Well, sort of. The aircraft is equiped with a pico cell (miniature
cell tower)
that instructs the phones to reduce their power output to the minimum.
There's
no active interference protection.

The interference protection is achieved by that action of "reducing
power". Which is caused by the picocell. It's just different ways of
saying the same thing.

What kind of mobile phone system is used in Niue, BTW? I remember
reading that it is quite different from your standard provider.
