Parameter
Description
Beacon Interval
It specifies the interval for transmitting the Beacon frame. The value range is 20 to 999. The unit
is millisecond.
is millisecond.
The Beacon frame is transmitted at the specified interval to announce the presence of a wireless
network. Generally, a smaller interval enables wireless clients to connect to the AP more
quickly, while a larger interval ensures higher data transmission efficiency.

Fragment
Threshold
Threshold
It specifies the threshold of a fragment. The value range is 256 to 2346. The unit is byte.
Fragmenting is a process that divides a frame into several fragments, which are transmitted and
acknowledged separately. If the size of a frame exceeds this threshold, the frame is fragmented.
acknowledged separately. If the size of a frame exceeds this threshold, the frame is fragmented.
In case of a high error rate, you can reduce the threshold to enable the AP to resend only the
fragments that have not been sent successfully, so as to increase the frame throughput.
fragments that have not been sent successfully, so as to increase the frame throughput.
In an environment without interference, you can increase the threshold to reduce the number of
acknowledgement times, so as to increase the frame throughput.
acknowledgement times, so as to increase the frame throughput.
RTS Threshold
It specifies the frame length threshold for triggering the RTS/CTS mechanism.
If a frame exceeds this threshold, the RTS/CTS mechanism is triggered to reduce conflicts. The
value range is 1 to 2347. The unit is byte.
value range is 1 to 2347. The unit is byte.
Set the RTS threshold based on the actual situation. An excessively small value increases the
RTS frame transmission frequency and bandwidth requirement. A higher RTS frame
transmission frequency enables a wireless network to recover from conflicts quicker. For a
wireless network with high user density, you can reduce this threshold for reducing conflicts.

The RTS mechanism requires some network bandwidth. Therefore, it is triggered only when
frames exceed this threshold.

DTIM Interval
It specifies the interval for transmitting the Delivery Traffic Indication Message (DTIM) frame.
The value range is 1 to 255. The unit is Beacon.
The value range is 1 to 255. The unit is Beacon.
A countdown starts from this value. The AP transmits broadcast and multicast frames in its
cache only when the countdown reaches zero.

For example, if DTIM Interval is set to 1, the AP transmits all cached frames at the Beacon
