10. Set the following Channel Settings for the access point’s 5.0 GHz and 2.4 GHz radio bands:
Select the +Add Row button to add Area Based Channel Settings.
Set the following Area Based Channel Settings for the access point:
Select OK to update the Smart RF Channel and Power settings for this policy. Select Reset to revert
to the last saved configuration. The Smart RF policy can be invoked at any point in the configuration
process by selecting Activate SMART RF Policy from the upper, left-hand side, of the access point
user interface.
11. Select Scanning Configuration. Ensure Activate SMART RF Policy remains selected so the
screen’s parameters can be updated. Additionally, the Smart RF configuration cannot be
applied to the access point profile unless this setting remains selected.
5 GHz Channels Use the Select drop-down menu to select the 5.0 GHz channels used in Smart RF scans.
5 Channel Width 20 MHz 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 2.4 GHz and 5.0 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 the automatic
assignment of channels to working radios to avoid channel overlap and avoid interference from
external RF sources. The default setting is 40 MHz.
2.4 GHz Channels Use the Select drop-down menu to select 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 2.4 GHz and 5.0 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. 20 MHz is
the default setting.
Area Use the text area to provide a name for the area being configured.
Band Use the drop-down menu to select the radio band to use in the area being configured.
Channel List Use the Select drop-down menu to select the channels used in Smart RF area based channel
settings.
