Parameter
Description
It specifies the threshold of a fragment. Unit: 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.
Fragment Threshold
In an environment of 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.
In an environment without interference, you can increase the threshold to reduce the
number of acknowledgement times, so as to increase the frame throughput.
It specifies the frame length threshold for triggering the RTS/CTS mechanism. Unit:
byte.
If a frame exceeds this threshold, the RTS/CTS mechanism is triggered to reduce
conflicts.
RTS Threshold
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 WiFi network to recover from conflicts
quicker. For a WiFi 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.
Coverage-oriented: This mode broadens WiFi coverage of APs, and is usually used
in scenarios deployed with fewer APs, such as offices, warehouses, and hospitals.
Signal Transmission
Capacity-oriented: This mode effectively decreases mutual interference among
APs, and is usually used in scenarios deployed with massive APs, such as
conferences, exhibition halls, banquet halls, stadiums, classrooms of
higher-education institutes, airports and so on.
It specifies the interval for transmitting the Delivery Traffic Indication Message (DTIM)
frame. Unit: Beacon.
DTIM 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, the AP transmits all cached frames after each
beacon frame is transmitted.
Set a minimum strength of received signals acceptable to the AP. If the strength of the
signals transmitted by a wireless device is weaker than this threshold, the wireless
device cannot connect to the AP.
RSSI Threshold
If there are multiple APs, an appropriate RSSI Threshold ensures that wireless devices
can connect to the AP’ WiFi networks with strong signals.
If enabled, devices that support 5 GHz band choose to connect the AP’s 5 GHz WiFi
network first. Otherwise, they randomly connect to 2.4GHz or 5 GHz WiFi network. This
option is available on the 5 GHz configuration page.
Prioritize 5 GHz
The default RSSI threshold to enable this function is -80 dBm. You can adjust the
