Short Slot
Default: enabled. Reduce the waits after the collision time before
retransmitting. It will increase the throughput.
Tx Burst

other associated AP/Client is available.
Tx Short Preamble
Default: enabled. Only requires disabling it when connecting some old
802.11 b wireless clients.

Default: enabled. This is one of 802.11n technique to increase the data
throughput.

Default: enabled. This function provides Dynamic Frequency Selection
(DFS) and the transmit power control (TPC) to 802.11a MAC.
HT Operation Mode
Default: Mixed (Mixed, Green Field).
Mixed mode
: In this mode the device transmits the packets with
preamble compatible legacy (802.11 a/g), so they can be decoded by
legacy devices. The device receives and decodes both Mixed Mode
packets and legacy packets.
Green Field mode
: the device transmits HT packets without legacy
compatible part. But the device receives and decodes both Green Field
and legacy packets.
HT Guard Interval
Default: 400ns. The 11n device inserts the Guard Interval into the signal.
You can choose the interval between 400ns and 800ns. The available
data rate modes are changed according to the Guard Interval.
