CableLabs has resolved the cable industry’s long-standing competitive disadvantage with fiber optic broadband with the introduction of a Full Duplex (FDX) DOCSIS 3.1 specification.

“FDX DOCSIS 3.1 is an extension of the DOCSIS 3.1 specification that will significantly increase upstream capacity and enable symmetric multi-Gbps services over existing HFC networks,” CableLabs wrote. “Full Duplex DOCSIS 3.1 technology builds on the successful completion of the DOCSIS 3.1 specification, which has made deployments of 10Gbps downstream and 1Gbps upstream broadband speeds a reality.”

Cable operators that adopt FDX will be able to sell identical upstream and downstream speeds to customers. The new standard concurrently uses the same spectrum reserved for broadband service for uploads and downloads. The technology was developed using Time Division Duplexing (TDD).

The new standard is 100% compatible with DOCSIS 3.1, which is slowly being implemented by cable operators around the country. However, it is not compatible with DOCSIS 3.0, which is still the predominate cable broadband technology standard in use in North America. As DOCSIS 3.1 gradually gets introduced, some cable modem manufacturers are building modems compatible with both DOCSIS 3.0 and 3.1, so equipment is not rendered obsolete in the next few years. But early adopters will likely not find modems supporting FDX DOCSIS 3.1 for up to two years.

The prerequisites for cable operators interested in deploying the new standard are significant. The most important requirement is the adoption of “node+0” architecture, which requires deploying fiber optics deep into the cable company’s network.

The history of the DOCSIS standard powering cable broadband.

How cable systems work

In the early days of cable, companies relied primarily on coaxial cable between its “headend” — often its main office, and customers. In the late 1980s and early 1990s, cable companies began replacing sections of its copper coaxial cable with fiber optics, a more reliable technology with fewer failure points. There was considerable debate about how much copper cable should be scrapped, based primarily on the cost to deploy fiber. More fiber = more money, less fiber = less reliability. Anyone who subscribed to cable in the 1970s and 1980s was well acquainted with frequent outages, often caused by a failure in one of the many amplifiers cable system operators used to get signals from their office to individual customers.

Many cable companies eventually settled on plotting each fiber optic route to the center of a circle on a map with a 1-kilometer radius. In most suburban areas, this meant that each fiber “node” would serve around 500 customers. The cable company would continue to use its existing coaxial cable to extend into neighborhoods and reach subscribers. Over the last 5-10 years, some cable companies have invested to push fiber optics “deeper” into their networks, which means further reducing the amount of copper coaxial cable still in use.

Today, in many cities, the average cable subscriber can theoretically find the location where a cable company’s fiber connection interfaces with coaxial cable somewhere within a three block radius.

To make FDX DOCSIS 3.1 work, cable companies need enough fiber pushed towards customers to completely eliminate the use of amplifiers. That is what “node+0” means: from the fiber node to the customer, there are zero amplifiers.

Timeline

Because of the cost implications, some cable operators may initially offer FDX DOCSIS 3.1 only to their commercial clients, especially in areas where a fiber competitor does not exist.

Although many cable operators doubt symmetrical broadband is attractive to residential customers, it does offer the cable industry the talking point its networks will be gigabit-capable without an investment in fiber to the home service.

The cable industry expects to test the technology in late 2018 or early 2019, with the expectation it will be introduced for sale starting in 2020.

Pai

“We want to eliminate, as much as we can, government regulation of the telecommunications marketplace so as to permit present players to provide new and innovative services to consumers and likewise permit new players to come in and compete,” FCC Chairman Ajit Pai told an audience attending a speech at the Ronald Reagan Library in Simi Valley, Calif.

He was quoting and affirming words first spoken by Reagan era FCC Chairman Mark Fowler. It was a core theme in Pai’s speech, entitled “Morning in Digital America,” and it signaled Pai and his Republican colleagues would do everything possible to inspire and affirm the country’s largest telecom companies’ investments that he felt would only grow with the obliteration of rules and regulations established by his predecessor during the Obama Administration.

