Appendix C: SCU For 802.11b/g Radio

Global Tab

The Global settings tab allows you to define radio and security settings that apply to all pro- files, along with settings that apply specifically to the SCU. The Global settings in the table below can be edited in SCU:

Table C.2 Global Tab

Global Setting	Description	Value	Default
Roam Trigger	If RSSI from AP is less than roam	dBm: -50, -55, -60, -65,	-75
	trigger value, radio performs roam scan	-70, -75, Custom
	or probes for an AP with stronger
	signal.
Roam Delta	Amount by which second AP’s RSSI	dBm: 5, 10, 15, 20, 25,	10
	must exceed the moving average RSSI	30, 35, Custom
	for the current AP before the radio will
	attempt to roam to a second AP.
Roam Period	Following an association or roam scan	Seconds: 5, 10, 15, 20,	10
	(with no roam), the number of seconds	25, 30, 35, 40, 45, 50,
	the radio collects RSSI scan data before	55, 60, Custom
	considering roaming.
BG Channel Set	Defines the 2.4 GHz channels to be	Full (all channels)	Full
	scanned when the radio is set to roam	1, 6, 11
	and needs to determine what APs are	1, 7, 13
	available.	Custom
DFS Channels	Reserved	Off, On	Off
Aggressive Scan	When this setting is On and the current	Off, On	On
	connection to an AP becomes unrelia-
	ble, the radio scans for available APs
	more aggressively. Aggressive scan-
	ning complements and works in con-
	junction with the standard scanning
	that is configured through the Roam
	Trigger, Roam Delta, and Roam Period
	settings. It is recommended that
	Aggressive Scan is left On unless there
	is significant co-channel interference
	because of overlapping coverage from
	APs on the same channel.
