WMM Application Functions 

WMM Enable 

If you have other devices on your network that support 
WMM, Select 

Enabled

. Otherwise, keep it disabled. 

APSDCapable 

Automatic Power Save Delivery is a more efficient power 
management method than legacy 802.11 Power Save Polling. 
Most newer 802.11 STAs already support a power 
management mechanism similar to APSD. 

DLSCapable 

Direct Link Setup allows direct STA-to-STA frame transfer 
within a BSS. This is designed for consumer use, where 
STA-to-STA transfer is more commonly used.

WMM Parameter 
Configure 

There are two categories of parameters

APAifsn, 

APCwmin, APCwmax, APTxop, APACM are the parameters 
for configuring AP. 
BSSAifsn, BSSCwmin, BSSCwmax, BSSTxop, BSSACM 
are for configuring Station 

T

AC: 

Access Category

 

AC_BE

Best Effort (high priority) 

AC_BK

Background (low priority) 

AC_VI

Video (video first) 

AC_VO

Voice (voice first) 

If you want to alter any of the parameters above, please refer 
to the instructions of your WMM products. 

 

 

Instructions of the parameters of WMM

 

Aifsn

Arbitrary Inter-Frame Space Number

 

The back-off timing for each access category consists of a 
fixed period called the 

Arbitrary Inter-Frame Space Number

 

followed by a random period called the 

Contention 

Window (CW),

 both specified in multiples of the slot time. 

If the service you are using is VI or VO, the value of the 
parameters of AC_VI or AC_VO should be smaller. If 
the service is E-Mail or Web, the value of the parameters 
of AC_BE or AC_BK should be greater.  

Cwmin

Contention Window-Min.

 

Cwmax

Contention Window-Max.

 

The maximum and the minimum value of Contention 
Window both affect the back-off timing of WMM access 
category. In AC_VI and AC_VO, the difference between 
the maximum and minimum value should be smaller, 
however, in AC_BE and AC_BK the difference between 
the maximum and minimum value should be greater.  

Txop

Transmission Opportunity

 

Txop can optimize the configuration of WMM access. 
Those which need prior WMM access, such as AC_VI 
and AC_VO, need greater value of parameters.
