Last month, Comcast rolled out its DOCSIS 3.0 service in more areas of California, including Chico, Grass Valley, Marysville, Orland, Oroville and Yuba City (see complete list of cities and communities below).

“Wideband utilizes our existing fiber-optic network in neighborhoods across our footprint. With this next generation of service, our customers’ online experience is dramatically enhanced,” said DeeDee Brady, general manager of Comcast’s North Valley Area . “And this is just the beginning. Wideband, combined with our fiber-optic network, gives us the capability of meeting the needs of our customers for many years to come by offering even faster speeds in the future.”

The new tiers are available to residential homes and businesses in the following cities and areas: Beale AFB, Biggs, Butte County, Chico, Colusa, Corning, Durham, Grass Valley, Gridley, Hamilton City, Lake Wildwood, Linda, Live Oaks, Magalia, Marysville, Nevada City, Nevada County, Olivehurst, Orland, Oroville, Palermo, Paradise, Penn Valley, Sutter, Wheatland, Willows and Yuba City.

Comcast’s DOCSIS 3.0 tiers are Extreme 50 and Ultra. Extreme features download speeds of up to 50 Mbps and upstream speeds of 10 Mbps for $99.95 per month with a subscription to Comcast’s video or voice services. Ultra has a downstream speed of 22 Mbps down and 5 Mbps up at a cost of $62.95 per month when paired with the company’s video or voice offerings.

Business customers will also have access to the new wideband services. Customers can sign up for the Deluxe 50 Mbps/10 Mbps tier for $189.95 per month, while the Premium tier has speeds of 22 Mbps/5 Mbps for $99.95.

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