Pai cited the wireless industry’s transition to 5G service, quoting the CTIA — the wireless industry’s top lobbying organization, as creating “three million jobs and over $500 billion in additional economic growth over seven years.”

“The most powerful tool for expanding digital opportunity is market-based, light-touch regulation—for this maximizes private investment in high-speed networks,” Pai predicted. “That’s why we’ve sought to break down regulatory barriers to installing wireless and wireline infrastructure. Too often, government at all levels makes it hard for companies to construct next-generation networks. So we’re focused on cutting as much of this red tape as we can.”

Pai also claimed he restored the “collaborative and collegial traditions of the FCC.”

“Under my leadership, about 80% of the major items voted on at our monthly meetings have been approved with bipartisan support and without dissent, compared to less than 50% under my predecessor,” Pai claimed.

All but one of the current commissioners were in place during the second term of the Obama Administration, meaning under Pai’s predecessor, it was Republican commissioners Pai and O’Rielly that dissented the most at the time.

As the wireless industry awaits an announcement that T-Mobile and Sprint have an agreement to merge, some on Wall Street are skeptical the merger deal will win approval, especially if Republicans lose their majority in the House and Senate in the 2018 mid-term elections.

Matthew Niknam of Deutsche Bank has warned his clients any merger deal not approved by next November is more likely to fall apart if  Democrats take back control of Congress:

“There also may be greater incentive for both sides to evaluate a potential deal sooner rather than later, given the risk that deal approval may slip beyond mid-term elections in late 2018 (with the risk that more populist/less corporate-friendly sentiment may become more pervasive in D.C.) In fact, we note that the Democrats’ ‘Better Deal’ agenda (unveiled in July 2017, targeted towards 2018 elections) highlights ongoing corporate consolidation as a threat to U.S. consumers, and proposes sharper scrutiny of potential deals.”

Nikram writes there has not been a lot of interest by cable operators to acquire Softbank’s Sprint, which has been effectively up for sale or merger for at least a year.

Fierce Wireless notes Cowen & Company Equity Research last month suggested the chance of a merger between T-Mobile and Sprint was now 60-70%, down from 80-90% originally. The reason for the pessimism is their estimate that any deal’s chance of winning approval was only about 50%. The odds get even worse if the Democrats start to check the Trump Administration’s power.

Public policy groups and well-compensated industry opinion leaders are already preparing to wage a PR war over a deal that would reduce America’s major wireless carriers to just three.

Professor Daniel Lyons, well-known for writing pro-industry research reports defending almost anything on their corporate policy wish list, is hinting at a possible strategy by the merging carriers by suggesting neither could survive without a merger.

Good analysis but incomplete. This assumes #Sprint and #TMobile would both remain viable w/o merger. I’m not convinced (either way yet). https://t.co/8WaZ2b8iJT

Most analysts predict that with just three national wireless carriers, the U.S. wireless marketplace would more closely resemble Canada — widely seen as more carrier-friendly and expensive.

Wall Street analysts are debating exactly how many tens of thousands of jobs will be lost in a merger, and the numbers are staggering.

Jonathan Chaplin of New Street Research predicts the merger would cost the country more jobs than now exist at Sprint.

He predicts “approximately 30,000 American jobs” will be permanently lost in a merger. Together the two companies currently employ 78,000 — 28,000 at Sprint and 50,000 at T-Mobile.

Craig Moffett of MoffettNathanson Research was more conservative, predicting 20,000 job losses would come from a merger. But the impact would not be limited to just direct hire employees.

“We conservatively estimate that a total of 3,000 of Sprint and T-Mobile’s branded stores (or branded-equivalent stores) would eventually close,” Moffett’s report said.

Golden parachutes will make some executives at Sprint and T-Mobile very wealthy if a merger succeeds.

