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.
9
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".
9
Txop : 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.
9
ACM : 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.
