＊＊Attention＊＊
Before enabling WMM function, you have to disabled "Super TX" or " TX Burst" funciton on the advanced settings of wireless network.

Configuration of WMM
There are four kinds of configuration items for WMM.：
AC_BE：Best Effort (high priority)
AC_BK：Background (low priority)
AC_VI：Video (video first)
AC_VO：Voice (voice first)

Configuration of the parameters of WMM
There are two categories of parameters on the left side：
APAifsn, APCwmin, APCwmax, APTxop, APACM are the parameters for configuring AP.
BSSAifsn, BSSCwmin, BSSCwmax, BSSTxop, BSSACM are for configuring Station

BLW-HPMM/HPMM-U/HPMM-G have already provided you the standard configuration of WMM. 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.

ACM：Admission Control Mandatory
ACM only takes effect on AC_VI and AC_VO. When you set the value as 0, it means that the ACM is controlled by the connecting AP. If you set the value as 1, it means that the Client is in charge.

Ackpolicy：Acknowledgement Policy
When the WMM packets be delivered, it will also send a request back. If you set the value as 0, it means that the system do not want to answer the request. If the value is 1, it means that the system will reply the request. If the system does not reply the request, WMM might have better efficiency.

DLS：Direct Link Setup
BLW-HPMM/HPMM-U/HPMM-G support DLS (Direct Link Setup) function. If you have 2 WMM products, all you have to do is to enter the MAC address of one WMM product into another product, and then connect these two products to BLW-HPMM/HPMM-U/HPMM-G, our products can make these two WMM products link together directly.
