The parameters of HT Physical Mode are described as follows: 
Field Description 
Operation Mode  You may select Mixed Mode or Green Field. The 
default operation mode is Mixed Mode. 
Channel  You may select 20 or 20/40. The default channel  

 
57 
Field Description 
BandWidth bandwidth is 20/40. 
Guard Interval  You may select Long or Auto. The default guard 
interval is Auto. 
MCS  You may select the MCS value from 0 to 32. The 
default MCS is Auto. 
Reverse Direction 
Grant(RDG) You may select Disable or Enable. The default 
RDG setting is Enable. 
Extension 
Channel Select a proper channel in the drop down list. 
When the channel bandwidth is set to be 20/40 
MHz, the extension channel will provide a channel 
that is adjacent to the...

Field Description 
and encapsulates them to be an 802.11 message. In 
this way, PLCP Preamble, PLCP Header, and 
802.11 MAC overhead that are needed to send an 
802.11 message decrease. At the same time, the 
acknowledge frames also decrease, and the 
efficiency for sending message is improved. 
Auto Block ACK  Enable or disable Auto Block ACK. 
In order to insure the security of the data 
transmission, 802.11n protocol requires that if the 
client receives a unicast frame, it should 
immediately...

On this page, you may configure advanced wireless parameters, such as beacon 
interval, data beacon rate, and Tx power. 
 
Note: 
The advanced wireless setting is only for advanced user. For the common user, do 
not change any setting on this page. 
 
  Advanced Wireless

The parameters of Advanced Wireless are described as follows: 
Field Description 
BG Protection 
Mode Yo u  m a y  s e l e c t  On, Off, or Auto. The default BG 
protection mode is Auto. 
Beacon Interval  By default, wireless beacon signal sends data to 
station every other 100 ms. The range is 20~999. 
Data Beacon Rate 
(DTIM)  The default DTIM is 1ms. The range is 1~255. 
Fragment 
Threshold  The default fragment threshold is 2346. The range is 
256~2346. 
RTS Threshold  The default RTS...

Field Description 
network traffic is dense should use shorter 
preambles. 
Short Preamble is mainly applied to the efficiency 
improvement of real- time applications, such as 
streaming video, and Voice-Over-IP telephony. 
Short Slot Enable or disable short slot. 
Tx Burst  Tx Burst can be used to improve the efficiency of 
data transmission. It can make system transmit 
more data during a period of time. 
Pkt_Aggregate Pkt_Aggregate can aggregate multiple data packets 
together for improving the...

 
62    Multicast-to-Unicast Converter 
 
 
Enable or disable Multicast-to-Unicast. After enabling this function, the transmission 
quality of wireless multicast stream can be improved. 
 
  About WMM 
- WMM Access Categories 
At present, WMM defines traffic into 4 access categories. 
 
 
AC_VO: Voice (highest priority) 
AC_VI: Video (high priority) 
AC_BE: Best effort (medium priority) 
AC_BK: Background (low priority) 
802.11 uses DCF (Distributed Coordination Function) scheme of the CSMA/CA 
(Carrier...

chance for all the devices. 
When each priority queue waits for sending packets, it has to wait a fixed time AIFSN 
and a random time CW. They define time values by multiple time slots. For 802.11b, 
its time slot is 20ms. The time slot of 802.11a and 802.11g is 9 ms. CW insures the 
random delay time of DCF, so that the packets collision among the devices with the 
same access category can be avoided. If collision occurs, CW is doubled until it 
exceeds its maximum value. After every successful...

The parameters on this page 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....

Step2 Enable the DLS function on the Advanced Wireless Settings page. 
 
 
Step3 Enable the DLS function of wireless network cards. Enter the MAC address 
of wireless card A on the WMM page of the wireless network card B, and 
then click the Apply button. 
 
 
Step4 If DLS succeeds, you can view the MAC address of wireless card A on the 
WMM page of wireless card B, and vice versa.
