DOCSIS 3.0

 

Wideband Comes to Washington

Tuesday, June 9th, 2009

It’s been more than a year now since I first mentioned deployment of wideband Internet access based on the DOCSIS 3.0 standard. With the use of channel bonding, cable operators are able to offer speeds exceeding 100 Mbps downstream.

The first launch was in the Twin Cities market in April of 2008. Since then, it’s been popping up all over America: Baltimore, Atlanta, Chicago, St. Louis, Boston, Philadelphia, Seattle, Portland, Indiana, New Hampshire, New Jersey, New York.

Now, Washington, DC will also be benefiting from more robust bandwidth. In May, Cox deployed its Ultimate Internet service to residential and business customers in Northern Virginia. Today, Comcast announced that its Extreme 50 service will be launched in the DC Metro area. The service is first being offered in the Anacostia neighborhood, with the entire area expected to have wideband by year’s end. Most existing high-speed Internet customers will see their speeds double for no additional cost.

Now that cable is the broadband leader in Our Nation’s Capitol, you can look for continued wideband deployment by operators all over the country. Stay tuned!

Verizon and Parlor Tricks

Friday, May 1st, 2009

Earlier this week, Cablevision announced Optimum Online Ultra, a new high-speed Internet product that uses the DOCSIS 3.0 standard to deliver speeds up to 101 Mbps. This is very exciting news, especially when you connect this announcement to the cable operators who have deployed wideband service over the past year – Comcast, Charter and Cox – and those that are planning to deploy in 2009.

And that might be all there is to say about it, but there was a little twist. Our friends over at Verizon seemed really unhappy about the launch. Was it the 101 Mbps that bothered them or the $99 monthly price? At any rate, take a look at this odd post on the Verizon Policy blog.

Besides arguing against the business model for their own FiOS deployment, you’ll note that one of their key complaints is that Cablevision’s 101 Mbps is a “parlor trick” because “there is little evidence of market demand for the speed.” This echoes a PCMag.com argument (referenced in this blog post) that higher speeds are unnecessary: “…no average consumer is going to pony up almost $100 for home broadband service—regardless of speed.”

Now, I’m a little confused here. I seem to remember all these arguments over the past couple years (sarcasm alert) about how horrible it was that consumers in Europe and Asia had so much more bandwidth, while we Americans had to struggle along with our anemic speeds. And now we’re told, “Bah, who really needs that much bandwidth?”

Secondly, Verizon pulls out the long-disproven accusation that cable broadband service is shared bandwidth and so it’s not real. Well, I hate to break it to the fine folks at Verizon, but all bandwidth is shared at some point, even at FiOS. Yes, cable broadband is engineered differently than FiOS is. Cable started deploying modem service about 15 years ago and the intention was always that customers would share bandwidth off a node, but that nodes could be split as needs increased.

Verizon issues a clarion call against “parlor tricks.” Here’s a neat trick for you: If you’re a FiOS customer, with its “all-fiber” service, take a look at the back of your TV or at your modem. You’ll find a piece of coaxial cable, making it a hybrid fiber-coax system. So, wasn’t “fiber optics right to the door, true QAM” a bit of marketing? Especially in light of the fact that cable has generally built its broadband customer base and high penetrations while offering its best services and fastest speeds to the homes passed by its network, while Verizon focuses attention on FiOS’ fast speeds but still offers copper-based DSL service across most of its footprint.

Add the fact that Verizon says that Cablevision “claims” they deployed the service across their footprint (when a Cablevision spokesman confirmed that the service will be available across their service area on May 11) and you get the idea.

But this is competition in action. When Verizon thought they had the edge, they bragged pretty loudly. Some blogs, such as GigaOM and CrunchGear, noted that Verizon seems to be protesting a little too much this time.

Verizon Challenges DOCSIS 3.0 – They’re Wrong, So Wrong

Tuesday, February 3rd, 2009

It’s no surprise that cable operators face competition. That’s a good thing. As we wrote in our 2008 Industry Overview:

Competition is the lifeblood of a successful and thriving marketplace, and the cable industry faces stiff competition across all the markets it serves. The consumer is the beneficiary, enjoying more choice, greater convenience and better value than ever before.

Other companies come out with new products and services and we do likewise. But it may be that Verizon is feeling the heat a bit. I’m assuming that’s why they felt the need last week to launch an attack on the cable industry’s new DOCSIS 3.0 specification, which enables wideband Internet access.

Last year, we tracked Comcast’s deployment of DOCSIS 3.0 in a number of markets. Last week, Charter Communications joined in with the launch of its Ultra60 service. Later that same day, on Verizon’s PolicyBlog, came this post: Behind Cable’s DOCSIS 3.0 Broadband Claims. Let’s break down Verizon’s arguments.

