The Measurement of Mobile Broadband Network Performance and Coverage

July 29, 2010
| Testimony and Filings

In comments filed with the FCC on The Measurement of Mobile Broadband Network Performance and Coverage, ITIF urges the FCC to rely on consumers to gauge the quality of mobile broadband. The FCC proposes to implement an elaborate system of measurement that's fraught with problems of fair sampling and timely reporting. As the typical FCC performance survey relies on data that's at least a year and a half old, and mobile networks are continually upgraded, the preferred system of measurement should stress timeliness over minute technical examination. Coverage maps are the most appropriate vehicle for mobile quality assessment, but they need to be accurate.

Looking for Trouble: The FCC’s Mobile Competition Report

June 2, 2010
| Reports

The FCC's Summer 2010 report on the state of mobile competition in the U.S. fails to appreciate just how competitive the marketplace actually is.


On the face of it, the market for mobile network services in the United States appears healthy: we're first to get the latest smart phones and all the applications they enable; we pay the lowest price per minute for cell calls in the world; and we have more meaningful choice among providers than any other country. You'd be hard-pressed to convince the typical American that he would be better off ditching his iPhone or her Droid in favor of one of the Nokias that Europeans pay three times as much per minute to use. While everyone would prefer a lower bill and even more choice among handsets and applications, by the global standard the U. S. is in excellent shape.

Or so you might think. But according to the FCC's recent Mobile Competition Report, trouble is brewing in the United States unless regulators take control of policy levers to alter the shape of our mobile marketplace. The Commission expresses a number of concerns about the future market, based in indications of increasing market concentration, decreasing network investment, and increasing profitability among major operators. Let's examine these issues one at a time.

Market Concentration

The FCC uses the standard Herfindahl-Hirschman Index (HHI) to measure market concentration. The mobile network market, like its sister market for wireline broadband, is characterized by high costs for infrastructure relative to operations expense. In other words, fixed costs are high and marginal costs low. These kinds of markets don't easily support the level of competition that we find in less capital intensive markets such as those for professional services or banking, for example. In fact, a strong case can be made that more competitors would lead to higher overall industry costs and therefore higher prices for consumers. Therefore, the question that has to be asked about market concentration is how to benchmark the HHI number (which the FCC puts at 2,848 out of 10,000.) There are two ways to do this, one historical and the other comparative.

Historically, HHI increased (higher numbers mean more concentration; a market equally divided among four firms has an HHI of 2500, one divided among three is 3333, and so on) between 2003 and 2005, decreased between 2005 and 2007, and increased again in 2008; it now stands higher than it has been in the last five years.

The reason for the recent increase in HHI is increased numbers of subscribers by AT&T, Verizon, and T-Mobile alongside a corresponding decrease by Sprint. The FCC’s chart illustrates recent history.

Figure 1: Average Herfindahl-Hirschman Index (source: Annual Report and Analysis of Competitive Market Conditions With Respect to Mobile Wireless, Including Commercial Mobile Services, FCC, May 20, 2010.)

The chart illustrates that a post-2005 trend toward reduced concentration and increased competition was disrupted in 2008, the year Apple opened the iPhone app store. AT&T gained market share very rapidly in 2008 thanks to its exclusive arrangement to market the iPhone, while competitors didn’t have a credible alternative until 2009, when Google launched its Android platform, Palm debuted the so far less-than-successful Pre and Microsoft updated Windows Mobile. The rise of Android in particular and multiple App Stores in general have radically altered the nature of the market for mobile networks and applications since 2008, but the FCC’s report unfortunately doesn’t capture these recent effects on market concentration, despite its use of recent data in other parts of its report.

A comparative analysis of the U. S. HHI views it in the international perspective, the familiar method that we apply to wireline broadband when criticizing the price and speed of American offerings against those in Korea, Japan, and Sweden that have been built with government support. The FCC report cites international HHI data drawn from a Merril Lynch study using a different benchmark. These data are presented in Table 1 following.

Table 1: Mobile Market Structure in Selected Countries (source: Merrill Lynch Calculation cited in p. 197 of FCC report.)

By the international standard, the U. S. is clearly in good shape; only one comparable nation, the U. K., had more major competitors in 2008, and two of them have subsequently merged, so no national market in the Merrill Lynch comparison is less concentrated than the U. S. Clearly, there’s not much source for anguish about the U. S. position in the international mobile ranking. This is actually quite similar to intermodal wireline broadband rankings, in which the U.S. and Canada lead the world.

