Just a few years after cable systems began upgrading to DOCSIS 3.0 to improve broadband speeds and performance through channel bonding, CableLabs is set to formalize next-generation DOCSIS 3.1 by the end of this month, allowing cable broadband speeds to reach well into the gigabits.

“We made a fairly bold assertion in October of last year that we would have them substantially complete and publicly issued by the end of 2013,” Matt Schmitt, director of DOCSIS at CableLabs said this morning. “This is quite a bit faster than we have ever pulled off before. It’s not a small project to do a new DOCSIS with a new physical layer underneath. It was an industry-wide effort and I tell you what, they’ve been busting their tails.”

Schmitt discussed the new standard at the DOCSIS 3.1 Engineering Pre-conference Symposium held in Atlanta.

The new standard for cable broadband was designed to protect the industry from competing technologies — notably fiber to the home service which offers immediate gigabit broadband capacity. DOCSIS 3.1 was designed to support up to 10/1Gbps speeds using larger spectrum bands cable operators are opening for data services after switching off analog cable television channels.

Cable operators are not expected to offer gigabit broadband service in most areas. Many operators still dedicate the largest amount of their available bandwidth to analog cable television channels. But DOCSIS 3.1 provides scalability as operators move towards digital television delivery. It also offers 50 percent more data capacity over DOCSIS 3.0 over the same spectrum.

DOCSIS 3.1 uses a new modulation scheme coupled with more robust forward error correction (FEC) to improve efficiency and performance. The new standard dumps Reed-Solomon FEC in favor of low-density parity check (LDPC) technology. DOCSIS 3.1 relies on orthogonal frequency division multiplexing (OFDM), also used by wireless carriers to boost performance over limited spectrum.

Despite the new standard, DOCSIS 3.1 will be fully backwards-compatible with DOCSIS 3.0, which means customers buying their own cable modems will not find them obsolete anytime soon. When a customer decides they want faster broadband speeds, the cable operator can advise if a new DOCSIS 3.1 modem is needed. In most cases, it will not.

Most cable operators are expected to take at least a year lab testing the new technology and waiting for vendors to incorporate support for DOCSIS 3.1 in future generations of cable broadband equipment.

Comcast, one of the more speed-aggressive cable operators likely to be an early adopter of DOCSIS 3.1, indicated it would probably be 2015 before customers can buy DOCSIS 3.1-powered products. But Comcast will begin trials next year, according to Jorge Salinger, vice president of access architecture.

Time Warner Cable plans to use the next generation of DOCSIS as they migrate from conventional MPEG-based video delivery to IP video transport on a Converged Cable Access Platform (CCAP). But Time Warner Cable customers don’t usually get the fastest possible broadband speeds. For most of the country, the cable operator’s top speed is 50/5Mbps.

Ralph Brown, chief technology officer of CableLabs, talked about DOCSIS 3.1 and the cable industry’s future technology needs in this interview from March 2013. (5 minutes)

AT&T U-verse customers hoping for speeds faster than 24Mbps may have significant hurdles to overcome to qualify for a speed boost up to 45Mbps.

AT&T realized they were at a disadvantage in the broadband speed race as their biggest competitors — cable operators — began transitioning to DOCSIS 3 technology and launched speed upgrades to 100Mbps or more for broadband customers seeking a faster online experience. In November 2012, AT&T announced Project VIP — an investment plan to expand and enhance AT&T’s U-verse service to approximately 57 million customer locations by the end of 2015. AT&T claims it has already upgraded 1.8 million U-verse broadband customer locations, including 500,000 U-verse video locations. As part of the upgrade, AT&T promises up to 100Mbps speeds in the future.

But customers are finding just getting 45Mbps more difficult than they first imagined. A report published by Broadband Reports explains why.

The new 45/6Mbps ‘Power Tier’ requires VDSL2 pair bonding, a technology used to increase the available bandwidth to a customer’s premise. Customers who can now purchase the Max Turbo (24Mbps) tier are the most likely to get manually qualified for 45Mbps service. It’s pot luck for almost everyone else.

