No Demand for Gigabit?

Among the most-dangerous of statements is that something cannot be done, violates the laws of physics, costs too much, is too difficult to manage, or is not wanted by consumers or other users.

The reason such statements can be quite dangerous is that they are sometimes spectacularly wrong, in ways that dramatically affect whole indus

I can remember being at a meeting at the headquarters of the National Cable Television Association, in the earlier days of high definition television discussions, where it was proposed that a full HDTV signal could be squeezed from about 45 Mbps of raw bandwidth to the 6-MHz channelization used by the North American television industry.

The room essentially exploded, as the attendees, mostly vice presidents of engineering from the largest cable TV and broadcast firms, disagreed with the sheer physics of the proposal. Later, the executive who suggested HDTV in 6 MHz was indeed possible talked with his firm’s engineering vice president, about the the science, to reaffirm that such a thing actually could be done. “Are you sure about this?” was the question, given the magnitude of opposition.

To make a longer story short, it did prove feasible to compress a full HDTV signal into just 6 MHz of bandwidth, making for a much-easier financial transition to full HDTV broadcasting, as well as an ability for cable TV operators to support the new format.

Similarly, when the U.S. cable TV industry began to ask for analog optical transmission systems capable of carrying 20 channels of standard definition video without complicated channel-by-channel coding and decoding, a distinguished engineer from Bell Laboratories privately assured me that such a thing was in fact not possible, and that people who claimed it was possible were simply wrong.

To make a longer story short, it did indeed prove possible to take a full complement of analog video signals (40 channels, as it turned out), convert the full set of broadband signals to analog optical format, and deliver them over distances useful for cable TV purposes.

On another occasion, the vice president of one of the world’s biggest suppliers of equipment said privately that “digital subscriber line does not work” as a platform for high speed Internet access, even at relatively low speeds. Ultimately, that also proved incorrect. Over time, DSL performance was not only proven to be commercially viable, but also delivered much-faster speeds, over longer distances, as experience was gained.

The point is that when a smart, experienced, thoroughly-knowledgeable executive says that something “cannot be done,” one has to translate. What the statement means is only that, at a given point in time, before the application of effort and ingenuity, a given entity has not been able to do something.

That does not actually mean something literally “cannot be done.” Quite often, formerly impossible things actually are made possible, after dedicated investigation and development.

That applies to consumer demand for internet access, as well. It might well have been true two decades ago, or a decade ago, that there was no appreciable consumer demand for gigabit internet access, if such services could have been provided, and at retail prices those services would have cost, back then.

There was a time when the computing power (in constant dollar terms) of an Apple iPad 2, when Microsoft was founded in 1975, would have cost between US$100 million and $10 billion.

But when gigabit internet access is priced at a relatively modest premium to the standard offers (gigabit for $100, standard 200 Mbps for possibly $50 to $70), then there is much more demand.

“There is no demand for gigabit internet access” is a conditional statement. At some point, there will be lots of demand, on both mobile and fixed networks. All that has to happen is that price changes.

Comcast, for example, has increased the highest offered internet access speed at nearly Moore's Law rates. So the unstated qualifiers “at this price, at this time,” have to be kept in mind.

There will be a time, and a price, that has many, if not most, consumers buying gigabit rate internet access.

Technology Predictions are Often Spectacularly Wrong

Nobel prize winner (in chemistry) and physicist Ernest Rutherford (known for his work on nuclear physics) once experimented with radio waves, but gave it up when told radio had no future.

The point is that even the best and brightest minds in technology often are very wrong about how a particular innovation will develop. So humility is not a bad attitude for any market researcher to adopt.

In 1943, Thomas Watson, IBM CEO said “I think there is a world market for maybe five computers.”

Ken Olson, Digital Equipment Corp. president, in 1977 said “there is no reason for any individual to have a computer in his home.”

Western Union execs once argued the telephone “is inherently of no value to us.”

Thomas Edison said “fooling around with alternating current is just a waste of time.”

Others argued the automobile was a novelty or fad. Studio executive Daryl Zanuck once said “television won’t be able to hold on to any market it captures after the first six months.”

Even Marty Cooper, a mobile phone pioneer, once argued that “cellular phones will absolutely not replace local wire systems.”

Robert Metcalfe, a father of Ethernet, said “the internet will soon go spectacularly supernova and in 1996 catastrophically collapse.

Steve Ballmer, Microsoft CEO, once said “there’s no chance that the iPhone is going to get any significant market share.”

The point is that the best and brightest among us, and certainly even competent market researchers, can be spectacularly wrong. That might be especially the case when subjects we do not routinely cover start to reshape industries, markets and possibilities, but such dangers always exist, even in markets we do claim to cover.

“You don’t know what you don’t know” is one explanation for forecasting error. No forecaster is able to incorporate somewhat unplanned events such as major recessions, huge changes in underlying core technologies, wars, revolutions and other exogenous events that directly affect markets of any sort.