Verizon correctly note that DOCSIS 3.0 equipment employs channel bonding to deliver faster speeds (Comcast’s Extreme 50 offers 50 Mbps downstream; Charter’s Ultra60 is 60 Mbps), but also has the potential to deliver hundreds of megabits per second. Verizon leaves out the context that cable has been migrating towards an all-digital environment for years (Here is one typical post explaining the transition). They also assert that channels for use in DOCSIS 3.0 services will come exclusively by moving basic analog tier channels to digital. That is incorrect, since it ignores the use of switched digital video which allows cable operators to reclaim bandwidth in the digital tier.

Citing many analyses – yet linking only to a report prepared by the Fiber to the Home Council (hardly an unbiased source) – Verizon states that higher speeds on cable will decrease the customer experience and will require cable to upgrade.

In fact, the cable hybrid fiber-coax plant offers a great deal of capacity and flexibility in how nodes are combined to provide optimal service levels based on subscriber penetration and demand. But also unstated is the fact that FiOS also multiplexes (or combines the signals) to customers onto a shared trunk — they just do so in a different portion of their network.  In other words, even though the link to customers might be very fast, there is still a choke point where customers have to compete for bandwidth.  Too many customers trying to access the Internet at the same time can have the same effect on a FiOS network as it could on a DOCSIS network. Funnily enough, the blog post makes it sound as if Verizon doesn’t have to employ any network management at all!

Verizon makes a broad assumption regarding cable operator deployment plans for DOCSIS 3.0 services, somehow minimizing the technology because it is just now being deployed, and citing “indicators” that it won’t be deployed to all customers.

I’m not sure what tea leaves were used to make that assertion.

Comcast has been quite public in indicating it had DOCSIS 3.0 services in front of 10 million homes and businesses at the end of 2008 and plans to have it in front of all the homes and businesses it passes with plant capable of delivering 3.0 service in 2010. That’s just one cable operator out of the dozens that now have plant capable of running DOCSIS 3.0 services. Those operators pass more than 90% of residences in the United States. And DOCSIS 3.0 service has been operating quite successfully outside the US for some time now, with deployments in Japan and Singapore.

All of Verizon’s arguments ignore the huge capital expense that Verizon has made and continues to make to ultimately serve a portion (50%) of its footprint; specifically, Verizon is spending $23 billion to reach 13% of US households. In fact, they are still conspicuously avoiding neighborhoods and whole cities, as this Baltimore columnist notes. The rest of Verizon’s footprint will be relegated to DSL service, which is rapidly losing market share.

In contrast, cable’s investment to deploy DOCSIS 3.0 is modest.  And with the channel bonding that DOCSIS 3.0 permits, network speeds of 100 Mbps, 160 Mbps, and even higher will be possible.  In fact, a 750 MHz cable plant (90% of the country’s cable network miles) has a digital equivalent capacity of approximately 5 Gbps of bandwidth.

Bottom line: The cable industry feels good about the services we’re launching these days. Competition has been pretty good for us; take a look at the growth rates for cable’s phone service. I’ve seen Verizon representatives claim the company’s network is built for “decades to come” and is “future-proof.” We believe in continually getting bigger, better, faster. We believe in delivering more value over time.  I think this will be a good fight, and one that consumers will enjoy.

End-of-year DOCSIS 3.0 deployments

Friday, December 12th, 2008

Comcast has announced it will be deploying the new DOCSIS 3.0 wideband standard in more areas: the Baltimore market, including areas in Anne Arundel County, Annapolis and Howard County (where I live); Atlanta’s North Fulton County; and Chicago’s northern and northwestern suburbs, including northern Cook County, Lake County, McHenry County and the northern edge of Kane County.

Those deployments will actually be expanded soon, reaching the city of Chicago, western and southern Chicago suburbs, northwestern Indiana, additional Atlanta communities, and the remainder of the Baltimore region in the first half of 2009.

All of this follow previous deployments earlier this year in the Twin Cities (April); Boston Metro and parts of southern New Hampshire, Philly Metro, and New Jersey (October); and Seattle, Portland, Spokane, Eugene (November).  If you’ve been reading this blog, you could have followed the progress here to here to here to here to… Well, here we are in December.

By the end of 2008, about 10 million homes and businesses will be able to sign up for wideband service. Customers can enter their zip codes at www.comcast.com/fastestfast to find out if they live in a serviceable area.

DOCSIS 3.0 Hits the Pacific Northwest

Monday, November 17th, 2008

Less than a month ago, I wrote about Comcast’s deployment of DOCSIS 3.0 in New England and areas of Philadelphia and New Jersey, following up on the Minneapolis/St. Paul market. I mentioned that they expected to reach more than 10 major markets in the coming months.

Here we go: Comcast launches DOCSIS 3.0 in Oregon and Southwest Washington, including such communities as Aberdeen, Spokane, Beaverton, and Eugene. The Extreme 50 tier offers download speeds of up to 50 Mbps. Comcast will also double speeds for the majority of existing high-speed Internet customers at no additional cost.

The company has a web page which allows you to check if wideband is available in your area or to sign up for e-mail updates when it is rolled out to you.
