Yes you're missing the point that the alerts need to reach everyone
well in advance of the fire being within many kms of the property.
That's what didn't happen. 'Early' is a relative term and is
insufficient for the types of fires that happened on that Saturday.
And no one realised it. If the tower is down, it's too late to leave.
But I was told that the mobile network was still working in the
Labertouche fires.
Canberra had a different experience. You and BRD will know better
about that one.
Landlines are possibly going to go out first to some homes depending
on where the phone cable is. If it's on poles, forget it if they lead
through the fire zone. At least mobile radio towers have a bit better
chance, no? Some radio bands may be better, so maybe that is the type
of connection that is needed to get to individual homes. Maybe some
of that recovered bandwidth when the analog tv gives up could be used
for emergency radio services in the bush. I seem to recall such a
thing in the US that did interrupt all broadcast tv. Specialty radios
might be worth it for broadcast. ABC is one thing, but it wasn't
nearly granular enough. There needs to be evacuation directions, as
in what roads are still safe to use. Otherwise people could be
driving straight into the fire or one nearby.
