2. Specify the settings as described in the following table:
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. V
alid 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
milliseconds) of a range from which the initial random back-of
f 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. V
alid 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
milliseconds) for the doubling of the random back-of
f value. Decreasing this value
increases the priority of the queue. The value for cwMax needs to be higher than the value
for cwMin. V
alid 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.
Max. Burst Enter the maximum burst value that specifies the maximum burst length (in microseconds)
allowed for packet bursts on the wireless network. A packet burst is a collection of multiple
frames transmitted without header information. Decreasing this value increases the priority
of the queue. Valid values for maximum burst length are all multiples of 32 between 0 and
8192, inclusive of 0 and 8192.
The default values are Data 0: 0; Data 1: 0; Data 2: 3008; Data 3: 1504.
