The decision algorithm used for removal of SUs from the AU's Association Database has been
improved. The current criteria for removing an SU from the list of associated SUs are:
•
A SNAP frame is received from another AU indicating that the SU is now associated with the
other AU.
•
The SU failed to respond to 100 consecutive data frames transmitted by the AU and is
considered to have "aged out".
•
During the last 6 minutes (or more) the SU failed to respond to certain frames that typically are
transmitted by the AU every 10 seconds. Since the sampling interval for this state is 10
minutes, it means that the decision to remove the SU from the Associations Database will take
place between 6 to 16 minutes from the time the SU stopped responding to these "keep-alive"
frames.
Reapplying the Country Code Parameters
The Country Code Re-apply feature enables verifying that after loading an updated Country Code the
new values will take effect.
Note that following activation of the Re-apply Country Code Values option, all parameters that are
affected by the Country Code (frequency parameters, transmit power parameters, DFS operation,
modulation level parameters, burst mode parameters) revert to their factory default values and must be
re-configured.
Better Default Values for Noise Immunity
The default value for the Pulse Detection Sensitivity has been changed to Low (unless DFS is
enabled, forcing the value to High). Note that in units where DFS is not used, after upgrade to version
4.5 the value will be forced to Low regardless of its previous value.
