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 (dBm): -50, -55, -60, -65, -70, -75, -80, -85, -90, Custom 

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 (dBm): 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 (sec): 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, Custom 

Default: 10 (seconds) 

BG Channel Set 

Defines the 2.4 GHz channels to be scanned when the radio is 

contemplating a roam and needs to determine what APs are available.
