Little problem called the Shannon Capacity of a channel.

Didn't we go over this with modems back in the 2400bps days? "Up the
speed? Can't be done."

Different issue.

2400 baud was nowhere near the bandwidth limit of twisted pair phone
lines,

and yet, it was claimed to be.

Like I said, didn't we go over this with modems once?


it was merely the limit of primitive but simple frequency shift and phase
shift signalling used at the time

So, the claims of absolute limits weren't actually claims of absolute
limits, even though people said they were. The limitations described
were actually limitations of then-current technologies.

Gotcha. So whenever someone claims an absolute technological limitation
("the sound barrier was like a brick wall in the sky"), one should
always append to that claim the phrase "...with current technology".

Like I said, didn't we go over this once before?

Why don't you read up on communications theory and figure out what is going
on.

Ignorance can be cured.
Stupidity is forever.
