Default

 

Function

 

 

 

 

 

If signal strength is less than this trigger value, the client looks for a different Access Point with a

Roam

-65

stronger signal.

 

 

Trigger

dBm

Options are: -50 dBm, -55, -60, -65, -70, -75, -80, -85, -90 dBm or Custom.

 

 

Note:

Available options may vary by SCU revision.

 

 

 

Roam

 

The amount by which a different Access Point signal strength must exceed the current Access Point

5 dBm

signal strength before roaming to the different Access Point is attempted.

Delta

 

Options are: 5 dBm, 10, 15, 20, 25, 30, 35 dBm or Custom.

 

 

 

 

 

Roam

BG: 10

The amount of time, after association or a roam scan with no roam, that the radio collects Received

sec.

Signal Strength Indication (RSSI) scan data before a roaming decision is made.

Period

A: 5

Options are: 5 sec, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 seconds or Custom.

 

sec.

 

 

 

 

 

 

 

 

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.

BG

 

Options are:

 

Full (all channels)

Channel

Full

Set

 

1,6,11 (the most commonly used channels)

 

 

1,7,13 (for ETSI and TELEC radios only)

 

 

Custom.

 

 

 

 

DFS

 

Support for 5GHZ 802.11a channels where support for DFS is required.

Off

Options are: On, Off.

Channels

 

Note:

Not supported (always off) in some releases.

 

 

 

 

 

 

 

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

Ad Hoc

1

selected that is not supported by the by the radio, the default value is used.

 

 

Channel

Options are:

 

 

 

1 through 14 (the 2.4GHz channels)

 

 

36, 40, 44, 48 (the UNII-1 channels)

 

 

 

 

 

When set to On and the current connection to an AP weakens, the radio aggressively scans for

 

 

available APs.

Aggressive

On

Aggressive scanning works with standard scanning (set through Roam Trigger, Roam Delta and Roam

Scan

 

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