Many T-Mobile and Sprint stores are located in malls and retail “power centers” where maintaining both stores would be unnecessary. Also hard hit would be wireless tower owners and those employed to care for them. Most believe Sprint’s CDMA wireless network would eventually be decommissioned in a merger, and many of its cell sites would be mothballed. Sprint’s biggest asset is its currently unused trove of high frequency wireless spectrum it could use to deploy future 5G services, but those services would likely be provided from small cells mounted on utility poles and street lights.

The biggest winners in any deal will likely be top executives at Softbank, Sprint, and T-Mobile, Wall Street banks providing deal advisory services and financing, and shareholders, who can expect higher earnings from a less competitive marketplace. Fierce competition from T-Mobile and Sprint were both directly implicated for threatening revenues for all four wireless companies, who have had to respond to aggressive promotions by cutting prices and offering more services for less money.

The Trump Administration’s choices of Ajit Pai for Chairman of the FCC and Makan Delrahim as United States Assistant Attorney General for the Antitrust Division of the Justice Department are both widely seen as signals the White House is not going to crack down on competition-threatening merger deals. Mr. Pai has recently improved the foundation for a T-Mobile/Sprint merger by declaring the wireless industry to be suitably competitive, something required before seriously contemplating reducing the number of competitors.

Eight Democrats sent a letter to the FCC chairman last week calling on both the FCC and the Justice Department to begin an investigation into the possible merger as soon as possible, citing possible antitrust concerns.

The text of the letter:

Dear Chairman Pai and Assistant Attorney General Delrahim:

We write to ask you to begin investigating the impact of a merger between T-Mobile International and Sprint Corporation. According to Pew Research, over three-quarters of Americans now own smartphones, driven by a 12 percent increase in smartphone ownership among adults over age 65 and a 12 percent increase in smartphone ownership in households earning less than $30,000 a year since 2015. Today, smartphones are not really just phones at all. For many, they are the primary connection to the internet. An anticompetitive acquisition would increase prices, burdening American consumers, many of whom are struggling to make ends meet, or forcing them to forego their internet connection altogether. Neither outcome is acceptable.

We believe that an investigation is appropriate for three reasons. First, aggressive antitrust enforcement benefits consumers and competition in the wireless market. Second, a combination of T-Mobile and Sprint would raise significant antitrust issues and could dramatically harm consumers. Third, although a deal has not been announced, the two parties have made repeated attempts to merge, and current reports suggest they are close to an agreement. Your agencies should be in a position to fully – but expeditiously – investigate and analyze this deal should it occur.

Competition among wireless carriers has lowered prices, increased quality, and driven innovation

Consumers have benefited from competition among the four national carriers, and we have effective antitrust enforcement to thank for that competition. In the summer of 2011, the Department of Justice’s (DOJ) Antitrust Division filed suit to block AT&T’s proposed acquisition of T-Mobile despite claims that T-Mobile was a weak competitor and, without the deal, remaining options “won’t be pretty.”  The FCC likewise outlined its opposition to the deal that fall. The deal collapsed, but T-Mobile did not. It competed. It spent billions improving its network, and it offered better terms; for example, it eliminated two-year contracts and data overages. It enticed customers to switch providers by paying their termination fees. And, its competitors had to respond in kind. As William Baer, former head of DOJ’s Antitrust Division, has explained, consumers have enjoyed “much more favorable competitive conditions” since that transaction was blocked.  In May 2017, the Wall Street Journal reported that cellphone plan prices were down 12.9 percent since April 2016, the largest decline in 16 years, and attributed the drop to “intense competition” among the top cell service providers: Verizon, Sprint, T-Mobile, and AT&T.  Paul Ashworth, chief U.S. economist at Capital Economics, specifically suggested that it was caused by the “price war that has broken out among cell-phone service providers, with all the big providers now offering unlimited data plans at cheaper rates.”

Further, the fact that T-Mobile and Sprint appear to be each other’s primary competitor raises additional concerns about this potential horizontal merger. That direct competition has particularly benefited lower-income families and communities of color, many of whom rely on mobile broadband as their primary or only internet connection.  Sprint and T-Mobile have offered products and service options that are more appealing to lower-income consumers. For example, T-Mobile was the first major carrier to offer a no contract plan,  and both Sprint and T-Mobile have been leaders in offering prepaid and no credit check plans, which allow people who may have poor credit to obtain a cell plan and ultimately access the internet.

