Even as DOCSIS 3 cable technology continues to roll-out across cable systems now offering faster Internet speeds, the next generation of cable broadband is on the way, reportedly capable of delivering up to 10/2Gbps service.

CableLabs’ DOCSIS 3.1 project will be the subject of a special panel at an upcoming cable engineer conference later this month.

“DOCSIS 3.1 specification development is a significant milestone on the industry’s road map to next-generation services,” said CableLabs chief technology officer Ralph Brown. “Our SCTE Cable-Tec Expo panel will identify the motivations, requirements and key technology building blocks under development with the collaboration of the vendor community.  DOCSIS 3.1 solutions will provide both residential and commercial cable customers with faster data rates — both upstream and downstream — that support increasingly compelling broadband services.”

The DOCSIS 3 standard allows cable operators to bond multiple channels to support faster speeds.

The new standard will incorporate changes in how cable spectrum is utilized for broadband, vastly expanding potential bandwidth. Although the standard can support gigabit broadband speeds, nobody expects cable companies to offer those speeds in the near term.

Instead, providers are more interested in addressing their upstream speed limitations. From the earliest days of cable broadband, the assumption was that customers would care far more about downstream speeds and consider uploading an afterthought. The result was a network that prioritized download speed. But as users continue to upload more multimedia content and embrace cloud storage, slow upload speeds are starting to aggravate customers.

DOCSIS 3.1 is rumored to de-emphasize the current QAM modulation cable operators use for broadband in favor of more robust technologies such as orthogonal frequency-division multiplexing (OFDM), already used by the wireless industry. Unlike interference/noise-prone QAM, OFDM uses much smaller subcarriers that work better in noisy signal conditions. Although coaxial cable is capable of delivering a large amount of spectrum to cable operators, all of it cannot be practically used because of external interference from electrical equipment, broadcast radio and television signals, and other sources. Error-correcting technologies can let operators use more of their available spectrum without reducing the quality of service to customers.

The study group working on DOCSIS 3.1 is also reviewing the incorporation of “low density parity-check” (LDPC) error correction that would efficiently improve noise rejection over today’s Reed-Solomon approach. Combining OFDM and LDPC could improve spectral efficiency up to 25 percent.

The cable industry is pressuring the study group to preserve backwards compatibility with the older DOCSIS 3.0 standard just now coming into widespread use. Some industry insiders predict cable operators will keep today’s QAM modulation for downstream speeds while boosting upstream speeds using OFDM.

Cable operators across the country are gradually moving away from analog service in favor of digital with the ultimate goal of an entirely IP-based network for television, phone, and broadband. The pressure is on for DOCSIS 3.1 to help accelerate that transformation, but most industry experts don’t believe the new standard will be finalized until at least the middle of 2013, with at least 6-12 months before equipment shows up supporting the finalized standard.

Suddenlink is throwing a hissyfit over Frontier’s aggressive advertising.

Now come on, you are both pretty… slow that is.

Suddenlink Communications is crawling mad that Frontier Communications has been hammering the cable company over their broadband speeds, which PC Magazine this week proclaimed were nothing to write home about. The cable operator successfully challenged some of Frontier’s ads with the National Advertising Division of the Council of Better Business Bureaus.

The group recommended Frontier cease making claims that its DSL service offers “dedicated” lines to the Internet in contrast to Suddenlink, which forces customers to share their connection with the whole neighborhood.

Frontier claims Suddenlink’s network can bog down during peak hours, while Frontier makes sure customers consistently get the speeds they pay for.

Many of the ads targeted customers in West Virginia, who regularly tell Stop the Cap! neither provider competing there offers particularly good service.

“Is Frontier kidding?,” says Shane Foster, a former Frontier customer in West Virginia. “I was supposed to be getting up to 6Mbps service and I was lucky to get 1.5Mbps at 2 am.”

Foster says he believes Frontier oversold its DSL network in his area, with speeds slowing even further during the evening and weekends when everyone got online. While Frontier may not require customers to share a line from their home to the company’s central office, congestion can occur within Frontier’s local exchange or on the connection Frontier maintains with Internet backbone providers.

“The technician sent to my house even privately admitted it,” Foster tells Stop the Cap!

Foster switched to Suddenlink, but he is not exactly a happy customer there either.

“Their usage caps suck, the service is slow, and their measurement tool is always broken,” Foster shares. “West Virginia doesn’t just get the bottom of the barrel, it gets the dirt underneath it.”

