Country Code Learning by SU
This feature support simplified installation and updates processes by
enabling the SU to adapt the Country Code used by the AU.
The AU advertises its country code in every beacon and association
response message. Upon synchronization the SU shall check if its
country code and the country code received from the AU are the same.
If they are not the same and the Country Code Learning by SU is
enabled, the SU shall use the AU’s country code: the country code
derived limitations shall be forces and the following parameters shall be
set according to new country definitions:
! Maximum TX Power (per modulation level) shall be set to the
maximum defined by country code.
! TX Power (per modulation level) shall be set to the maximum defined
by country code.
! The Modulation Level shall be set to the maximum modulation level
defined by country code.
! The Multicast Modulation Level shall be set to the minimum
modulation level defined by country code.
! The Burst Mode shall be set to enable if the country code supports
burst mode, and the burst duration shall be set to default.
After country code learning (adaptation) the unit is automatically reset.
Before this automatic reset, if the unit is running from shadow version,
the versions must be swapped and the running version must be set as
main. This is done to avoid returning to the previous version, which
shall happen automatically after the reset.
The default is Enable.
