BG Channel Set
Value
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
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
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)
Defines the 2.4 GHz channels to be scanned when the radio is
contemplating a roam and needs to determine what APs are available.
