🇦🇺 Navy Ship Causes Internet Outage In Parts Of 🇳🇿

So this Aussie Navy ship that was visiting us lately was putting out
enough power in its navigation radar to cause interference to internet
users and radio reception across a significant part of the country.

Quote from an official:

    “Some spectrum bands are free of charge and available for anyone
    to use – such as the shared spectrum bands for Wi-Fi and
    Bluetooth,” said Dan O’Grady, the ministry’s manager of radio
    spectrum policy and planning.

    “The interference that occurred on Wednesday was in one of these
    shared bands.”

But those shared bands are not a complete free-for-all: there are
supposed to be limits to the power that transmitters are allowed to
have, precisely to avoid this sort of interference.
