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.

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.

Rogers Communications has slightly bumped the monthly usage allowance for its “Lite” Internet plan up by 5GB per month to 20GB. The company also doubled the speed of the entry-level package from 3Mbps to 6Mbps. Upload speed remains at 256kbps.

But the plan still carries a hefty price — $38.49 a month, and there is a stiff $4/GB overlimit fee for those who exceed their allowance. Just south of Lake Ontario, Time Warner Cable’s “special offer” provides cap-free 10/1Mbps broadband for $29.99 a month for a year.

Our regular reader Alex mocks the move as another example of Canadian competition at work for consumers. Rogers has made only small adjustments to their usage caps since last summer, and customers who want the most generous usage allowances (paltry when compared to western Canadian ISPs), have to spend money out of pocket to upgrade to DOCSIS 3 technology.

As of today, here is the current roundup of Internet plans from Rogers

Frontier Communications’ DSL service to some residents in Sardinia, Ohio has been progressively slowing down to the point Speedtest.net rated one man’s connection an “F-Minus.”

Larry Meeker’s broadband service from Frontier achieved speeds of just 190kbps — about four as fast as traditional dial-up Internet service.  Upload speeds reached just 1kbps.  When Meeker called Frontier Communications to complain about the lousy broadband speeds, he reports Frontier didn’t seem in any hurry to improve his service.

WKRC-TV TroubleShooter Howard Ain reports Frontier had done little for Meeker initially, saying “it will cost a lot of money for the company to upgrade” the broadband facilities in inherited from an acquisition from Verizon Communications.

Frontier changed its mind when Ain indicated the company’s broadband woes were about to be a feature item on WKRC’s 6pm local news.  Meeker also told the station he was preparing to file a complaint with Ohio’s public utility regulator.  Just a few days before the report aired, Frontier called Meeker to tell him improved service was on the way.

Meeker reports it used to take 10-15 seconds to load even basic web pages over Frontier’s DSL service.  But after the company began work on Meeker’s connection, pages are loading much faster, usually after 1-3 seconds.

The Sardinia man noted the best way to get action out of Frontier might be to call the media to get the company to do the right thing.

“I’m very happy that it is so easy to contact Channel 12 news and Howard Ain and know that somebody is at least going to call you and if there is a problem they are going to check it out and investigate it,” Meeker told the station.

A spokesman for Frontier Communications blamed the old owner — Verizon Communications, for inadequate broadband facilities in place to serve Sardinia and surrounding areas. The company says it is spending $90 million on upgrades because people are using the Internet a lot more in the area.  New circuits bringing additional capacity are anticipated to begin service by the second week of February.

North America’s broadband rankings continue to take a beating at the expense of countries deploying fiber optic broadband.  While the United States and Canada cope with aging landline technology and an uncompetitive marketplace that tells consumers they don’t need fiber-fast broadband speed, countries like Bulgaria, Lithuania and Estonia are lighting up 50-100Mbps networks that often charge lower prices than North Americans pay for 1-3Mbps DSL.

Ookla, a global leader in broadband testing and web-based network diagnostic applications, reports that the best performing broadband networks for speed, value, and performance are increasingly in Europe and Asia.  While both the United States and Canada used to be among the world leaders in broadband infrastructure, that is no longer true.

Some examples:

• The United States now scores 31st in average download speed, Canada is 33rd;
• In upload speed, America now ranks 37th, Canada a woeful 69th;
• Ookla’s Household Quality Index, which ranks packet loss and general reliability of home connections found Canada scoring 27th place, the United States 38th;
• At a cost per megabit, neither the US or Canada offers very good value.  The USA ranked 29th ($4.95 per megabit), Canada 33rd ($5.85 per megabit);
• Neither country does a great job delivering the speeds and service promised either.  The USA ranked 25th, Canada 32nd.

Ookla found that while speeds are rising in North America, they are not increasing nearly as fast as in other, higher-ranked countries.  Most of the speed gains in North America come from cable or limited fiber-broadband deployments like Verizon FiOS or community-owned fiber to the home networks.  Wireline ADSL service, which represented a larger proportion of home Internet connections in 2008, continues to lose ground to faster options from cable companies, community-owned broadband, and phone company fiber upgrades.  In eastern Europe, the Baltics, Russia and Ukraine, many of the dramatic boosts in broadband speed and quality come as a result of national fiber network upgrade projects.

