DOCSIS 3.0 Cometh


Don’t think you’ll be able to stream HD Video to your PC or TV via the Internet? Take a look at DOCSIS 3.0 which will deliver speeds that are multiples of the HD bit rates.

Comcast’s, chief technology officer Tony Wernersays his company will be testing the technology this year. CableLabs certification of equipment will also begin this year. That means in 2008 it is likely there will be 3.0 modems available to deploy.

Werner says it will cost 70% less to offer 6 mbps service using 3.0 vs 2.0 equipment, and about the same for 100 mbps on 3.0 as 6 mbps on 2.0.

Comcast CEO Brian Roberts demoed “real” DOCSIS 3.0 at the NCTA show the other day.

While the higher speed service will require more of the cable’s bandwidth, using the current bandwidth should produce speeds of almost 40 mbps, or 2X the HD video bit rate.

All this may not lead to streaming HD over the Global Internet in the next two years, but it is clear we are in shouting distance of seeing it within a service provider’s network.

    Apparently pressured by competition coming from FiOS, cable companies are getting aggressive about deploying 3.0.

    Comcast senior vice president of new-media development Steve Craddock said that for a couple $Billion, which he described as chump change, the cable industry can cover the nation. The Comcast time frame has been moved into 2008 from 2009-2010.

    Not alone, Cox Communications VP of technology Jay Rolls is comfortable with the Comcast timeline.

    CableLabs will start testing in October.

    I was just visiting someone with Optimum Online service in NJ, and they’re already getting 15/2 Internet service for the same price I pay Charter for 5. Plus, for an extra $15, they could upgrade to 30.

    What’s even worse, is Verizon is going to install FiOS service on the street next month (it’s marked for digging already) and going to charge $5 more for 15 and more than twice as much for 30. Hardly seems like the right market to compete in for Verizon.
