Wouldn't it be more forward-thinking to go for 5G?

No, because the emergency services contract (which this is piggy-backed
upon) is 4G.

Is this something to replace the tetra based network in the UK?

Yes. And it's also much delayed. But that's not really a surprise for a
large government IT project!

It's also going to be a total waste of time and money. Tetra just
worked, why change it..?

I think the problem is it's proprietary, and rather old. Replacing worn
out equipment and paying ongoing licence fees, was regarded as less
effective than using an 'open source' idea like 4G.

Wasn't it also the lack of development of the standard and basically
being stuck on GPRS like speeds?

What's concerning is that they are still rolling out a 4G solution when
5G is already here...

Not that old in radio terms. Plod was still using motorola analogue trunking
systems only 15 years ago - I used to listen to them on a scanner. Tetra is
a lot newer than DAB!