Among those not qualifying are most customers in apartments, duplexes, townhouses, those served with ADSL2+ or xPON connections, or through network extenders like DSLAMs. AT&T’s website may offer availability information that suggests faster service might be available, until a technician arrives to explain it is not because the line length or copper quality between your home and AT&T disqualifies you.

With AT&T still dependent on its aging copper wire facilities, service variability will remain a fact of life and until fiber replaces more copper. AT&T customers should expect many of the company’s U-verse speed claims to be possible, not probable.

Some Clearwire customers remain unhappy when speeds are throttled to “manage” the network.

Clear (formerly known as Clearwire) has announced a general rate increase of about 10 percent for customers using its legacy 4G WiMAX broadband service.

As a result, most customers will pay about $5 more per month for fixed wireless or “on the go” broadband service.

“We instituted this to remain competitive and manage our costs,” a Sprint representative told Broadcasting & Cable. “Like our competitors, we must respond to customer trends, and provide a good user experience, and as a result we will make adjustments to fees and services from time to time. Our offer is still comparable to other offerings in the marketplace.”

Some customers would argue with Sprint’s definition of a “good user experience,” as complaints continue about heavy-handed throttling of Clear’s service that makes high bandwidth applications painful or impossible to use in the evening.

Stop the Cap! reader Akos contacted us this week to complain Clear still advertises and contracts for “unlimited data and top speeds,” while not exactly being upfront about targeting certain traffic for a prime time speed throttle that effectively keeps customers from streaming video.

“They openly admit their service is being throttled by software at each tower site that activates when it detects streaming video services like Netflix, reducing speed from 1.3Mbps to as little as 20kbps, rendering it unusable,” said Akos.

The speed throttle is usually active from 8pm-1:30am daily, when traffic is anticipated to be highest. Clear speaks about its network management speed throttle in the fine print: its Acceptable Use Policy.

Akos complains Clear’s speed throttle makes it easy to blame the streaming service, not Clear itself, because customers running speed tests will not see throttled speeds.

“It fools people to think the problem is on their end or with the streaming service, so customers don’t complain to Clear,” says Akos.

As a result, people using streaming video services get about 30 seconds of uninterrupted video before the throttle kicks in bringing extensive buffering delays.

Clearwire’s Speed Throttle Subject of Lawsuits

Clear’s own 2010 marketing promises unlimited usage with no speed reductions, like those “other” providers.

Clearwire’s speed throttle has been a part of life with the wireless service since 2010. Clearwire had significant legal exposure over its choice of network management because the company routinely advertised “unlimited service” with no speed throttles or overlimit fees. At least three lawsuits were filed against the company for its undisclosed throttling practices, eventually condensed into a single class action case that was finally settled last month.

Under the terms of the settlement, Clear admits no wrongdoing, but will clearly disclose it uses “network management” practices — a term that generally means usage caps and/or speed throttles — and will give customers information about the speeds they can expect when the throttle is active. As of today, Clear has not done that. Clear also volunteered to suspend term contracts and waive early termination fees for customers complaining about speed issues.

At least seven law firms handling the case will split a total award fee of $1,887,792.91 and expenses of $62,207.09. Individual representative plaintiffs each receive up to $2,000. Everyone else identified as part of the class action case that returned a claim form prior to Jan. 3, will receive an average of less than $30:

• a 50% refund of any early termination fee charged after a customer canceled service because of speed throttling;
• a rebate of $14 for customers signing up for Clearwire before Sept. 1, 2010 and experiencing speed throttling or a rebate of at least $7 for Clearwire customers signing up on or after Sept. 1, 2010;
• plus varying amounts for each month of service prior to Feb. 27, 2012 during which Clearwire’s records show it throttled a customer’s Internet speed. Customers throttled at 0.25Mbps will receive $5.00 for each month throttled, 0.60 Mbps: $3.00, and 1.0 Mbps: $2.00.

Court documents reveal of the 2,733,406 customers identified in Clearwire’s records as being speed throttled, only 83,840 submitted timely claims as part of the class action case. This represents a claims rate of about 3.1%. Of those, 76,199 were for speed throttling, 2,331 were requests for reimbursement of early termination fees.

