Setting Description
AIFS Specify a wait time (in milliseconds) for data frames. Valid values for arbitration
inter-frame space (AIFS) are 1 through 255.
These 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
These 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
backof
f wait time is determined.
V
alid values for this field are 1, 3, 7, 15, 31, 63, 127, 255, 511, or 1023. The value
for the minimum contention window (CwMin) needs to be lower than the value for
the maximum contention window (CwMax).
These 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
These 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) needs to be higher than the value
for minimum contention window (CwMin).
These 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
These 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 wireless network.
A packet burst is a collection of multiple frames transmitted without header
information. V
alid values for maximum burst length are 0.0 through 999.9.
The
maximum burst length applies only to AP EDCA parameters.
These 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
