In January, I wrote about Brian Roberts’ CES keynote, in which he talked about wideband. In the spring, Comcast deployed DOCSIS 3.0 in the Minneapolis/St. Paul market. This week, Comcast deployed wideband service to residential homes and businesses in parts of New England, including the Boston Metropolitan region and Southern New Hampshire, as well as areas of Philadelphia and New Jersey. In addition to the new speed tiers, Comcast also is increasing speeds for most of its existing customers.
I walk though all this because many of the technology deployments we discuss on this blog are all part of a larger pattern. DOCSIS 3.0 uses channel bonding to join 6 MHz channels together to provide greater bandwidth. In order to free up channels to provide such services, cable operators have to manage their networks.That’s why you see analog channels moved to the digital tier, as I discussed again recently.
Comcast expects to reach more than 10 major markets and pass nearly 10 million homes and businesses in the next several months.
