Global Parameters
Parameter Default Function
Roam
Trigger -65
dBm
If signal strength is less than this trigger value, the client looks for a different Access Point with a
stronger signal.
Options are: -50 dBm, -55, -60, -65, -70, -75, -80, -85, -90 dBm or Custom .
Note: Available options may vary by SCU revision.
Roam
Delta
5 dBm
The amount by which a different Access Point signal strength must exceed the current Access Point
signal strength before roaming to the different Access Point is attempted.
Options are: 5 dBm, 10, 15, 20, 25, 30, 35 dBm or Custom .
Roam
Period
BG: 10
sec.
A: 5
sec.
The amount of time, after association or a roam scan with no roam, that the radio collects Received
Signal Strength Indication (RSSI) scan data before a roaming decision is made.
Options are: 5 sec, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 seconds or Custom .
BG
Channel
Set
Full
Defines the 2.4GHz channels to be scanned for an AP when the radio is contemplating roaming. By
specifying the channels to search, roaming time may be reduced over scanning all channels.
Options are:
Full (all channels)
1,6,11 (the most commonly used channels)
1,7,13 (for ETSI and TELEC radios only)
Custom .
DFS
Channels
Off
Support for 5GHZ 802.11a channels where support for DFS is required.
Options are: On, Off.
Note: Not supported (always off) in some releases.
Ad Hoc
Channel
1
Use this parameter when the Radio Mode profile parameter is set to Ad Hoc.
Specifies the channel to be used for an Ad Hoc connection to another client device. If a channel is
selected that is not supported by the by the radio, the default value is used.
Options are:
1 through 14 (the 2.4GHz channels)
36, 40, 44, 48 (the UNII-1 channels)
Aggressive
Scan
On
When set to On and the current connection to an AP weakens, the radio aggressively scans for
available APs.
Aggressive scanning works with standard scanning (set through Roam Trigger, Roam Delta and Roam
Period). Aggressive scanning should be set to On unless there is significant co-channel interference
due to overlapping APs on the same channel.
Options are: On, Off
