@duckDecoy:
I'm don't really understand all this stuff, so I have a question.
We don't currently have fiber, still on VDSL. We've been trying to get it but are having big issues (needed an OHUG and everything is going wrong). Should we just wait and jump on 5G when it comes? I guess I am asking, for a typical household its 5G perfectly adequate or is fiber better?
Fibre will always be better. 5G will be good if you can't get fibre - also expect it to cost more and have less allowance (as in don't expect unlimited plans on 5G).