A combination of T-Mobile and Sprint would raise significant antitrust concerns

Not surprisingly, when T-Mobile and Sprint first discussed a merger in 2014, both of your predecessors expressed skepticism. William Baer stated that “[I]t’s going to be hard for someone to make a persuasive case that reducing four firms to three is actually going to improve competition for the benefit of American consumers.”  Similarly, former FCC Chairman Tom Wheeler simply explained, “[f]our national wireless providers are good for American consumers.”

What is surprising, however, is that a few years later the two companies have revived their merger talks. Whether one looks at cellphone competition as a national market or as numerous local markets, T-Mobile’s acquisition of Sprint would very likely be presumptively anticompetitive. We are concerned that this consolidation would increase prices, reduce incentives to offer new plans, and allow the remaining carriers to curtail their investment in their networks. Further, given both companies’ focus on competing for lower-income customers, the combination of Sprint and T-Mobile could disproportionately harm those consumers. In addition to potentially raising retail prices, the remaining carriers are also likely to increase prices to companies like Straight Talk, which buys bulk access to one or more of the four national carriers and advertises almost exclusively to lower-income communities.

T-Mobile and Sprint will no doubt claim that the merger will leave sufficient competition, increase cost savings, and spur investment. The agencies will need to examine these issues in depth and make the ultimate determination as to whether the effect of such a deal would be to undermine or promote competition. The very complexity of the issues only further justifies the need for the agencies to begin examining the markets and investigating the competitive dynamics sooner rather than later.

Initiating an investigation is appropriate

Although the antitrust agencies often wait for an official filing before opening an investigation, nothing requires this delay. For example, in May, the Antitrust Division announced an investigation of the possible acquisition of the Chicago Sun-Times by the owner of the Chicago Tribune.  The two companies in question here have had a longstanding interest in combining, and, according to reports, an agreement between Sprint and T-Mobile may be weeks away.

Beginning an investigation into a merger of T-Mobile and Sprint now will allow your agencies to quickly, but fully, review the agreement if it is announced. Indeed, multiple news sources are reporting that the two parties are close to a deal in principle. The likelihood of the transaction occurring combined with the serious issues that it raises provide compelling reason for DOJ and the Federal Communication Commission to begin investigating the potential transaction.

For the reasons stated above, we urge you to begin to examine this potential transaction now. Competition among four major cell phone carriers has benefited consumers with lower prices, better service, and more innovation. We are concerned that consolidation will thwart those goals. Thank you for your prompt attention to this matter.

Sincerely,

WWOR advertises itself as My 9, but the station actually transmits over UHF channel 38 and will move to channel 25 early next year.

T-Mobile today announced a partnership with FOX Television Stations to hasten channel relocation to make room for the wireless carrier’s expansion of wireless service in the 600MHz spectrum it won at auction.

As part of the agreement, FOX-owned WWOR-TV in Secaucus, N.J., will vacate its current digital UHF channel 38 in early 2018, over a year sooner than originally planned. The station will move to UHF channel 25, but most viewers will still find the channel on virtual channel 9. T-Mobile will then bring new cell service online in metropolitan New York where WWOR’s signal used to be.

T-Mobile is aggressively trying to bring its valued 600MHz spectrum online as quickly as possible because it offers the carrier and its customers expanded coverage and better reception in indoor locations. Although the FCC has set an August 2019 deadline for stations to vacate and move their channels to make way for improved cell service, T-Mobile is offering incentives to get broadcasters to make the move well before that deadline.

Earlier this year, PBS and America’s Public Television Stations announced a similar partnership with T-Mobile. The wireless carrier has offered to pay the costs for a significant number of rural TV translators to move to new channel positions to make room for T-Mobile’s cell expansion.