The Future of Clear’s WiMAX and Sprint’s 4G

Sprint purchased the assets of Clearwire Corporation in July, rebranded the network “Clear,” and as of the end of August, stopped selling WiMAX devices to customers. Although Clear will still activate existing equipment, potential new customers are being marketed broadband plans on the Sprint network instead.

Former Clear dealers have received word Sprint plans to eventually decommission its acquired WiMAX network as early as 2014, most likely by gradually converting portions of the 2.5GHz spectrum Clear’s WiMAX service now uses in favor of Sprint’s 4G LTE service in urban and high congestion areas. Clearwire itself was in the process of adopting a variant of 4G LTE technology that would gradually replace the outdated WiMAX standard when Sprint acquired the company.

Although Sprint runs its own 3G network, it partnered with Clearwire to provide 4G WiMAX for Sprint customers. In 2011, Sprint announced it would stop selling devices with built-in support for WiMAX and announced it would launch its own 4G LTE network. Sprint will adopt the same version of LTE other North American carriers are using: FD-LTE, or Frequency Division LTE, which requires one transmit channel and one receive channel. But it will also support and continue Clearwire’s upgrade to TD-LTE, or Time Division LTE, a slightly different standard that supports receiving and transmitting signals on a single frequency at slightly different time intervals, providing enhanced spectrum efficiency. At least 5,500 towers should be active with TD-LTE service by the end of this year. End users will care only to the extent their devices support one or both standards.

Sprint’s 4G LTE rollout will depend primarily on higher frequency spectrum that is disadvantageous indoors and over extended distances. Sprint’s competitors AT&T and Verizon Wireless primarily depend on lower 700MHz frequencies that penetrate buildings better and can serve a larger coverage area. But a combination of Sprint and Clearwire’s spectrum assets give Sprint the most wireless spectrum of any U.S. carrier, which means potentially faster speeds and more capacity.

• 1900MHz: Sprint’s primary 4G FD-LTE service is now available in 151 cities on more than 20,000 cell towers;
• 2500MHz: Now used by Clear’s legacy WiMAX network, will see a transition towards Sprint’s TD-LTE service which will be targeted to urban and high congestion areas from “small cell” sites;
• 800MHz: The former home of now-shuttered Nextel, Sprint will eventually launch FD-LTE service on this band which will offer better indoor and marginal area reception.

Customers can expect devices that support both FD-LTE and TD-LTE in 2014.

CenturyLink is seeking “greater flexibility” to set its own prices, terms and conditions of service without a review by Washington State regulators, even as its broadband customers complain about bait and switch Internet speeds and poor service.

Three years after the Monroe, La., based independent phone company purchased Qwest — a former Baby Bell serving the Pacific Northwest — CenturyLink continues to lose customers to cell phone providers and cable phone and broadband service. Since 2001, CenturyLink and its predecessor have said goodbye to 60 percent of their customers, reducing the number of lines in service from around 2.7 million to just over 1 million.

CenturyLink is apparently ready to lose still more after upsetting customers with a notice it intended to seek deregulation that could lead to rising phone bills.

Docket UT-130477, filed with the Washington Utilities and Transportation Commission (WUTC) proposes to replace currently regulated service with what CenturyLink calls “an Alternate Form Of Regulation.” (AFOR)

If approved, CenturyLink will “normalize” telephone rates in Washington State, language some suspect is “code” for a rate increase. For CenturyLink customers in cities like Seattle, Spokane, and Tacoma, the maximum rate permitted for basic phone service for the next three years will be $15.50 (unless a customer already pays more), before calling features, taxes, and surcharges are applied. Most observers, including the state regulator, suspect CenturyLink will limit rate hikes to $1-2 if approved. A higher increase might provoke more customers to leave.

“We don’t think they can do much because, in our view, all (a big rate increase) is going to do is accelerate people dropping the landline into their homes,” Brian Thomas, a spokesman for the Washington Utilities and Transportation Commission told The Spokesman-Review. “A lot of people are cutting the cord.”

