Parameter description
Parameter
Description
Beacon Interval
Used to set the interval at which this device sends Beacon frames.
Beacon frames are sent at the interval to announce the existence of a wireless
network. Generally, a smaller interval allows wireless clients to connect to this device
sooner, while a larger interval allows the wireless network to transmit data quicker.
Fragment Threshold
Threshold of a fragment.
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.
In case of a high error rate, you can reduce the threshold to enable this device to
resend only the fragments that have not been sent successfully, so as to increase the
frame throughput.
In an environment with little interference, you can increase the threshold to reduce the
number of frames, so as to increase the frame throughput.
RTS Threshold
Frame length threshold for triggering the RTS/CTS mechanism. The unit is byte.
If a frame exceeds this threshold, the RTS/CTS mechanism is triggered to reduce
conflicts.
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 to
reduce conflicts.
The RTS mechanism requires some network bandwidth. Therefore, it is triggered only
when frames exceed this threshold.
DTIM Interval
Countdown before this device transmits broadcast and multicast frames in its cache.
The unit is Beacon interval.
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, this device transmits all cached frames at one
Beacon interval.
RSSI Threshold
It specifies the minimum strength of received signals acceptable to this device. If the
strength of the signals transmitted by a wireless device is weaker than this threshold,
the wireless device cannot connect to this device.
A proper value facilitates wireless devices to connect to the AP with stronger signal in
case of multiple APs exist.