“We’re committed to working with broadcasters across the country to clear 600MHz spectrum, so we can preserve programming and bring increased wireless choice and competition across the country,” said Neville Ray, chief technology officer at T-Mobile.

Working with the low power television outlets is a win-win solution for T-Mobile and the stations, because some budget-constrained stations may be required to change channel positions at least twice. There are concerns that the diminishing UHF TV dial may not have room to accommodate every TV station that wants to remain on the air.

With many cable operators reporting a need to double network capacity every 18-24 months to keep up with customer traffic demands, the industry is spending time and money contemplating how to meet future needs while also finding ways to cut costs and make networks more efficient.

Top technology executives from five major cable operators answered questions (sub. req’d.) from Multichannel News about their current broadband networks and their plans for the future. Some, like Mediacom, are aggressively adopting DOCSIS 3.1 cable broadband upgrades for their customers while companies like Cox and Comcast are deploying multiple solutions that use both traditional hybrid fiber-coax network technology and, on occasion, fiber-to-the-home to boost speed and performance. But at least one cable company — Charter Communications — thinks it can continue operating its existing DOCSIS 3 network without major upgrades for several years to come.

Cable Broadband Traffic Can Be Handled

“We’ve been on a pretty steady path of doubling our network capacity every 18-24 months for several years, and I don’t see anything that makes me think that will change,” said Tony Werner, president of technology and product at Comcast. “We’ve been strategically extending fiber further into our network to meet customer demand, and that effort, combined with our commitment to deploying DOCSIS 3.1 has given us a network that’s powerful, flexible, and ready for what’s next.”

J.R. Walden, senior vice president of technology at Mediacom was more aggressive.

“We have completed the removal of all the analog channels. That was the big step one,” Walden said. “Step two was to start transitioning high-speed data over to DOCSIS 3.1, so we’re not adding any more 3.0 channels, and reuse spectrum for 3.1, which is a bit more efficient. The whole company is 3.1, all the modems we’re buying since June have been 3.1, so we’ve begun that next transition.”

Walden added Mediacom is also trying to improve broadband performance by reducing the number of customers sharing the same connection.

“We average about 285 homes to 290 homes per node as an average,” he said.

Mediacom is also scrapping older technology on the TV side to open new bandwidth. The cable company is getting rid of MPEG-2-only set-top boxes so the company can transition its video lineup to MPEG-4. But even that won’t last long. Walden admits the company will then quickly start moving less-viewed channels and some premium networks to IP delivery.

Traditional cable broadband service relies on a hybrid fiber-coax network.

In its European markets, Liberty Global has adopted Converged Cable Access Platform (CCAP) equipment across its footprint. CCAP technology saves cable operators space and operates more efficiently, and supports future convergence of technologies that cable operators want to adopt in the future. CCAP has helped Liberty Global deal with its 45% traffic growth by making upgrades easier. The company is also using advanced features of CCAP to better balance how many customers are sharing a connection. The next step is adopting DOCSIS 3.1.

“Seventy to 80% of our plant will be DOCSIS 3.1 ready by the end of next year, giving us a path to even greater capacity expansion allowing us to continue to increase the available capacity across our access network, upstream and downstream,” said Dan Hennessy, chief architect of network architecture for Liberty.

Charter is prioritizing maximizing performance on the network it already has.

“Our priority is to constantly balance capacity against demand. It’s a never-ending quest,” said Jay Rolls, Charter’s chief technology officer. “We watch it very closely, and we’re very pragmatic about it — the volume of tools, metrics and ways to see what’s really happening, and invest accordingly, is really deepening in ways that matter.”

Is Fiber-to-the-Home in Your Future?

While some cable operators like Altice’s Cablevision are scrapping their existing hybrid fiber-coax networks in favor of fiber-to-the-home (FTTH), America’s largest cable operators are not in any hurry to follow Altice.

Comcast has expanded its fiber network closer to customers in the last few years, but sees no need to convert customers to FTTH service.

“I feel pretty strongly that the best path ahead is to leverage the existing coaxial network and DOCSIS resources to the fullest, then inch towards FTTH, over time Why? Because we can. We don’t have to build an entire network just to turn up one customer.”

