Use of Broadcast Spectrum

[bacco007]

Continuing the discussion from Sky News:

@bacco007

As I’ve said before, broadcast spectrum is a valuable, finite asset that needs to be managed properly - no-one (community, commercial, government broadcasters) should have any more or less right to access to it - before everyone jumps on me, this isn’t a reflection on the quality of their product - but gone are the days of needing to allocate a large chunk of bandwidth for a single channel

Rather then fill threads like the Sky News one with an off-topic conversation, I thought its time to create a new thread so we can discuss the use of broadcast spectrum (be it TV, AM, FM or Digital Radio)

I suspect TV broadcasters are going to have to share multiplexes if/when we transition over to DVB-T2 and HEVC (because of the money that can be made by selling off even more spectrum to the telcos in the process), but that worthy discussion is for another topic.

And here is that topic

I agree - it would allow for a more efficient use of the spectrum (and you’d buy ‘space’, potentially across multiple multiplexes), a bit like how Freeview in the UK works

But the UK can somehow manage with 390MHz Emergency Service Radio, that’s never going to work here.

450MHz in the UK is DTV where as it’s two way band here and VHF high band is used for two way comms where as here it’s used for TV.

Use of slots and other stuff also help over there, on TETRA which is used in the UK and some places here, it has 4 slots meaning 4 users can be talking on the same channel where as P25 which is used here and in the US, only has 1 slots.

For spectrum efficiency, we need to upgrade almost all radios, and then we will have space which is never going to happen.

Is AM radio dead? Tesla thinks so!

All the cheap crap been Imported is certainly killing the AM band at a fast rate due to the rapid increase in the noise floor, and the ACMA don’t seem to want to o do anything about it
