802.11g WDS network. HTMIX is for 802.11 g/n WDS
network. Greenfield is for pure 802.11n WDS network.
AP MAC Address
This device connects 4 WDS devices. Enter the MAC
Address in the field to connect.
HT Physical Mode—only configurable in 11 b/g/n mixed or 11n only mode.

Description
Operating Mode
Default: Mixed (Mixed, Green Field).
Mixed mode
: In this mode the device transmits the packets
with preamble compatible legacy (802.11g), 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.
Channel Bandwidth
Click the radio button to choose between 20 MHz or
20/40MHz. This option affects the Phy data rate of radio.
Please refer to the table below
Guard Interval
The 11n device inserts the Guard Interval into the signal.
You can choose the interval between “Long” and “Auto”.
This option affects the Phy data rate of radio. Please refer
to the table below.
MCS
It is Modulation Coding Scheme. The available options are
“Auto, 0, 1, …, 32”. It changes the modulation of this device
and effect the maximum Phy data rate. We recommend
“Auto” setting. For the details, please refer to the table
below.
Reverse Direction
Grant (RDG)
Enable this function to provide more robust data packet
transmission.
Extension Channel
The “20/40” bandwidth mode uses 5 channels. For
example, selecting channel 7 and you can select 3 or 11 for
extension channel. Choose the unused channel for the
extension channel.
Aggregation MSDU
(A-MSDU)
The multiple HT packets can be transmitted with single
ACK reply packet. Enable it to apply this function and
reduce the network congestion.
Auto Block ACK
It is another aggregation technique which prevents sending
ACK in the communication to reduce the network
congestion. If this option is enabled, the device will try to
activate this function when transmitting massive data.
Decline BA Request
Enable this option to decline the Block ACK request
addressed by the other devices.
