
AC Type
：
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
。

TxOP Limit
：
Transmission Opportunity is an interval of time when a WME AP has
the right to initiate transmissions onto the wireless medium (WM). This value
specifies (in milliseconds) the Transmission Opportunity (TXOP) for AP; that is, the
interval of time when the WMM AP has the right to initiate transmissions on the
wireless network.
。

ACM bit
：
Admission Control Mandatory, ACM only takes effect on AC_VI and
AC_VO. When you do not click Checkbox, it means that the ACM is controlled by the
connecting AP. If you click Checkbox, it means that the Client is in charge
