The network signal for a single wireless access point might be limited by its coverage range. 
Therefore, if you want to expand the wireless network in a large exhibition with a quick 
method, you can install multiple access points with enabling the Roaming feature for each 
AP to reach the purpose of expanding wireless signals seamlessly. 
These access points connecting for each other shall be verified by pre-authentication. This 
page allows you to enable the roaming feature and the pre-authentication. 
Available settings are explained as follows:

Roaming Parameters 
When the link rate of wireless station is too low or the signal 
received by the wireless station is too worse, VigorAP 902 will 
automatically detect (based on the link rate and RSSI 
requirement) and cut off the network connection for that wireless 
station to assist it to connect another Wireless AP to get better 
signal. 
Minimum Basic Rate – Check the box to use the drop down list

station is below such value, VigorAP 902 will terminate the 
network connection for that wireless station.

strength indicator) to decide to terminate the network connection 
of wireless station. When the signal strength is below the value 
(dBm) set here, VigorAP 902 will terminate the network 
connection for that wireless station. 
Minimum RSSI - When the signal strength of the wireless 
station is below the value (dBm) set here and adjacent AP (must 
be DrayTek AP and support such feature too) with higher signal 
strength value (defined in the field of With Adjacent AP RSSI 
over) is detected by VigorAP 902, VigorAP 902 will terminate
