Comments on news posted 2008-01-08 16:21:33: Earlier this year, Comcast CEO Brian Roberts worked the media into a lather by stating that 150Mbps connectivity would be a reality for the company "within less than a couple years." Those speeds are courtesy of DOCSIS 3. ..

Big deal

though he did illustrate to attendees how with DOCSIS 3.0, they could download a full HD copy of Batman Begins in four minutes.
After less than an hour you'll hit your monthly limit.

Makes little sense

DOCSIS 1.X will do 40 down / 10 up. If they(cable in general) would just go that far it would be a huge jump for most of us without having to replace everything. DOCSIS 3.0 is great but, even if it can do 160 down/ 120 up, will we have access to this? If they intend to do so, why can't we get 40/10 now?

Re: Big deal

They'll have the capacity to significantly raise or abolish the limit...should they choose to. And these movie transfers demonstrate their HD VOD capabilities which wouldn't apply to HSI restrictions.

DOCSIS3.0

Have to laugh at the statement that Comcast customers will have these seemingly out of this world speeds (up and down). I guess I'm one of those who will have to wait till the 2nd coming to get download of greater than 1500/256. Comcast doesn't offer digital/HD TV phone or high speed Internet technology to my area(San Francisco Bay area) yet they've milked the ratepayers for years with the claim that the rate hikes were for upgrading their offering. I currently have Earthlink/COVAD at 3000/384 along with LPVoice telephone and a VOIP line which runs about as well as a blind- threee-legged dog BUT its better than Comcast AT&T or the others have offered.
some day we will join the ranks of the 21st century technology but till then.............

In FIOS areas.......

by all means upgrade to DOCSIS 3 and make those areas a proving ground for high speed offerings. But elsewhere save your money and take your time. AT&T has given Comcast a free pass where they compete, and they had better take advantage of this. No need for DOCSIS 3 in any of those areas.

Really? Hmm, I'm in the S.F. Bay Area and have HD TV, Phone and High Speed Internet choices from Comcast.

I didn't realize the folks in Hayward had been left out of these Comcast services.

It is shared bandwidth. 40Mb is shared by 250 (OOL)-2000 households. »en.wikipedia.org/wiki/Hybrid_Fibre_Coaxial. They don't want one user to hog all bandwidth on the node. Although OOL Boost with 30Mps almost allows it.

And how will that change with 3.0?

The nice thing..

The nice thing about living in Comcast's home market is that it means we'll likely be part of that 20% that gets the upgrade this year. I have FiOS right now but I'd love to see the competition in the internet realm really heat up.

Re: In FIOS areas.......

I disagree, because AT&T is acting the way they are, that is precisely the reason Comcast should upgrade some of those areas first.

Re: Makes little sense

480 Mbps will be shared between 250-2000 houses. It is much better. BTW, I think, that is why they still offer only 160Mps, not full 480Mpbs, so one user cannot overload the node.

With DOCSIS3.0 users will share +480Mbps instead of 42Mbps. ALL 2.0 cable modems sync at 48Mbps down (5360 Ksym/sec) 20Mbps up (2560 Ksym/sec) Time slots (provisioning) is what defines your speed.

10 out of 40 is 1/4 of the bandwidth by one person.

160 out of 480 is 1/3 of the bandwidth by one person.

It is the same problem just a bigger pipe. Percentage wise things are worse not better. 1/3>1/4

Re: In FIOS areas.......

This would only make sense if Comcast had a fiduciary responsibility to bury their competition. They don't. They're in business to make money for their stockholders and blowing cash with no competitive reason would be malpractice.

DOCSIS 3.0 does not involve VOD.

No because people will download the same amount of data, just faster.

Maybe, but I would bet that is a bad assumption. With the coming shift to HD DVD or Blueray (regardless of which wins out) people will be downloading 25-50gig images instead of 4.4-9gig images. With the switch to DTV in Feb 09 will will be seeing a lot more TV series being sent in HD rather than smaller standard NTSC (yes I know cable does not have to change but I bet it will). Lower resolution stuff in general has been dropping (VCDs are relatively rare already). Even web pages themselves are becoming (or have become) much higher resolution (larger). P2P just keep on growing. Every time more bandwidth becomes available people have found a way to fill it. I do not think that is a trend that is going to change anytime soon. As far as pure data is concerned look at the explosive increases in data set sizes every time a new media became popular: Cds, DVDs, and now whichever format wins out.