The next generation of cable broadband service may depend on CCAP – technology that will cut operator costs and lay the foundation for changing the way video and other services are delivered to customers.

Cox has a 10-year Network 2.0 plan that will bring fiber closer to customers, but not directly to every home. More important to Cox is having the option to support symmetrical speeds, which means delivering upload speeds as fast as download speeds. In the meantime, network cabling Greensboro can improve your current connectivity and reliability, preparing your network for high-speed internet.

“We’re also thinking about the fiber investment and fiber deep as it relates to our wireless strategy, enabling some of our customers with a small cell strategy but also positioning ourselves to take advantage of that in the future, as well as thinking about fiber deep to benefit both residential and our commercial customers simultaneously,” said Kevin Hart, Cox’s executive vice president and chief product and technology officer.

Liberty/Virgin Media’s Project Lightning is bringing cable broadband and TV service to places in the UK that never had cable service before.

In Europe, Liberty Global’s “Project Lightning” network expansion initiative is building out traditional cable service in the United Kingdom. Most of the UK never adopted cable service, favoring small satellite dish service instead. Now Liberty Global is putting cable expansion on its priority list. But decades after most North Americans got cable service for the first time, today’s new buildouts are based largely on fiber optics — either fiber to the home or fiber to the neighborhood, where coaxial cable completes the journey to a customer’s home.

Charter admits the technology it will use in the future partly depends on what the competition is offering. Rolls says the company can eventually roll out DOCSIS 3.1, take fiber deeper, or offer symmetrical download/upload speeds presumably targeted towards its commercial customers. But he also suggested Charter’s existing network can continue to deliver acceptable levels of service without spending a lot on major upgrades.

“It’s a rational approach, where we’re trying to balance the needs, the available technologies, and the costs,” Rolls said. But he also suggested DOCSIS 3.1 isn’t always the answer to upgrades. “DOCSIS 3.1 has some pretty remarkable capabilities, but it’s not necessarily a hard-and-fast reason to not take fiber deeper, for instance [allowing for additional DOCSIS 3 node splits]. Different situations drive different capacity decisions.”

Walden agreed, and Mediacom customers should not expect more than DOCSIS 3.1 upgrades for the near future.

“[Fiber deep] is a bit further out, at least as a large-scale type of project,” Walden told Multichannel News. “I think fiber deep for multi-dwelling units, high-density areas and some planned higher end communities doing deeper fiber or fiber-to-the-home [is happening]. But as a wholesale [change] and going to node+0 kind of architecture, I don’t see that in the next two years.”

Are Symmetrical Speeds Important for Customers?

Verizon’s fiber to the home service FiOS uses symmetrical broadband speeds to its advantage in the marketplace.

Many fiber to the home networks offer customers identical upload and download speeds, but cable broadband was designed to favor downstream speeds over upstream. That decision was based on the premise the majority of users will receive much more traffic than they send. But as the internet evolves, some are wondering if cable broadband’s asymmetric design is now outdated and some competitors like Verizon’s FiOS fiber to the home service now use its symmetrical speed advantage as a selling point.

Cox Communications does not think most customers care, even though its network upgrades are laying the foundation to deliver symmetrical speeds.

“It’s a little but further out on the horizon,” said Hart. “The upstream growth rate is ticking up a couple of notches, but not to the tune that we would need significant additional capacity and/or a complementary need for symmetrical bandwidth. [A]t this stage, the symmetrical is a nice-to-have for residential and definitely will be a good option for our commercial customers.”

Rolls isn’t sure if symmetrical speeds are important to customers either and Charter has no specific plans to move towards upload speed upgrades.

“The world of applications and services continues to evolve, obviously, but so far we’ve been able to meet those needs with an asymmetrical topology,” Rolls said. “That said, things like real-time gaming, augmented and virtual reality, and the Internet of Things — some of those will likely drive more symmetry in the network. It remains to be seen.”
