HT Mode
Mixed Mode: In this mode packets are transmitted with a preamble compatible with the legacy
802.11g/n, the rest of the packet has a new format. In this mode the receiver shall be able to
decode both the Mixed Mode packets and legacy packets.
Green Field: In this mode high throughput packets are transmitted without a legacy compatible
part.
Channel Bandwidth
Set channel width of wireless radio.
20 Channel Width = 20 MHz
20/40 Channel Width = 20/40 MHz (additional channel provides better performance)
Guard Interval
Support Short/Long GI, the purpose of the guard interval is to introduce immunity to
propagation delays, echoes and reflections, to which digital data is normally very sensitive.
Long
Auto
Using “Auto” option can increase throughput. However, it can also increase error rate in some
installations, due to increased sensitivity to radio-frequency reflections. Select the option that works
best for your installation.
MCS
Fix MCS rate for HT rate. (Auto, 0~32)
The Modulation and Coding Scheme (MCS) is a value that determines the modulation, coding
and number of spatial channels.
This parameter represents transmission rate. By default (Auto) the fastest possible transmission rate
will be selected. You have the option of selecting the speed if necessary.
4.2.5 QoS
WMM (Wireless Multi-Media)
use this feature allows wireless devices to take advantage of the wireless environment over other wireless
devices.
WMM Power Saving
An option that allows wireless clients such as notebooks or Laptops to save battery life by sending less
transmission during idle times. Add a check mark to enable this option.
PS Mode
Used for specific application when using WMM Power Saving mode is enabled, use this feature to help with
Quality of Service (QoS) settings; these settings are polled by the priority given to the option in this section.
AC_BE= Best Effort
AC_BK= Background
AC_VI= Video signal
AC_VO=Voice signal
The options allow users to select which Access Category is needed to turn on while the power saving mode
is enabled.
