    Using 802.11 Radio

 

Global settings include radio and security settings that apply to all profiles and settings 
that apply to SCU itself. 

 

 

Roam Trigger 

When the moving average RSSI from the current AP is weaker than Roam 

Trigger, radio does a roam scan where it  probes  for  an  AP  with  a  signal 

that is at least Roam Delta dBm stronger — 

 

Value: -50, -55, -60, -65, -70, -75, -80, -85, -90 

 

Default: -70 dBm 

Roam Delta 

When Roam Trigger is met, a second AP’s signal strength (RSSI) must be 

Roam Delta dBm stronger than the moving average RSSI for the current 

AP before radio will attempt to roam to the second AP — 

 

Value: 5, 10, 15, 20, 25, 30, 35 

 

Default: 10 dBm 

Roam Period 

After association or roam scan (with no roam), radio will collect RSSI scan 
data from Roam Period seconds before considering roaming — 

 

Value: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 

 

Default: 10 (seconds)
