WMM Parameters
The WMM table includes these parameters:
•
AC_BK : Access Category - Background. Lowest priority. Data with no delay or throughput
requirement, such as bulk data transfers.
•
AC_BE : Access Category - Best Effort. Normal priority, medium delay and throughput.
Data only affected by long delays. Data from applications or devices that lack QoS
capabilities.
•
AC_VI : Access Category - Video. High priority, minimum delay. Time-sensitive data such
as streaming video.
•
AC_VO : Access Category - Voice. Highest priority, minimum delay. Time-sensitive data
such as VoIP (Voice over IP) calls.
•
CWmin : Minimum Contention Window. The initial upper limit of the random backoff wait
time before wireless access can be attempted. The initial wait time is a random value
between zero and the CWMin value. Specify the CWMin value in the range 0-15
microseconds. Note that the CWMin value must be equal or less than CWMax value.
•
CWmax : Maximum Contention Window. The maximum upper limit of the random backoff
wait time before wireless access can be attempted. The contention window is doubled after
each detected collision up to the CWMax value. Specify the CWMax value in the range 0-
15 microseconds. Note that the CWMax must be greater or equal to the CWMin value.
•
AIFSN : Arbitration Inter-Frame Space Number. The minimum amount of wait time before
the next transmission attempt. Specify the AIFSN value in the range 0-15 microseconds.
