SmartRoam periodically scans for access points which belong to the current ESS (having the same SSID and security settings at the currently associated AP.) The results are then searched for an AP with a 'stronger' signal (higher RSSI) than the current AP. If the search is successful, SmartRoam triggers a disconnection from the current AP and a connection to the one selected from the scan results.

Since moving between access points are a time-consuming process which can negatively impact throughput, SmartRoam employs a delta value to ensure that the move only occurs if there would be a significant gain in signal strength. When searching the results of a scan, SmartRoam only considers those APs whose RSSI exceeds that of the currently associated AP by at least the delta value.

Note: RSSI is reported in two different ways: when accessed through WebManager, you will be given the value of a single, instantaneous sample versus when you access the RSSI roaming state through the CLI, where the RSSI value given is averaged over time.

RSSI Delta

The minimum difference (in dBm) between the current RSSI and the RSSI

 

of any access point in the scan results before it will be considered as a

 

roaming candidate. The configured value will actually be used for the high-

 

power delta. The roaming delta is cut in half for RSSI below -50dBm. The

 

value for the low-power delta will be derived from the configured one by

 

dividing it by two. Default value: 24dBm, range: 14 - 24dBm. When

 

searching the results of a scan, SmartRoam only considers those APs

 

whose RSSI exceeds that of the currently associated AP by at least the

 

delta value. Since moving between access point is a time-consuming

 

process which can negatively impact throughput, SmartRoam employs a

 

delta value to ensure that the move only occurs if there would be a

 

significant gain in signal strength.

 

 

Debugging Level

Set the verbosity level for printing WLAN Link messages to the TLOG

 

(Default is Info).

 

 

Active Channel Scan Time

Set the amount of time, in milliseconds, the radio will dwell on each

 

individual channel when performing an active scan. During active scanning,

 

the radio transmits probe requests and gathers probe responses from other

 

devices. The range of values is 50 to 150 msec.

 

 

Passive Channel Scan

Set the amount of time, in milliseconds, the radio will dwell on each

Time

individual channel when performing a passive scan. During passive

 

scanning the radio does not transmit probe requests, instead relying on

 

beacons sent by other devices. The range of values is 100 to 400 msec.

 

 

Radio Band Selection

Select the band(s) on which the radio will operate. Options are 2.4 GHz

 

only, 5 GHz only or Dual band.
