Radio Frequency Scan Selection List
The SM or BHS scans complete spectrum as per Full Spectrum Band Scan feature. SMs or BHS first boot
into the smallest selected channel bandwidth (10 MHz, if selected) and scan all selected frequencies
across both the 5.4 GHz and 5.7 GHz frequency bands.
After this scan, if a wider channel bandwidth is selected (20 MHz), the SM/BHS automatically changes
to 20 MHz channel bandwidth and then scans for APs/BHSs. After the SM/BHS finishes this final scan it
will evaluate the best AP/BHM with which to register. If required for registration, the SM/BHS changes
its channel bandwidth back to 10 MHz to match the best AP/BHM.
The SM/BHS will attempt to connect to an AP/BHM based on power level (which affects the modulation
state), channel bandwidth (which affects throughput) and number of SM/BHS registrations to the
AP/BHM (which affects system contention performance).
If it is desired to prioritize a certain AP/BHM over other available APs/BHMs, operators may use the
Color Code Priority feature on the SM/BHS. Utilization of the Color Code feature on the AP/BHM is
recommended to further constrain the AP selection.
If the SM does not find any suitable APs/BHMs for registration after scanning all channel bandwidths,
the SM restarts the scanning process beginning with the smallest configured channel bandwidth.
Selecting multiple frequencies and multiple channel bandwidths impacts the SM/BHS scanning time. The
biggest consumption of time is in the changing of the SM/BHS channel bandwidth setting.
The worst case scanning time is approximately two minutes after boot up (SM/BHS with all frequencies
and channel bandwidths selected and registering to an AP/BHM at 10 MHz). If only one channel
bandwidth is selected the time to scan all the available frequencies and register to an AP/BHM is
approximately one minute after boot up.
Other scanning features such as Color Code, Installation Color Code, and RADIUS authentication are
unaffected by the Full Band Scan feature.
