As an Example, time-sensitive Voice & Video, and multimedia are given effectively higher
priority for transmission (lower wait times for channel access), while other applications
and traditional IP data which are less time-sensitive but often more data-intensive are
expected to tolerate longer wait times.

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.
