You should disable this option unless you are both capable
and willing to ensure your system will remain regulatory
compliant with the features available under this option.
Some options may still be under heavy development and
for whatever reason regulatory compliance has not or
cannot yet be verified. Regulatory verification may at
times only be possible until you have the final system
in place.

This option should only be enabled by system integrators
or distributions that have done work necessary to ensure
regulatory certification on the system with the enabled
features. Alternatively you can enable this option if
you are a wireless researcher and are working in a controlled
and approved environment by your local regulatory agency.
