Auto Scanning Table
An SU scans all available channels for a given bandwidth during roaming. In order to reduce the number of channels an
SU has to scan and thus decrease the roaming time, a channel priority list that tells the SU what channels to scan is
implemented. Each channel in the channel priority list is specified with its corresponding bandwidth and the priority with
which it should be scanned, either “Active” (standard priority), “Active High” (high priority), or “Inactive”.
An SU will scan all channels indicated as “Active” during roaming. However, it will scan active channels indicated as
“High Priority” before scanning active channels indicated as standard priority. Channels that are not going to be used in
the wireless network should be configured as “Inactive” so that the SU can skip over those channels during scanning
saving this way time.
A BSU broadcasts the channel priority list to all valid authenticated SUs in its sector. It re-broadcasts the channel priority
list to all SUs every time the list is updated on the BSU.
