Assuming you're not talking about HFC, POTS might be capable of shoving through signals into the dozens of Megahertz, yes. Maybe even into the low hundreds. That would give you a speed near enough 1 Gbps.
But over a distance of, over your typical barely twisted 0.40mm copper wrapped in nothing put some PVC and PE, maybe three or four dozen metres. And that's with G.Fast which is not even seeing any large deployments quite yet.
And if you're talking about HFC, that is a shared medium. So, sure it can do massive speeds. You can shove, over let's say the 800 Mhz you have, about 5 Gbps, sure, if there's no TV on it. But it's going to be contented across all the other users on the same circuit, which might be in the hundreds.
- lstamour 13y agoTrue. Let's call 5gbps over cable a last ditch attempt to offer fibre-expense plans to places cable companies have no intention of upgrading to fibre. They'll start by using fibre as a way of raising prices across the board, of course ... and that's what we really rebel against. It's not the bandwidth available as much as how there's a line in other countries (as shown in those graphs) of 100mbps speeds for under $40. We'll never see that for a good 10 years here... if ever. They do want to say that "today's speeds are good enough" -- read as: we're not dropping prices anytime soon for current speeds.