Frontier Communications, which previously won its own case for deregulation within its service areas including Everett, Wenatchee, and Tri-Cities, raised rates about $1 beginning this month.

A spokesman for the company confessed Frontier’s phone service is becoming obsolete.

“It’s safe to say plain old telephone service is in the process of becoming archaic for some people,” Frontier’s Carl Gipson said. “Five years from now, it will be almost – but not quite – extinct.”

Every rate change seems to provoke a review of whether landline service is still necessary.

Earlier this year, CenturyLink jumped on board legislation that purposely increased phone rates by several dollars a month by removing the sales tax exemption on residential telephone service. Wireless companies did not enjoy the same exemption and sued for parity.

A confidential settlement with state regulators made Washington phone customers, instead of telecom companies, liable for the sales tax starting in August. As a result, some residential phone bills went up at much as $5 based on retroactively charged sales tax.

Customers sticking with CenturyLink often say it is the only broadband provider in rural towns across the state. Although better than satellite broadband, the lack of regulatory oversight and technology investments have allowed CenturyLink to sell Internet speeds it cannot provide to customers.

At a hearing held this week by the San Juan County Council, members criticized CenturyLink officials on hand for selling fast service but delivering slow speeds to the group of islands between the mainland of Washington State and Vancouver Island, B.C.

Hughes

“Last night I did a speed test at my house and I am paying for 10Mbps but only getting 4.74Mbps,” complained Councilman Rick Hughes (District 4 – Orcas West). “I am paying for 10 and I am only getting 5Mbps, so how is that fair? There has been a ton of frustration over the last two years we have worked on this broadband issue. Everywhere I go and every meeting I talk to all I hear is complaints about CenturyLink. No matter what they are paying for, it’s a poor broadband connection to the end customer.”

CenturyLink provides broadband to 88% of the territory the company serves in Washington. Like most telephone companies, CenturyLink relies on DSL in much of its footprint and has upgraded central offices, remote equipment, and the telephone lines that connect them. On the San Juan Islands, most customers used to receive 1-3Mbps, but CenturyLink claimed at this week’s hearing it spent billion on infrastructure improvements that can now deliver faster Internet service across the state. In San Juan County, CenturyLink claims:

• 58% of all qualified addresses were upgraded to 10-25Mbps;
• 66% now qualify for more than 10Mbps (but less than 25Mbps) versus 46% prior to upgrades;
• 29% of customers now qualify to sign up for 25Mbps service.

CenturyLink warned the council its speed claims were not to be taken literally, noting DSL “speed is dependent on distance from equipment; speeds drop quickly as distance increases.”

Hughes told CenturyLink officials residents appreciated the investment, but customers were still disappointed after being promised higher speeds than actually received.

“When people call customer service, there is always an excuse about why there is a problem,” said Hughes. “If people are paying for something, they want to receive it.”

“For our long-term financial interests in this county, we need to have reliable 10-25Mbps service to customers on any part of the islands,” Hughes added. “My goal has always been 90+ percent should be able to get 25Mbps or better connectivity in the county.”

The problem for CenturyLink is the amount of upgrade investment versus the amount of return that investment will generate. San Juan County is disconnected from the mainland and collectively house only 15,769 residents. But it is also the smallest of Washington’s 39 counties in land area, which can make infrastructure projects less costly.

CenturyLink committed to continue investment in its network “where economically feasible.”

San Juan County’s Orcas Power & Light Cooperative (OPALCO), a member-owned, non-profit cooperative electric utility may have a partial solution to the problem of meeting Return on Investment requirements.

OPALCO originally proposed a hybrid fiber-wireless system designed to reach 90% of the county with a $34 million investment, to be built over two years. When completed, all county residents would pay a $15 monthly co-op infrastructure fee and a $75 monthly fee for broadband and telephone service. To gauge interest, OPALCO asked residents for a $90 pre-commitment deposit. By the annual meeting in May, the co-op admitted only 900 residents signed up and it needed 5,800 customers to make the project a success.

Some residents balked at the high cost, others did not want wireless broadband technology, and some local environmental activists wanted OPALCO to focus on clean, affordable energy and avoid the competitive broadband business.