Also, we tend to work with two-dimensional spreadsheets. Reality necessarily is more complex than that. So humility always is a good attitude to maintain when making predictions.

Why Software-Defined Networks are Destined to be More Important

There is a good reason why software-defined networks are getting more attention. Simply, all business and consumer networking use cases are becoming “cloud-based” interactions that are themselves largely virtualized.  

For enterprises and businesses, that tends to mean a shift towards virtual private networks supporting mobile, remote and distributed users who require access to cloud-based computing resources, no matter where they are working. That also implies a need for security and quality of service support provided by VPNs.


So a reasonable person might conclude that the shift in enterprise networking will be in the direction of software-defined networking (SD-WANs, VPNs, virtualized core networks, network slicing).

Call Center Experience the Weakest Part of Service Provider Performance

Unhappiness with call center interactions seems to be the key reason for low customer satisfaction scores with linear video subscription services (no direct question about price or value-price relationship is asked).

And though fixed-line voice service ranks higher, the same pattern of unhappiness with call center experience occurs there. Call center experience also is the lowest-ranked feature of mobile satisfaction tracked by ACSI.

I cannot remember a time in three decades when cable TV services got high satisfaction ratings. Nor, since the American Customer Satisfaction Index (ACSI) began tracking internet service providers, do I recall ever seeing high satisfaction ratings for internet access service, either.

In fact,  “subscription television and internet service providers rank last among all industries tracked by the ACSI,” a placement that has been consistent for several years.

It appears much of the problem lies with customer interaction and customer support, especially the use of call centers.

Mobile phone services, on the other hand, score much higher, though not as high as the devices themselves. Fixed network phone service, perhaps paradoxically, not scores higher satisfaction than subscription TV or ISP service. The likely explanation there is that all the unhappy customers have left.

The 2018 annual ACSI report on such services only confirms the trend.


Customer satisfaction with subscription television service fell 3.1 percent to an ACSI score of 62, an 11-year low, ACSI says.

New indices for video on demand and video streaming initially show higher scores, with video streaming services on par with mobile phones.

Moore's Law Really Does Matter

Moore’s Law and optical fiber matter, where it comes to fixed network internet access speeds.

Back in the early 1980s, when I first got into the cable TV business, many rural systems were operating at less than 200 MHz of total analog bandwidth, the first big city franchises were about to be awarded, and the state of the art was systems promised to operate at 400 to 450 MHz.

All that was before optical fiber and the hybrid fiber coax architecture, the need for reliable two-way communications or data services.

Because of Moore’s Law advances and optical fiber, HFC physical bandwidth now pushes between 750 MHz and a gigaHertz and internet services now push between hundreds of megabits per second and a gigabit per second, using DOCSIS 3.1.


It is possible, perhaps likely, that bandwidth will grow further beyond planned improvements to DOCSIS 3.1.
Indeed there is early speculation about what might be possible with next-generation DOCSIS that harnesses new spectrum ranges. Other proposed ways of increasing symmetrical bandwidth require all-fiber networks and full-duplex networking, where the same bandwidth is used for both upstream and downstream communications.

The point is that advances in computing power, with lower prices, plus optical fiber, make possible amounts of commercial bandwidth that would have been unthinkable back in the early 1980s.

Nobody Knows "How Many" Facilities-Based Telcos Can Exist in a Mature Market

In most fixed network telecom markets, the reality is that only a single facilities supplier is financially sustainable on a national basis, so competition usually takes the form of wholesale obligations. Mobile markets historically have featured at least two to four facilities-based competitors.


But as in the fixed network market, there are questions about sustainable numbers of contestants as the market matures. Over time, fewer competitors are generally expected.


The big issue for regulators is how few competitors are required to provide the benefits of competition, but on a sustainable basis. And that answer is not yet known.


“The idea that the U.S. mobile market has an equilibrium of four firms (nationally, at least) is an emotional and not a scientific conclusion,” said George Ford, Phoenix Center for Advanced Legal and Economic Policy Studies chief economist.


In other words, four national providers might not be sustainable. That view is supported, Ford argues is entirely consistent with the financial struggles of Sprint and T-Mobile US. Even Arcep, the French regulator, now hints that it might allow consolidation in the French mobile market that it long has resisted.


Still, the U.S. Department of Justice said in 2011 that the transition from four to three mobile mobile providers in the U.S. would constitute an unacceptable reduction in the number of competitors.


That combination of AT&T and T-Mobile US would have raised market concentration scores on the Hirschman-Herfindahl Index (HHI) by more than 400 points, a level guaranteed to raise antitrust scrutiny.


Such a score is not an absolute barrier to any particular merger, but places a strong burden on the proponents to show why the merger is not anticompetitive.


Though what is the market? Is not a big question for regulators who will look at the Sprint merger with T-Mobile US, there are going to be bigger questions for some of the other possible mergers, starting with AT&T and Time Warner.

Such foundational questions about the relevant market also are likely to be an issue faced by regulators, if they look at market concentration in application markets lead by the likes of Google, Facebook and Amazon, in the future.
