Custom Parameter Option

The parameter Custom option is not supported. The parameter value is displayed as “Custom” when the operating system registry has been edited to set the Summit parameter to a value that is not available from the parameter’s drop down list. Selecting Custom from the drop down list has no effect. Selecting any other value from the drop down list will overwrite the “custom” value in the registry.

Roam Trigger

-65 dBm

If signal strength is less than this trigger value, the client looks for a different Ac-

 

 

cess Point with a stronger signal.

 

 

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

 

 

Parameter Option (page 11-14).

 

 

 

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 Parameter Option

 

 

(page 11-14).

 

 

 

Roam Period

10 sec.

The amount of time, after association or a roam scan with no roam, that the ra-

 

 

dio 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

 

 

Parameter Option (page 11-14).

 

 

 

BG Channel Set

Full

Defines the 2.4GHz channels to be scanned for an AP when the radio is con-

 

 

templating 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 Parameter Option (page 11-14).

 

 

 

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.

 

 

 

DFS Scan Time

120 ms.

The amount of time the radio will passively scan each DFS channel to see if it

 

 

will receive a beacon.

 

 

Recommended value is 1.5 times that of the AP's beacon period.