While speeds in North America are gradually increasing, both the U.S. and Canada are being outpaced by many countries in Europe and Asia.

While providers in the United States and Canada often dismiss fiber as too costly, Ookla found fiber-based networks delivering some of the world’s best values in broadband.

For example, on a cost-per-megabit basis, Bulgaria’s new fiber networks deliver the world’s cheapest Internet service, at an average of just $0.64 per megabit.  The average broadband speeds in the country are now higher than 21/11Mbps.

Elion headquarters in Tallinn. Elion delivers fiber broadband to homes across Estonia.

Contrast that with average speeds in the United States (12.41/2.97Mbps) and Canada (11.95/1.70Mbps).  Other top scoring countries for cost-per-megabit include:

• Romania $0.97 USD
• Lithuania $1.11 USD
• Ukraine $1.17 USD
• Republic of Moldova $1.41 USD
• Latvia $1.80 USD
• Hungary $2.00 USD
• Slovakia $2.04 USD
• Hong Kong $2.26 USD
• Russia $2.51 USD

In terms of download speed, Estonia’s investment in a national fiber network is now paying dividends, with a dramatic increase in national average broadband speeds to 50/28Mbps.  As new cities join Estonia’s fiber network, speeds take a dramatic upswing.  Contrast average speeds in Saue (101.03Mbps), Viimsi (98.98Mbps), Tallinn (69.80Mbps), and Võru (65.58Mbps) with ADSL-rich Pärnu (12.55Mbps), Paide (12.40Mbps), Rapla (8.93Mbps), and Valga (7.71Mbps).

It is much the same story in other fiber-rich countries, where broadband speeds far exceed the averages in the United States and Canada:

Look what happens to Estonia's broadband speed rankings when it switched on its national fiber broadband network.

• Lithuania 31.65 Mbps
• South Korea 31.44 Mbps
• Latvia 25.42 Mbps
• Sweden 24.62 Mbps
• Romania 24.47 Mbps
• Netherlands 24.36 Mbps
• Singapore 22.94 Mbps
• Bulgaria 21.12 Mbps
• Iceland 20.53 Mbps

Despite all of the bad news, the cable industry’s trade publication Multichannel News tried to find victory in the jaws of defeat, noting things could be worse… if they ran traditional phone companies.

Cable operators delivered the fastest average broadband download speeds in 2011 — with major MSOs easily blasting by rival telco and satellite Internet services — according to data from independent testing firm Ookla.

For the full year, the six fastest residential Internet service providers in the U.S. based on average download speed were Comcast, Charter Communications, Cablevision Systems, Time Warner Cable and Insight Communications.

[…] Comcast and Charter delivered average download speeds of 17.19 Megabits per second, followed by Cablevision at 16.40 Mbps, Cox at 15.76 Mbps, TWC at 14.41 Mbps and Insight at 14.22 Mbps.

Verizon Communications fared better than its telco peers with an average download speed of 12.94 Mbps, thanks to FiOS Internet, its fiber-to-the-home service that provides up to 150 Mbps downstream. And overall, Verizon had the highest upstream speeds with an average of 7.41 Mbps. Still, the company’s legacy DSL services dragged down overall speeds.

Behind DSL were woefully slower speeds from the nation’s wireless ISPs (which include 3G broadband from large companies like Verizon Wireless and AT&T), and perennially last place satellite Internet.

Moffett

Despite repeated claims by providers that consumers don’t need fiber-fast broadband speeds, industry analyst Craig Moffett at Sanford Bernstein tells a different story:

“Technology adoption is creating a feedback loop that increasingly favors cable’s physical infrastructure,” Moffett wrote in a research note last month. “As more people are served by higher-speed connections, more and more applications are evolving to take advantage of them. Customers with lower-speed connections are increasingly being forced to upgrade to higher speed connections… or be left behind.”

The conclusion reached by Multichannel News columnist Todd Spangler:

“The relative broadband speeds of cable vs. telco isn’t merely an academic curiosity: Major providers are increasingly touting Internet performance in their marketing as they fight for consumers’ dollars.”

Unfortunately for the cable industry, although DOCSIS 3 upgrades have afforded dramatic increases in broadband download speeds, upload speeds lag behind.  Fiber to the home networks are best positioned to achieve victory in the global broadband race.  That is important not only because it delivers consumer dollars to the best provider in town, but fuels the further development of the digital, knowledge-based economy North America increasingly seeks to lead.
