The system will automatically calculate the ideal reference value for the Slot Time and ACK
Timeout. The input distance is calculated in units (meters).
ACK Timout : When waiting for the "ACKnowledgment frame" interval is too long to be received,

the ACK will be retransmitted. A higher ACK Timeout will reduce packet loss, but the
transmission efficiency will be poor.
Setting Slot Time and ACK Timeout can strengthen the long-distance
connection. Changing the value can optimize the setting. If the value is too
low, the length transmission will be reduced. If the value is too high, there may
be disconnection.

 TX/RX Stream:
Administrator can select 1 or 2 TX/RX. The default is 2TX/2RX.
This product has a built-in 2x2 (2T2R) antenna for 5Ghz, which has been
matched with the default setting of 2T2R. If there is no special demand, please
keep this default setting .
Channel Bandwidth: The "20/40 and 802.11ac 80" MHz option is usually the best. The other

option is available for special circumstances.
Shout GI: Short Guard Interval is "Enabled" by default to 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.
Aggregation: By default, it's "Enable". Select "Disable" to deactivate Aggregation.

A part of the 802.11n standard (or draft-standard). It allows sending multiple frames per single
access to the medium by combining frames together into one larger frame. It creates the larger
frame by combining smaller frames with the same physical source and destination end
traffic class (i.e. QoS) into one large frame with a common MAC header.
