as guard interval, the AP router will choose short guard
interval (increasing the wireless performance) or long
guard interval for data transmit based on the station
capability.
Aggregation MSDU
Aggregation MSDU can
combine frames with different
sizes.
It is used for improving MAC layer’s performance
for some brand’s clients. The default setting is
Enable.
3.6.6 WMM Configuration
WMM is an abbreviation of Wi-Fi Multimedia. It defines the priority levels for four access
categories derived from 802.1d (prioritization tabs). The categories are designed with specific
types of traffic, voice, video, best effort and low priority data. There are four accessing
categories - AC_BE , AC_BK, AC_VI and AC_VO for WMM.
APSD (automatic power-save delivery) is an enhancement over the power-save mechanisms
supported by Wi-Fi networks. It allows devices to take more time in sleeping state and
consume less power to improve the performance by minimizing transmission latency. Such
function is designed for mobile and cordless phones that support VoIP mostly.
WMM Capable
To apply WMM parameters for wireless data transmission,
please click the
Enable
radio button.
APSD Capable
The default setting is
Disable
.
Aifsn
It controls how long the client waits for each data
transmission. Please specify the value ranging from 1 to 15.
Such parameter will influence the time delay for WMM
accessing categories. For the service of voice or video
image, please set small value for AC_VI and AC_VO
categories For the service of e-mail or web browsing,
please set large value for AC_BE and AC_BK categories.
CWMin/CWMax
CWMin
means contention Window-Min and
CWMax
means contention Window-Max. Please specify the value

Vigor2110 Series User’s Guide
75
ranging from 1 to 15. Be aware that CWMax value must be
greater than CWMin or equals to CWMin value. Both
values will influence the time delay for WMM accessing
categories. The difference between AC_VI and AC_VO
categories must be smaller; however, the difference
between AC_BE and AC_BK categories must be greater.
Txop
It means transmission opportunity. For WMM categories
of AC_VI and AC_VO that need higher priorities in data
transmission, please set greater value for them to get
highest transmission opportunity. Specify the value
ranging from 0 to 65535.
ACM
It is an abbreviation of Admission control Mandatory. It
can restrict stations from using specific category class if it
is checked.
Note:
Vigor2820 provides standard WMM configuration
in the web page. If you want to modify the parameters,
please refer to the Wi-Fi WMM standard specification.
AckPolicy
“
Uncheck” (default value) the box means the AP router
will answer the response request while transmitting WMM
packets through wireless connection. It can assure that the
peer must receive the WMM packets.
“Check” the box means the AP router will not answer any
response request for the transmitting packets. It will have
better performance with lower reliability.
