Re: Where are the...
said by openbox9  :Whiners complaining about all of the money that Comcast is raking in, but not upgrading their infrastructure? for at least a few more years, by the speeds currently provided by DOCSIS 1.x (or in Cablevision's case 2.0) networks. Still on DOCSIS 1.xx??
Long over due for "upgrading their infrastructure"

said by hopeflicker :Still on DOCSIS 1.xx?? Long over due for "upgrading their infrastructure" What would they upgrade to? DOCSIS 2.0 has the same download channel capacity as 1.x, only the upstream gets improved from 9mbps to 27mbps. It provides no gains in video distribution, no significant gains in signal quality, and still required a complete CMTS card replacement.
The cable companies that have DOCSIS 2.0 only have it from initial deployments, no company in the industry upgraded because the ROI for 2.0 was crap.
3.0's big advantage is it allows MSOs to start deploying things like Switched Digital Video, which matters even more to cable companies than HSI speeds. |

The cable companies that have DOCSIS 2.0 only have it from initial deployments, no company in the industry upgraded because the ROI for 2.0 was crap. CableVision (who is my connectivity provider) was DOCSIS 1.1 at 10/1. They DID spend the money to offer DOCSIS 2.0 (BOOST) at initially 30/2 (now 30/5) and bumped their DOCSIS 1.1 to 10/2 (and now 15/2). Thus your "Spend the ROI Money" claim is inaccurate. So is your DOCSIS 1.1 Download speed max being the same as DOCSIS 2.0 max since for me to get BOOST (DOCSIS 2.0) my DOCSIS 1.1 modem had to be replaced with a DOCSIS 2.0 modem (since the old one did not have the download speed capability). |

Comcast ran into the same problem with PowerBoost with certain older modems, particularly the earlier Surfboards and RCA modems where not capable of delivering speeds at the full DOCSIS 1.1 rates. As for the download speeds being the same, that's a fact. See:
