Setting Description
AIFS Specify a wait time (in milliseconds) for data frames. Valid values for arbitration
inter-frame space (AIFS) are 1 through 255.
The following are the default values for
the AP EDCA parameters:
• Data 0 (Best Effort). 3
• Data 1 (Background). 7
• Data 2 (Video). 1
• Data 3 (Voice). 1
The following are the default values for
the Station EDCA parameters:
• Data 0 (Best Effort). 3
• Data 1 (Background). 7
• Data 2 (Video). 2
• Data 3 (Voice). 2
CwMin Specify an upper limit (in milliseconds) of a range from which the initial random
backoff wait time is determined.
Valid values for this field are 1, 3, 7, 15, 31, 63, 127, 255, 511, or 1023. The value
for the minimum contention window (CwMin) must be lower than the value for the
maximum contention window (CwMax).
The following are the default values for
the AP EDCA parameters:
• Data 0 (Best Effort). 15
• Data 1 (Background). 15
• Data 2 (Video). 7
• Data 3 (Voice). 3
The following are the default values for
the Station EDCA parameters:
• Data 0 (Best Effort). 15
• Data 1 (Background). 15
• Data 2 (Video). 7
• Data 3 (Voice)
. 3
CwMax Specify an upper limit (in milliseconds) for the doubling of the random backoff value.
Valid values for this field are 1, 3, 7, 15, 31, 63, 127, 255, 511, or 1023. The value
for the maximum contention window (CwMax) must be higher than the value for
minimum contention window (CwMin).
The following are the default values for
the AP EDCA parameters:
• Data 0 (Best Effort). 63
• Data 1 (Background). 1023
• Data 2 (Video). 15
• Data 3 (Voice). 7
The following are the default values for
the Station EDCA parameters:
• Data 0 (Best Effort). 1023
• Data 1 (Background). 1023
• Data 2 (Video). 15
• Data 3 (Voice). 7
Max Burst
Note: AP EDCA
parameters only
Specify (in milliseconds) the maximum burst length allowed for packet bursts on the
WiFi network.
A packet burst is a collection of multiple frames transmitted without header
information. Valid values for maximum burst length are 0 through 8192. The
maximum burst length applies only to AP EDCA parameters.
The following are the default values for the AP EDCA parameters:
• Data 0 (Best Effort). 0
• Data 1 (Background). 0
• Data 2 (Video). 3008
• Data 3 (Voice). 1504
