I remember reading years ago about the limits of copper, everytime they managed to increase the dialup connection speed they said it could go no higher and pretty much the same things were said when ADSL first appeared over 10 years ago.”
We have certainly hit the limits now. i remember my old US robotics courier modem, in fact I have still got it, all the screaming and bleeps when it connected, I do miss that sound even after almost 11 years when I stopped using it. i also had it updated to 56k.
when I first came onto broadband, I thought that 512kbits was great, so much faster than what I used to use, but also so much more expensive, I am glad my lodger agree to pay half, if she did not then we would not have had broadband at that time.
But have things really improved in all those years?
at that time we had no restrictions, traffic management did not exist, it was a always on unlimited system. My dial up at the time had limits, so many hours a day a day, so going to a system with no limits was great.
Now we gone back to full circle, the speed may be faster, well sometimes, but with so much traffic managment I wonder if we are really better off.
Thankfully I got a ISP that don't have any restrictions, but it have been slowing down over the last few days.

The transmission methods used are still based on the same premise when they were invented I suppose!”
A different thing, a aerial is a aerial at the end of the day, sure they are made to receive different frequencies, but a aerial don't no the difference between a carrier wave that carries analogue info to one that carries digital info
The tech part is at the transmission source and the equipment that is receiving.
I remember when I used a CD radio years ago and I used to muck around with aerials, even making my own. I wish now I went in for HAM radio in some ways, but they seem like a load of snobs. My nephew went in for it but then never bothered with it once he got his licence.
