5.5.4 When Band Mode select in 802.11a/n mixed mode , the HT(High Throughput)
Physical Mode and 11n Configuration settings should be shown-up immediately.
5.5.4.1 Operating Mode : By default, it's Mixed Mode.
z Mixed Mode : In this mode packets are transmitted with a preamble
compatible with the legacy 802.11a/g, 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.
z Green Field : In this mode high throughput packets are transmitted without a
legacy compatible part.
5.5.4.2 Channel Bandwidth : The " Auto ” MHz option is usually best. The other
option is available for special circumstances.
5.5.4.3 Guard Interval : 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.
5.5.4.4 MCS : 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.
5.5.4.5 MPDU Enable : Check Enable button to activate this function, and Disable
to deactivate.
5.5.4.6 A-MPDU : A-MPDU (Aggregated Mac Protocol Data Unit) allows the
transmissions of multiple Ethernet frames to a single location as burst of up to
64kbytes This is performed on the hardware itself. Select “Manual” to set
“MPDU Density”
5.5.4.7 MPDU Density : Minimum separation of MPDUs in an A-MPDU.
