6.3  RF optimization 
The RF Optimization page allows you to modify the radio parameters to optimize performance. 
To access the page, choose Wireless > RF Optimization. 
 
You are recommended to retain the default settings if without the professional guidance to prevent 
degrading wireless performance of the AP. 
 
Parameter description 
Parameter  Description 
Beacon Interval 
It is used to set the interval at which this device sends Beacon frames. 
The Beacon frame is transmitted at the specified interval to announce the presence of 
a wireless network. Generally, a smaller interval enables wireless devices to connect to 
the AP more quickly, while a larger interval ensures higher data transmission speed for 
the AP. 
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. 
Prioritize 5 GHz 
If this function is enabled, dual band wireless devices prefer the 5 GHz WiFi network of 
the AP to connect when the 5 GHz signal strength transmitted by devices is stronger 
than the Prioritize 5 GHz Threshold. 
Prioritize 5 GHz 
Threshold 
With Prioritize 5 GHz function enabled, if the strength of the signals transmitted by a 
wireless device is stronger than this threshold, the wireless device connects to the 5 
GHz WiFi network. Otherwise, it connects to the 2.4 GHz WiFi network.
