Comcast gave a bit more detail on the state of their DOCSIS 3.0 upgrades at the CableNEXT Conference this week in Santa Clara, California. Comcast CTO Tony Werner told attendees that the company hopes to have Docsis 3.0 technology in place in around 20 percent of the company’s footprint by the end of next year. DOCSIS 3.0, as we’ve frequently noted, should allow the operator to eventually offer speeds in excess of 100Mbps.

Werner wouldn’t elaborate on which markets will see deployment first, but you can be sure they’ll mirror FiOS deployment. You can also be sure that users won’t see full capacity at first, the initial offerings being in the 20-50Mbps range. What about upstream speeds? Light Reading says the upgrades will focus on downstream bandwidth at first:
Although the full Docsis 3.0 specification calls for the bonding of at least four upstream and four downstream channels, initial Comcast deployments will be a downstream-only affair. That’s more a reflection of the status of upstream channel bonding technology than one of Comcast’s Docsis 3.0 service strategy. Docsis 3.0 upstream channel bonding won’t likely won’t be ready for prime time until late next year or possibly 2009.
That’s definitely going to initially hurt Comcast’s fight against FiOS, as Verizon just started offering symmetrical 15Mbps and 20Mbps service wherever FiOS is available.
