CBRS is "Mobile Plus" Spectrum

As U.S. auctions of 3.5-GHz Citizens Broadband Radio Service have gone through 47 rounds of bidding, we now have a better idea of buyer estimation of the value of priority access licenses. To wit, those PAL licenses already are valued very close to 2-GHz mobile spectrum, and the auctions are not over yet..

At a high level, that suggests buyers see CBRS has having as much value as 2-GHz mobile spectrum. And, as was the case for the early 2-GHz spectrum awards, that is the ticket to market entry on a facilities basis for new competitors. Both Sprint and what became T-Mobile US were launched on the basis of new 2-GHz spectrum allotments. 

CBRS also will be supported by best effort spectrum access without a license, on the pattern of Wi-Fi. How big a revenue opportunity that activity might create is another question. Some internet service providers will undoubtedly explore the use of unlicensed CBRS to support rural internet access. That is something many wireless ISPs have done before.

But CBRS also is expected to support at least some private networks as well. Such private networks offer value to users and operators, but no often no direct revenue upside for the network operator.

Of course, there are many in the value chain who are not in the "connectivity as a service" role. All such private networks will create demand for infrastructure, maintenance, upgrades, design, perhaps connectivity and other services supporting other parts of the ecosystem. Consider radio instrastructure.

A 2019 report on the indoor market opportunity for CBRS, from Maravedis and EJL Research predicted that the CBRS radio node market will grow from revenues of about $3 million to $100 million by 2024, “driven primarily by private LTE deployments.” Keep in mind that is a prediction about mobile-type radio infrastructure used to support indoor market communications. 

Other estimates of CBRS radio capex illustrate the fact that--interesting as it is for some parts of the ecosystem--CBRS represents a very-small percentage of total mobile radio spending. According to Mobile Experts, CBRS CBRS radio infrastructure spending will not hit $1 billion in annual spending for five years or so. 

That makes CBRS an interesting and important market for some, not for all, on a global level.

Other parts of the CBRS value chain represent various amounts of new sales activity as well, but it might be fair to note that many opportunities which are transformative or important for some suppliers (access system administrators, infrastructure, software, integration and consulting) might not prove especially large for connectivity service providers.

The value of CBRS obviously is a non-zero number, though, and the value often will come in the form of avoided cost, not direct incremental revenue. Cable TV operators are expected to benefit primarily from avoided mobile wholesale capacity costs.

Some internet service providers, though, may be able to use CBRS to support their internet access businesses, using CBRS for fixed wireless access. System integrators, network designers and consultants might in some cases see meaningful revenue upside as well. 

Of course, not all CBRS spectrum will likely be used using PAL. As with Wi-Fi, CBRS spectrum also includes “best effort” access without a license. For some use cases, best effort access might be sufficient, especially for many private networks. 

Also possible are many collaborative ventures where a PAL license holder might be willing to allow use of its license for a big private network, in some business arrangement. That might be interesting for large areas such as port facilities where a mobile operator can expect little financial return for providing direct service. 

In some cases, some apps or use cases might benefit from licensed access with less risk of signal interference and therefore unpredictable or less predictable performance. Collaborative networks (private on the premises but connected to the public network; private network but with rights to use PAL on the site; private network built and maintained by a public provider) might make sense in those cases. 

The point is that the new commercial value of CBRS networks will have a wider range of value drivers than has been typical for mobile spectrum.

Second Law of Motion, Second Law of Thermodynamics Provide Key Business Analogies

Newton's second law of motion explains that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. 

A corollary of sorts is that “friction” is an uncorrelated or unbalanced force. In other words, friction always acts in the direction opposing motion. 

If friction is present, it counteracts and cancels some of the force causing the motion when any object is being accelerated. That means a reduced net force and a smaller acceleration. 

In this illustration Fa is the intended force, but faces uncorrelated forces including gravity and friction that essentially resist the applied force.

And that is a similar concept to the idea of friction in business and life. No matter what resources are mobilized in pursuit of some objective, friction will reduce yield, effectiveness and impact. All organizational effort therefore must overcome friction. That is true for capital investment, competition, operating procedures, product development and production, distribution channels and customer support and service, plus marketing and legal or regulatory tasks. 

Virtually every business activity therefore involves some element of overcoming friction, which is the resistance to desired change or outcomes. 

As an energy conversion is somewhat inefficient, producing unwanted heat in addition to desired energy output, so friction prevents full and complete application of resources to any process. 

Friction is akin to the Second Law of Thermodynamics, which states that disorder (entropy) increases over time. In other words, order proceeds to disorder. So much organizational effort must be devoted to preventing entropy (decay). 

That is why all efforts to create a more frictionless business is an unstated objective of virtually all organizational activities.

Newtonian Technology Trends Post-Covid

Twenty years ago, futurist John Naisbitt wrote High Tech/High Touch, an examination of technology and a follow-on to his 1982 book Megatrends. It was Megatrends which predicted that people immersed in technology would be driven to seek human contact. 

High Tech/High Touch essentially concluded that the trend remains intact, shown in the prominence of both consumer technology markets and products, services and markets that offer escape from technology.

As the Covid-19 pandemic wears on, increasing our reliance on technology and restricting human contact, Naisbitt’s observations still hold. The more we are now forced to use technology, the more important will actual “high touch” matter.

It is almost Newtonian: for every action there is an equal and opposite reaction. Kept indoors, demand for outdoor activities has grown significantly. Forced not to travel, people will want to travel. Required to interact virtually, people will want face-to-face encounters. 

The conventional wisdom that “everything has changed” suggests disruptive change in work and living habits that are permanent. That likely will prove to be a one-sided analysis. 

