 2: 1; Data 3: 1.
cwMin Enter the minimum contention window (cwMin) value that specifies the upper limit (in
mi
lliseconds) of a range from which the initial random back-off wait time is determined.
Decreasing this value increases the priority of the queue. The value for cwMin needs to be
lower than the value for cwMax. Valid values are 0, 1, 3, 7, 15, 31, 63, 127, 255, 511, and
1023.
The default values are Data 0: 15; Data 1: 15; Data 2: 7; Data 3: 3.
cwMax Enter the maximum contention window (cwMax) value that specifies the upper limit (in
mi
lliseconds) for the doubling of the random back-off value. Decreasing this value
increases the priority of the queue. The value for cwMax needs to be higher than the value
for cwMin. Valid values are 0, 1, 3, 7, 15, 31, 63, 127, 255, 511, and 1023.
The default values are Data 0: 63; Data 1: 1023; Data 2: 15; Data 3: 7.
