In the Radio tab of the SM, you may set the following parameters.

Frequency Scan
Selection List
Check any frequency that you want the SM to scan for AP
transmissions.
Prior to System Release 12.0.3, the PMP 450i SM boot sequence
included loading the current channel bandwidth (10 MHz or 20
MHz, but not both) and frequency band and scanning selected
frequencies in the respective frequency band. After a scan of all
the selected frequencies, the SM can attempt to register to the
best AP based on the SM’s current configuration.
With the introduction of the Full Spectrum Band Scan feature in
12.0.3, SMs first boot into the smallest selected channel
bandwidth (10 MHz, if selected) and scan all selected frequencies
across the 5.7 GHz frequency bands.
After this scan, if a wider channel bandwidth is selected (20 MHz),
the SM automatically changes to 20 MHz channel bandwidth and
then scans for APs. After the SM finishes this final scan it will
evaluate the best AP with which to register. If required for
registration, the SM changes its channel bandwidth back to 10
MHz to match the best AP.
The SM will attempt to connect to an AP based on power level
(which affects the modulation state), channel bandwidth (which
affects throughput) and number of SM registrations to the AP
(which affects system contention performance).
If it is desired to prioritize a certain AP over other available APs,
operators may use the Color Code Priority feature on the SM.
Utilization of the Color Code feature on the AP is recommended to
further constrain the SM’s AP selection.
If the SM does not find any suitable APs for registration after
scanning all channel bandwidths, the SM restarts the scanning
process beginning with the smallest configured channel
bandwidth.
By default, System Release 12.0.3 SMs are configured to scan all
available frequencies and all available channel bandwidths. This
allows operators to install SMs and allow them to register with no
pre-configuration or staging required. SMs upgraded from a
previous release to 12.0.3 retain frequency and channel
bandwidth configuration.
Selecting multiple frequencies and multiple channel bandwidths
impacts the SM scanning time. The biggest consumption of time is
in the changing of the SM channel bandwidth setting.