Post-pandemic behavior might be more unexpected than is commonly suspected, for several reasons. First, linear extrapolation from the present nearly always proves wrong. Non-linear change is more likely, an argument the “everything has changed” view also suggests.

But non-linearity cuts both ways. We might well see non-linear regression to the mean, as well as accelerated change of behavior. 

Many trends that already were underway before the pandemic  will be accelerated to an extent, though not nearly so much as many seem to believe. Naisbitt’s observations suggest why: to the extent we continue to work remotely, more often, we also are going to want and desire face-to-face contact. Unable to freely travel, humans will want to do so again. 

Zoom is not a perfect, or nearly perfect substitute for face-to-face interactions. People will want to get away from their screens, to the extent they are forced to rely on them. 

The Newtonian reaction to high tech will be high touch. 

Why the Broadband "Problem" Cannot be Permanently "Solved"

 So long as we keep changing the definition of “broadband,” we are likely “never” to see “improvement” in the number or percentage of homes or people able to buy the product, no matter how much investment is made in facilities. 

When we change definitions of minimum speed, for example, we automatically increase the number or percentage of locations or people that cannot buy the product. Colloquially, that is known as “moving the goalposts.” Put another way, our understanding of “broadband” changes over time. 

The classic definition of broadband was that it was any service running at speeds of 1.5 Mbps. In the U.S. market the official definition of “broadband” is 25 Mbps. But most consumers buy service at speeds an order of magnitude higher than the minimum definition. Yesterday’s power user is today’s light user.

And though new platforms might help, a continuing evolution of our definitions to support an increase in minimum speeds will continue to be a challenge for any market or country with lots of rural or thinly-populated areas. In the United States, six percent of the land mass is where most of the people live. 

How we define the market also affects our analysis of the amount of competition in the consumer broadband market. The common observation in the U.S. market, for example, is that minimum service at 25 Mbps is unavailable to “millions” of people. 

Of course, that finding requires a big assumption, namely that all satellite and mobile services are excluded from the analysis. Two U.S. satellite suppliers sell broadband access across virtually the entire continental land mass, while mobile speeds already exceeded the minimum threshold in 2019 and early 2020. 

If any and all services supplying 25 Mbps or faster speeds are considered, it might be very difficult to find any U.S. locations unserved by at least two providers. 

The point is that definitions and assumptions matter. By continually increasing the speed used as the definition of “broadband,” we will almost arbitrarily keep moving the goal line on who has it, where it is available and how many competitors can sell it. 

Ignore for the moment consumer choice, which has shown that most consumers buy services in the middle of the range: not the most costly or least costly; not the fastest or slowest offerings. 

Because “typical, average or median speeds” will keep getting higher, so will our definitions be adjusted. But at a time when satellite and mobile minimum and average speeds often already exceed the minimum definitions, and where most fixed network consumers buy services an order of magnitude above the “minimum” threshold, it is hard to “close the digital divide.”

There likely will always be some statistical gaps. Where there is a serious “problem” actually is--or will be--more debatable.

5G Is Not the Issue Anymore

 It increasingly is impossible to clearly delineate the value, strategic or revenue potential of 5G separately from the other companion developments that create value, strategic potential and incremental revenue. 

Consider edge computing and 5G for consumer mobile devices. Most observers now would agree that internet access, supplied by connectivity providers, is part of the broader internet ecosystem. Likewise, most of the growing use cases and revenue drivers depend on connectivity, but are not directly “owned” by connectivity providers.

That is the basic reason behind the interest, in some cases, in connectivity provider ownership and participation in adjacent parts of the ecosystem (applications, real estate, platform), beyond connectivity. 

By 2028, 4G and 5G mobile consumer and residential consumer applications will dominate the edge computing footprint, for example, says the State of the Edge 2020 report. A growing number of those apps would not be consumable without edge computing plus the latency performance and bandwidth made possible by 5G. 

source: State of the Edge 202

The edge computing power footprint for mobile and residential consumers will reach 16938 megawatts and 10843 MW, respectively by 2028, the report says. 

Edge computing power footprints for service providers and enterprise IT is expected to increase 7117 MW and 5800 MW, respectively.

Mobile operators especially will be significant users of edge computing to support their own internal operations, including their virtualized 5G core and access network facilities.

U.S. Gigabit Accounts Near 5%

 About five percent of U.S. fixed network internet access lines (also including business lines) in the second quarter of 2020 reached almost five percent, according to Openvault, up from 2.1 percent in the second quarter of 2019, and up from 3.75 percent in the first quarter of 2020.

6% of U.S. Land Mass is Where Most of the People Are

One oft-ignored facet of communication network economics is that the business model is helped when population density is high, and generally suffers when population density is low. Also, it is far easier to build a whole new network in a small area, compared to a continental land mass. 

About six percent of the U.S. land mass is “developed” and relatively highly populated. About 94 percent is unsettled or lightly populated, including mountains, rangeland, cropland and forests.

Pastures are located largely east of the hundredth meridian.

Croplands, at least at the moment, stretch a bit further west.

Rangelands mostly are found in the West.

But even the higher-population areas east of the Mississippi River contain huge tracts of forest land.

All those facts have implications for networks. Most of the population or potential users can be covered by a smaller amount of network infrastructure, at first. But network coverage is another matter, as 94 percent of the land surface is lightly populated, consisting of forests, mountains or range land. 

In just about any instance, in any market, though, 80 percent of the revenue might be generated by 20 percent of the accounts, locations or use cases. Ericsson studies show that just 30 percent of cell sites support 75 percent of all traffic on the network. 

So it should come as no surprise that the cost of rural infrastructure can be an order of magnitude higher than for denser urban infrastructure.
