With the addition of the Sacramento region today, Comcast has completed its DOCSIS 3.0 deployments in California, at least of its 50 Mbps tier.

While Comcast will be close to reaching its stated goal of having D3 rolled out across its entire footprint by year’s end, the nation’s largest cable operator and ISP is also gearing up for 100 Mbps deployments – which the company first launched last year in the Minneapolis/St. Paul area – later this year.

As for the Golden State, Comcast previously deployed wideband in the San Francisco Bay Area and in several portions of the Central Valley, including Davis, Roseville and Placerville. Comcast has now rolled out DOSCIS 3.0 to nearly 80 percent of its footprint across the nation.

Comcast’s Extreme 50 tier, which has upload speeds of up to 10 Mbps, is now available to residential homes and businesses in all regions of Sacramento County, including:  Antelope, Carmichael, Citrus Heights, Elk Grove, Elverta, Fair Oaks, Folsom, Galt, Gold River, Mather, North Highlands, Orangevale, Rancho Cordova, Rio Linda and Sacramento.

With a subscription to Comcast’s cable service, Extreme costs $99.95 per month, while the business-class service is priced at $189.95.

Comcast’s Ultra tier, which has been deployed in other markets with a downstream speed of 22 Mbps down and 5 Mbps up, isn’t available in the Sacramento region. A spokesman for Comcast said this morning that the company was focusing on different products in different markets to assess consumer demand.

Comcast is using cable modems from Arris and Cisco in the Sacramento deployment and cable modem termination systems from Motorola.

As it has done in other markets, Comcast also increased the speeds for its existing Performance tier residential customers, who now benefit from doubled downstream speeds of up to 12 Mbps and 2 Mbps, respectively.

Comcast’s California region, based in Livermore, serves more than 2.3 million customers in northern and central California. Comcast said it employs more than 7,000 local residents across the region.