Frontier Communications says it has been making improvements in West Virginia and other states where it provides DSL broadband. Some areas can now subscribe to 25Mbps service because of network upgrades. Foster says he would dump Suddenlink and go back to Frontier, if they can deliver speeds the rest of the country gets.

“Sorry, but 1.5Mbps is not broadband and with their prices, tricky fees and contracts it is robbery,” says Foster. “They need to clean up their act and I’ll come back. I hate usage caps with a passion.”

Frontier says it will appeal the NAD’s decision. But Frontier might do better advertising its broadband service as usage cap free — something customers consistently value over those running Internet Overcharging schemes.

PC Magazine has declared fiber to the home service America’s fastest broadband technology, and among larger providers, Verizon’s FiOS once again took top honors for delivering the fastest and most consistent broadband speeds.

Over the past nine months, the magazine’s readers have been conducting regular speed tests using their personal broadband connections. The magazine found fiber optics remains the best current technology for delivering cutting-edge broadband service, with an average speed rating for FiOS reaching 29.4/16.7Mbps. Since PC Magazine readers were subscribed to various speed tiers while conducting the tests, the magazine’s ratings do not measure the fastest possible speeds on offer from different providers. Verizon’s most-popular service bundle includes 15/5Mbps service, heavily weighting Verizon’s speed rating which is capable of even faster speeds with their 50-300Mbps premium service tiers. But on average, consistently fast speeds kept them in the top spot.

Cable broadband technology was the second-best choice, depending on how cable operators implement it. Cable companies depend on a singl, shared broadband pipeline in each neighborhood. DOCSIS 3 upgrades allow a cable operator to vastly expand that pipeline by “bonding” several channels together to increase the maximum bandwidth. Cable operators that combine the latest technology with the smallest number of customers sharing a connection do the best.

Midcontinent Communications (better known by customers as Midco), achieved first place nationwide. The company, which serves customers in Minnesota, the Dakotas, and Wisconsin, took top honors with an average speed of 24.7/4.4Mbps — the best of any cable operator.

Ratings sometimes show the level of investment made by cable operators in their network. A sudden boost in average speeds is a sure sign a cable operator is rolling out network upgrades. A speed decline can expose a cable company trying to oversell an already constrained network. Charter Cable, which has routinely gotten poor ratings in Consumer Reports’ rankings, showed dramatic improvement in PC Magazine’s ratings, achieving third place with an average speed increase from 15Mbps to 18.5Mbps. But while the added speed is nice, the company’s usage caps are not. Conversely, WOW!, which achieved top scores in Consumer Reports’ ratings, scored towards the bottom of PC Magazine’s tests.

Comcast, which last year trumpeted its high rankings in controversial ads claiming to deliver the fastest broadband in the nation has now been overrun by both Midco and Charter. Comcast Xfinity is now in sixth place, hardly the fodder for any future ad campaign.

Cox Cable actually lost ground since last year, with average speed now down to 14.8Mbps. The bottom four: Time Warner Cable, Mediacom, WOW!, and Suddenlink — are all hampered by slow upload speeds and more anemic “take-rates” on higher speed broadband plans with the speeds on offer. With fewer premium speed customers, average speed ratings take a hit from the larger proportion of customers sticking with standard service.

Phone companies barely appeared in the magazine’s top ratings. AT&T’s U-verse could not even make the top-15. While 25Mbps was adequate when U-verse was first deployed, the broadband speed race has quickly overshadowed the company’s fiber to the neighborhood service, which still relies on home phone lines and antiquated copper infrastructure in the immediate neighborhood.

Phone companies still offering traditional ADSL on almost all-copper networks turned in even more dismal results — most too low to rate. Only Frontier’s adopted FiOS network kept them in the rankings in the overall broadband “slow zone” in the Pacific Northwest, along with CenturyLink’s acquired ADSL2+ and bonded DSL networks built by Qwest.

ISPs that perform poorly typically criticize the methodology of voluntary speed tests as the basis for speed and performance ranking. Most criticize the apparent lack of consistency, random sampling, the possibility rankings may be weighted in certain geographic areas, and may mix a disproportionate number of customers with standard or premium level speeds to unfairly boost or diminish average speed rankings. But overall, PC Magazine’s rankings show some technologies superior to others. If a customer has a choice, finding a fiber to the home provider is likely to provide an improvement over what the cable company offers, but the differences between phone company DSL and cable broadband are even starker.

Phillip “Tollbooths are not innovation” Dampier

Federal Communications Commission chairman Julius Genachowski last week wrote a guest editorial on TechCrunch espousing the benefits of faster broadband networks, but the advances he celebrates often come with innovation-killing usage caps and overlimit fees he continues to ignore.