The lack of commitment forced the co-op to modify its broadband plans, offering a “New Direction” to residents in June 2013.

OPALCO elected to stay out of the ISP business and instead announced a public-private initiative, providing fiber infrastructure to existing service providers. In effect, the co-op will cover the cost of building fiber extensions where CenturyLink is not willing to invest. For a $3-5 million investment from the co-op, ISPs like CenturyLink will be able to commission OPALCO to build fiber in the right places to make DSL service better. CenturyLink would have non-exclusive rights to the fiber network and would have to pay the co-op a service lease fee.

Unlike ISPs in other communities that have shunned publicly funded fiber infrastructure, CenturyLink says it will contemplate a trial — buying bandwidth from OPALCO instead of enhancing its own fiber middle mile network — to test what level of improved service CenturyLink can offer customers.

Regardless of CenturyLink’s plans, OPALCO is moving forward installing limited fiber connections as part of an effort to develop a more modern electric grid.

“Our data communications network brings exponential benefit to our membership,” OPALCO notes. “It includes tools that allow the co-op to: control peak usage and keep power costs down, remotely manage and control the electrical distribution system, manage and resolve power outages more efficiently, integrate and manage community solar projects and improve public safety throughout the county.”

There are some drawbacks, reports Wally Gudgell from The Gudgell Group.

“It will take longer to implement, and will impact fewer businesses and households,” Gudgell writes. “While about two-thirds of the islands will eventually be covered, more remote areas will have to work with a local ISP and potentially pay more for service.  DSL coverage for homes that are further than 15,000 feet from CenturyLink fiber-served distribution hubs will be challenging. Some homeowners may need to pay for fiber to be run to their homes by Islands Network (fiber direct is costly, estimated at $20/foot).”

Time Warner Cable has added two new lobbying firms, despite running up nearly $4 million in lobbying expenses during the first half of 2013, to advocate a hands-off policy on broadband and changes in how television stations get compensated from cable providers after a month-long dispute with CBS helped fuel subscriber losses.

The Legal Times blog reports Time Warner Cable has hired Dentons and Edwards Wildman Palmer to advocate the company’s positions on broadband deployment, copyright reform, privacy matters, retransmission consent, and the reauthorization of the Satellite TV Extension and Localism Act. Provisions of that legislation have given television stations and broadcast networks leverage to persuade pay television providers to meet their terms on higher compensation in return for permission to carry those signals on the cable or satellite lineup.

Nelson

In reviewing disclosures released by the clerk of the House of Representatives obtained by Stop the Cap!, Time Warner Cable will benefit from Washington’s revolving door, using lobbyists that either used to work inside offices of members of Congress or have been directly involved in writing or influencing legislation for paying clients:

Valerie Nelson, a senior managing director at Dentons, served as director of Member Services for Majority Leader Eric Cantor (R-Va.) in the U.S. House of Representatives.

Todd Bertoson, also a senior managing director at Dentons, spent nearly six years on the U.S. Senate Committee on Commerce, Science, and Transportation, working on all aspects of the committee’s agenda, including issues involving the Federal Communications Commission (FCC).

Bertoson

Seth A. Davidson, a lobbyist from Edwards Wildman Palmer, has played an active role, including drafting legislation and witness testimony, in most legislative matters affecting the communications industry over the past three decades, including the 1984 and 1992 Cable Acts, the Digital Performance Right in Sound Recordings Act of 1995, the 1996 Telecommunications Act, the Digital Millennium Copyright Act, and the Satellite Home Viewer Act of 1989 and each of its subsequent renewals. His involvement in legislative matters of interest to his clients is so pervasive, he was singled out by the chairman of the Senate Judiciary Committee in 2004 for his contributions (on behalf of his clients) in the drafting of the Satellite Home Viewer Extension and Reauthorization Act.

The Legal Times notes Time Warner Cable has spent $3.8 million on federal lobbying during the first half of this year, according to congressional records. For its advocacy efforts, the company used its own staffers, as well as lobbyists from firms that included Capitol Tax Partners; Fierce, Isakowitz & Blalock; and The Raben Group.
