The little I know about cellular is that the handset only broadcasts
to the cells when its on. Of course, 'on' and 'off' might mean
different things on a hand-held with limited battery life, and a
mobile that's connected to a large battery with a generator (car).
But it doesn't make sense to have the even the mobile system constantly
communicating with cells and getting hand-offs when the operator
has switched it 'off' and isn't using it- it'd be taking up bandwidth
for no reason at all. And we all know that cellular bandwidth is
in short supply.
