Re: Let's keep all DOCSIS 3.0 Discussion in this thread, please

^-- Do you.... even know how the video and hsi operate over the lines? Docsis 3 bonds multiple channels, giving the ability to offer more bandwidth. As for the HD issue, there are plans to remove analogue signal in it's entirety (save for the basic1 plan), and move to on-request video feed -- only the channel you are watching is fed to your box at any time. IMO, I think this idea is a double edged sword..

I'll agree though, it's hard to provide docsis3 speeds to everyone, but be honest, could you build a network to provide bandwidth in excess of 50megabits to millions of subscribers, and operate it for a price that is anywhere near reasonable? I know I couldn't, not something that huge.

Not everyone will be able to be moved to DOCSIS v3 right away. This is already, for the most part, apparent(at the moment anyways).

It's hard to imagine any entity being able to supply that amount of bandwidth at any given time. But if they are selling it, they should be able to supply it. In this case, is where having a big corporation with alot of money is put to the test.

And for what it's worth, eventually it's going to come down to customers demanding it. And whether Comcast is smart with future developments, infrastructure future-proofing, and money allocating. Because to put it bluntly, if they don't they won't make it. Thats where the future is going, and thats what customers will demand eventually.

Well I guess I should point out something most people do not know. Most of the HFC in Comcast is from the Ped on the Street to the House. The only difference between Comcast and Verizon is a couple of hundred feet of HFC plant. Now I should also point out that DOCSIS 3.0 is bonding DS and US channels together. Example for your sake. 4 DS bonded channels, each DS channel being 6Mhz gives you 24Mhz using 256QAM, gives you theoretically 160Mb of DS bandwidth. You do the math. The Comcast Cable Plant is built out to 850Mhz. 24Mhz is a drop in the bucket with Comcast reclaiming analog channels back. Thats only 4 analog channels.

And no ones built to 850 Mhz either. 864 Mhz technically (industry standard is 860 or 870 Mhz), but many many systems only work up to 750 MHz, and there's even some 600, and 550 MHz systems out there.

I don't understand this phrase: Most of the HFC in Comcast is from the Ped on the Street to the House.

What are you trying to say? HFC means Hybrid Fiber Coax, so your saying most of the Hybrid Fiber Coax in Comcast is from the Ped on the Street to the House. Well that's all coax, and the fiber is brought to a node. The node converts that fiber to RF over coax, and it passes 250 - 1600 homes depending on system architecture, age, investment, etc...

And I'm trying to find Der_Idiot's post that you are replying to.
