2) Set WMM Parameters Click the WMM Configuration button, the following page appears. On this page, you can configure WMM parameters of access point and station.The parameters are described as follows: Field Description Aifsn Aifsn (Arbitrary Inter-Frame Space Number). This parameter influences the delay time of WMM access category. If you use voice or video service, you'd better set this parameter to be smaller in the fields of AC_VI and AC_VO. If it is E-mail or Web service, you should set a bigger value in the fields of AC_BE and AC_BK. Cwmin Cwmin (Mini. Contention Window) also influences the delay time of WMM access category. The difference between AC_VI and AC_VO should be smaller, but the difference between AC_BE and AC_BK should be bigger. Cwmax Cwmax (Max.Contention Window) Txop Txop (Opportunity to Transmit) may optimize the WMM access. Compared to the WMM access that needs a higher priority, such as AC_VI and AC_VO, this value should be bigger. ACM ACM (Admission Control Mandatory) parameter only reacts on AC_VI and AC_VO. If you set this value to be 0, it indicates that AP is in the charge of the access commands. 34

Set WMM Parameters
Click the
WMM Configuration
button, the following page appears.
On this page, you can configure WMM parameters of access point and
station.The parameters are described as follows:
Field
Description
Aifsn
Aifsn (Arbitrary Inter-Frame Space Number). This
parameter influences the delay time of WMM access
category. If you use voice or video service, you’d better set
this parameter to be smaller in the fields of AC_VI and
AC_VO. If it is E-mail or Web service, you should set a
bigger value in the fields of AC_BE and AC_BK.
Cwmin
Cwmin (Mini. Contention Window) also influences the delay
time of WMM access category. The difference between
AC_VI and AC_VO should be smaller, but the difference
between AC_BE and AC_BK should be bigger.
Cwmax
Cwmax (Max.Contention Window)
Txop
Txop (Opportunity to Transmit) may optimize the WMM
access. Compared to the WMM access that needs a higher
priority, such as AC_VI and AC_VO, this value should be
bigger.
ACM
ACM (Admission Control Mandatory) parameter only reacts
on AC_VI and AC_VO. If you set this value to be 0, it
indicates that AP is in the charge of the access commands.
