：
Queue Data Transmitted
AP to Clients
Priority
Description
AC_BK
Background
Low
High throughput. Bulk data that requires maximum
throughput and is not time-sensitive is sent to this
queue (FTP data, for example).
AC_BE
Best Effort
Medium
Medium throughput and delay. Most traditional IP
data is sent to this queue.
AC_VI
Video
High
Minimum delay. Time-sensitive video data is
automatically sent to this queue.
AC_VO
Voice
High
Time-sensitive data like VoIP and streaming media
are automatically sent to this queue.
CWmin
：
Minimum Contention Window. This parameter is input to the algorithm that determines the
initial random backoff wait time ("window") for retry of a transmission. The value specified
here in the Minimum Contention Window is the upper limit (in milliseconds) of a range from
which the initial random backoff wait time is determined.
。
CWmax
：
Maximum Contention Window. The value specified here in the Maximum Contention
Window is 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. Once the Maximum Contention Window size is reached, retries will
continue until a maximum number of retries allowed is reached. Valid values for the "cwmax"
are 1, 3, 7, 15, 31, 63, 127, 255, 511, or 1024. The value for "cwmax" must be higher than the
value for "cwmin".
。
AIFS
：
The Arbitration Inter-Frame Spacing Number specifies a wait time (in milliseconds) for
data frames
。
