Here in New Zealand there are no plans to introduce DAB as far as I'm aware. If disaster strikes internet and mobile phone is out and the only communication was done by a couple of old fogies of the AREC (Amateur Radio Emergency Corps) and there were not enough of them. I remember the old manual phone exchanges and party lines and later using satelites to phone to the other side of the planet with a few seconds lag. Now we've got fibre optics but Russia has mapped all the lines and in case of mayhem the lines can/will be easily cut.
The whole lot is becoming more and more fragile - we need only to look at the JIT (Just In Time) supply chain. Covid turned that upside down and we're all suffering the fallout from that.
Our daughter is in water treatment management and they've gone from using UHF communication to the internet using mobile celltowers. Bad move, in the floods the celltowers were flooded and shrted out so no communication. But it's all about saving a penny and not about building in redundancy.
