Trigger  The TM80 will start 
scanning to search for a 
better AP when the signal 
intensity (RSSI) of current 
connected AP is weaker 
than Trigger. 
It is recommended to set the trigger 
value to the RSSI value of expected 
weakest coverage in the hospital, 
which cannot be lower than -70 dBm. 
The TM80 requires that the network 
deployed in the hospital meet the 
requirement of -65 dBm. 
It is reasonable to set the trigger value 
in the range of -70 to -65.