We feel the need – the need for speed. As Tom Friedman and others have written, in this flat global economy a strategic bandwidth advantage will help keep the U.S. as the home and most desired destination for the world’s greatest innovators and entrepreneurs.

[…] But progress isn’t victory, particularly in this fast-moving sector. Challenges to U.S. leadership are real. This is a time to press harder on the gas pedal, not let up. The first challenge is the need for faster and more accessible broadband networks. We need to keep pushing because our global competitors aren’t slowing down. I’ve met with senior government officials and business leaders from every continent, and every one of them is focused on the broadband opportunity. If we in the U.S. don’t foster major investments to extend and expand our broadband infrastructure, somebody else will take the lead.

We need to keep pushing because innovators need next-generation bandwidth for next-generation innovations – genetic sequencing for cancer patients, immersive and creative software to help children learn, ways for small businesses to take advantage of Big Data, and speed- and capacity-heavy innovations we can’t yet imagine.

We need to remove bandwidth as a constraint on our innovators and entrepreneurs. In addition to steadily increasing broadband speed and capacity for consumers and businesses throughout the country, we need – as we said in our National Broadband Plan – “innovation hubs” with super-fast broadband, with speed measured in gigabits, not megabits.

[…]Some argue the private sector will solve these challenges itself, and that all government has to do is get out of the way. I disagree. The private sector must take the lead, but the public sector has a vital though limited role to play.

Among the policy levers government needs to use is the removal of barriers to broadband buildout, lowering the costs of infrastructure deployment with new policies like “Dig Once” that says you should lay fiber when you dig up roads. The President recently issued an Executive Order implementing this idea, suggested in our Broadband Plan. Government must promote competition, which drives innovation and network upgrades.

We must ensure the Internet remains an open platform that continues to enable innovation without permission.

Genachowski

Genachowski’s vision for faster broadband has the noble goal of maintaining competitiveness with the rest of the world and putting the United States back on top in broadband rankings and innovation. But while hobnobbing with his industry friends at recent industry conventions, he may have gotten too close to one of the biggest impediments holding us back — big cable and phone companies merrily working their magic to create a comfortable duopoly with pricing and service plans to match.

Back in the late 1990s, most cable operators thought of broadband as an ancillary service easy enough to operate, but probably hard to monetize. Just like digital cable radio services like Music Choice and DMX, “broadband” would likely appeal only to a tiny subset of customers.

“Back in the 1990s, Time Warner was primarily a TV company in a TV industry.  Broadband then was an innovating and radical thing, and a lot of people thought it was stupid and wouldn’t work,” Time Warner Cable CEO Glenn Britt said in April, 2009.

The launch of “Road Runner” was not the most auspicious marketing effort undertaken by the cable operator. In fact, the service was rarely targeted for price adjustments, hovering at around $40 a month for a decade.

When the Great Recession hit the United States, something unexpected happened. Cable operators discovered people were willing to cancel their cable and phone services, but not their broadband. In fact, as high bandwidth online video became an increasing part of our lives, the cable industry realized they were in the catbird seat to deliver the best broadband experience, and be well-paid for it. With little competition, increasing prices brought little risk and, thanks to the insatiable drive to boost revenue and reduce costs, implementing usage caps to control “excess” usage and costs were within their grasp.

In 2008, when Stop the Cap! launched, only a handful of ISPs had usage caps. Now most providers, with the exception of Time Warner Cable, Verizon, Cablevision, and a handful of others, all have usage allowances and overlimit fee Internet Overcharging schemes to further pad their bottom lines.

Innovation: Rationing Your Internet Experience — Stick to e-mail and web pages.

Genachowski has completely ignored the growing pervasiveness of usage caps, and even excused them as an experiment in marketplace innovation. But limits on broadband usage will also limit the broadband innovation revolution he wants, especially when most Americans have just one or two realistic choices for broadband service:

1. Usage caps are the product of artificial scarcity. Rationing Internet usage, even with now-pervasive cost-effective upgrades like DOCSIS 3, simply does not make sense (but it will make dollars). Cable operators are switching off analog television service to free up bandwidth to provider faster Internet speed and fatten the pipeline that delivers it. They have plenty of capacity, but continue to proclaim they must limit usage for “fairness” reasons, without providing a single shred of evidence to prove the need for usage caps. Consumers will self-ration just to avoid the prospect of being cut off or handed a bill with overlimit fees.
2. Usage caps make faster speeds irrelevant. Selling customers premium-priced, super fast broadband speed is hardly compelling when accompanied by usage caps that constrain the benefits of buying. Why pay $20-50 more for faster speeds when customers cannot take practical advantage of them. Customers using their Internet service to browse web pages and read e-mail have no interest in upgrading to 30+Mbps. Customers streaming video or moving large files do.
3. Usage caps retard innovation. Google’s new 1Gbps fiber optic network was built on the premise that usage caps were unnecessary on a fiber-based network and would retard innovation. Developing the next generation of innovative apps that Genachowski celebrates will never happen if developers are discouraged by Internet usage toll booths and stop signs. The cost to provide the service is not largely dependent on customer usage. It is the initial price of last mile infrastructure that really matters. Both cable and phone companies have reduced their investments to upgrade their networks, and AT&T and Verizon both contemplate getting rid of their rural landlines. Most cable operators paid off their networks years ago.
4. Usage caps create a whole new digital divide.  Time Warner Cable’s discounted Internet Essentials program delivers only a $5 discount with a harsh 5GB usage cap. For an income-challenged home compelled to switch to a provider’s budget plan, the result is a different Internet experience than the rest of us enjoy. Imagine if your home broadband account was limited to 5GB a month. What online services would you have to avoid to stay under the provider’s limit? Traditionally, operators sell the lowest speed tiers with the lowest usage allowances. Slower speeds already offer a disincentive to use high bandwidth services, but many providers typically drive that disincentive home even harder with a paltry allowance that will cost plenty to exceed.
5. Usage caps harm our broadband standing. While Genachowski celebrates increasing broadband speeds, he ignores the fact the rest of the world is moving away from usage caps even as the United States moves towards them. Both Australia and New Zealand elected to construct their own national fiber networks in large part because the heavily usage-capped experience was holding both countries back. Usage caps are a product of a barely competitive market.

Tech News Today debunks providers’ claims that usage caps are fair and control those who “overuse” their networks, noting the same phone companies (AT&T) pushing for usage caps are also moving voice calling to unlimited service plans. (August, 2011) (4 minutes)

Time Warner Cable has lost between 10-15 percent of their analog cable television customers over the past year, according to Time Warner Cable president and chief operating officer Rob Marcus.

Speaking at this morning’s Goldman Sachs Communacopia Conference, Marcus noted the economic downturn has continued to cost the cable operator “single play” subscribers. Marcus noted that roughly 60 percent of the cable company’s customers are now on discounted or retention plans, and the company has no plans to reduce aggressive retention offers and promotions in the immediate future. Time Warner Cable will also exercise caution when customer promotions expire, an allusion to the company’s practice of gradually resetting rates to retail prices over an extended period of time to avoid antagonizing customers into switching providers.

Marcus acknowledged broadband is now a key service for Time Warner Cable, one that the company will continue to exploit to drive earnings. Some investors have complained Time Warner has only managed an increase of 2-3 percent in Average Revenue Per User (ARPU) for broadband, a key metric for Wall Street. Marcus was asked why Time Warner, with its superior market share over telephone companies, was not “exercising the price lever a little bit more” in a marketplace lacking serious competition.

“I think it is fair to say that as the utility of the [broadband] product increases in customers’ minds, their willingness to pay for it (assuming they are able) goes up, so I think it stands to reason that we can continue to increase rates on high speed data,” Marcus said.

But even more important to Time Warner Cable is its differentiated broadband speed tiers, which the company is refining to pick up additional revenue and price-resistant customers. Broadband usage caps will be a part of that equation.

Marcus confirmed that Time Warner Cable will provide unlimited broadband packages to its premium tier customers, but will introduce usage-limited service on its budget tiers. Currently, the company only imposes a usage cap of 5GB on its Internet Essentials package, which offers a $5 discount off regular prices. But Marcus seemed to acknowledge that the company plans to experiment further with additional limits.

“We are going to deliver very fast speeds, unlimited consumption, and now mobile capability via our Wi-Fi network to those customers who demand it and are willing to pay premium prices for those tiers of service,” Marcus said. “At the other end of the spectrum we are going to have budget products as we do today that offer lower speeds, more limited consumption like our Internet Essentials product, and those probably won’t have access to our Wi-Fi hotspots. We think that is the best way to drive revenue and profitability.”

Marcus also told investors the company was working on the next generation of the company’s electronic program guide, which he said will be cloud-based. Time Warner Cable continues to signal it is willing to work with third party set top box manufacturers to let customers dump traditional set top boxes, but only so long as Time Warner Cable gets the credit in the minds of customers. The company is also working on rolling out video-on-demand for its online video apps.
