Click the Configure button, the Network tab and the Roaming sub-tab to configure Roaming. The screen differs
depending on whether the unit is configured as a BSU or as an SU.
BSU Screen
Enable or disable the Roaming feature by clicking on the Enable Roaming Status check box. The default value
is disabled (clear). If you enable roaming, you may set the Announcement Period (from 25 to 100 ms, default is
100 ms).
On this screen you may also enable or disable the Multi-Frame Bursting (default value is enabled).
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.
