8. Refer to the Power Settings field to define Smart RF recovery settings for either the selected
5.0 GHz (802.11a) or 2.4 GHz (802.11bg) radio.
Set the following Channel Settings for the 5.0 GHz and 2.4 GHz radios:
Set the following Area Based Channel Settings for the Smart RF policy:
Select OK to update the Smart RF Channel and Power settings for this policy. Select Reset to revert
to the last saved configuration.
9. Select the Scanning Configuration tab.
5.0 GHz Minimum Power Use the spinner control to select a 1 - 20 dBm minimum power level for Smart RF to assign to a
radio in the 5 GHz band. 4 dBm is the default setting.
5.0 GHz Maximum Power Use the spinner control to select a 1 - 20 dBm maximum power level Smart RF can assign a radio in
the 5 GHz band. 17 dBm is the default setting.
2.4 GHz Minimum Power Use the spinner control to select a 1 - 20 dBm minimum power level Smart RF can assign a radio in
the 2.4 GHz band. 4 dBm is the default setting.
2.4 GHz Maximum Power Use the spinner control to select a 1 - 20 dBm maximum power level Smart RF can assign a radio in
the 2.4 GHz band. 17 dBm is the default setting.
5.0 GHz Channels Use the Select drop-down menu to define the 5 GHz channels used for Smart RF assignments.
5.0 Channel Width 20 and 40 MHz channel widths are supported by the 802.11a radio. 20/40 MHz operation (the
default setting for the 5 GHz radio) allows the Access Point to receive packets from clients using 20
MHz of bandwidth while transmitting a packet using 40 MHz bandwidth. This mode is supported for
11n users on both the 2.4 and 5 GHz radios. If an 11n user selects two channels (a Primary and
Secondary channel), the system is configured for dynamic 20/40 operation. When 20/40 is
selected, clients can take advantage of wider channels. 802.11n clients experience improved
throughput using 40 MHz while legacy clients (either 802.11a or 802.11b/g depending on the
radio selected) can still be serviced without interruption using 20 MHz. Select Automatic to enable
automatic assignment of channels to working radios to avoid channel overlap and avoid
interference from external RF sources. 40MHz is the default setting.
2.4 GHz Channels Set the 2.4 GHz channels used in Smart RF scans.
2.4 GHz Channel Width 20 and 40 MHz channel widths are supported by the 802.11a radio. 20 MHz is the default setting
for 2.4 GHz radios. 20/40 MHz operation (the default setting for the 5 GHz radio) allows the Access
Point to receive packets from clients using 20 MHz of bandwidth while transmitting a packet using
40 MHz bandwidth. This mode is supported for 11n users on both the 2.4 and 5 GHz radios. If an
11n user selects two channels (a Primary and Secondary channel), the system is configured for
dynamic 20/40 operation. When 20/40 is selected, clients can take advantage of wider channels.
802.11n clients experience improved throughput using 40 MHz while legacy clients (either
802.11a or 802.11b/g depending on the radio selected) can still be serviced without interruption
using 20 MHz. Select Automatic to enable automatic assignment of channels to working radios to
avoid channel overlap and avoid interference from external RF sources. 20MHz is the default
setting.
Area Specify the deployment area assigned to the listed policy when deployed a means of identifying the
devices physical locations.
Band Specify the radio band, either 2.4 GHz or 5 GHz, for the Smart RF policy assigned to the specified
area.
Channel List Specify the channels associated with the Smart RF policy for the specified area and band.