Decreased Investment

The FCC expresses concern about a decreasing level of ongoing investment in network infrastructure relative to market size. Depending on which source of data one selects for ongoing investment (the choices are $20B/year or $25B), the growth in market size (e.g., sales) dilutes the ratio of investment to revenues from 20% to as little as 14% from 2005 to 2008. However, despite the decreased level of investment, FCC data indicates network operators added cell sites at a faster rate in 2008 than in the previous five years (see Figure 2.) Doing more with less is a good skill to display in the bad economy of recent years, and it also naturally follows that operators should invest more in networks during generational upgrades than at other times; 2008 was a transition year between 3G and 4G upgrades.

Figure 2: Incremental Cell Sites (source: FCC report)

Investment in new cell sites is one way of improving cellular network coverage, but there are others. During the period in which the FCC sees decreased investment relative to revenues, the major cellular operators added significant numbers of cell site by acquiring smaller networks, often at great cost. Verizon acquired Alltel for an aggregate transaction value of $28.1 billion, AT&T acquired Centennial for approximately $945 million, T-Mobile acquired Suncom for $2.4 billion, and Sprint invested in the Clearwire 4G network as a partner. Network expansion generally follows subscriber growth, and is therefore unlikely to follow a neat curve year after year. At the outset of 2008, the Verizon network was more extensive than the AT&T network (formed in large part by the acquisition of Cingular) and during the year, Verizon didn’t add subscribers as rapidly as AT&T. Therefore, Verizon’s operating conditions didn’t justify the same level of investment as AT&T’s in that particular year; the figures for 2010 are likely to be substantially different thanks to the uptake of Android devices and the roll out of 4G networks.

Moreover, the FCC’s investment figures unfortunately omit the $19.6 billion mobile operators spent in 2008 to acquire licenses in the 700 MHz spectrum auction. Simply adding auction costs to the cited investment figures doubles total investment independent of merger and acquisition expenses and would mean that overall investment actually increased quite substantially. There is also no conceptual difference between a carrier buying cell towers and buying the spectrum that enables them to utilize these towers. The omission of auction expenses from the report’s investment analysis leads to a faulty conclusion.

Excess Profitability

The Commission’s report seems to suggest that some operators are earning excess profits. It devises a profitability metric based on gross earnings (EBITDA) minus capital expenditures (CAPEX) per subscriber.

Figure 3: EBITDA minus CAPEX per Subscriber per Month (Selected Providers) (source: FCC report)

According to this calculation, two major operators are increasing profitability while two are decreasing. Perhaps coincidentally, CDMA operators (Sprint and Verizon) are more profitable than GSM operators (AT&T and T-Mobile.) This result would be expected during the transition from 2.5G to 3G technology, however, as CDMA has a less expensive upgrade path than GSM. GSM requires hardware upgrades to accomplish a feat that CDMA does with a software upgrade. This factor is important at generational upgrade points such as the one that began in 2007 relative to 3G and can influence relative rates of profitability since overall prices are set by markets but costs temporarily differ.

In terms of gross profits, network operators generally come in well below large Internet services companies: AT&T’s gross margin is 17.68%, while Google’s is 35.78%, for example. By the relevant standards for network businesses, the mobile operators aren’t earning excessive returns. Moreover, a key question to ask is not just if profits are “excessive” but what level of profitability mobile operators need to produce in order to maintain the capacity to invest continually in technology upgrades. If extreme competition reduces prices modestly but raises overall industry costs (as is likely to occur in industries with high fixed and low marginal costs), consumers might actually be worse off as upgrades would be more slow to come and less evenly distributed. In this case, society as a whole would be worse off as total economic welfare would be reduced by duplicate efforts in advertising and customer acquisition at the expense of technology investment..


A number of critics have expressed displeasure at the FCC’s lack of willingness to declare the mobile marketplace “competitive,” to which the Commission replies that it sought to offer a deeper analysis than the rather simplistic one that its predecessor offered year after year. The Commission is on solid ground in terms of its aspirations, but it’s difficult to regard this report as a success: important data are missing, the analysis is often superficial, and much of the data is too old to be fully enlightening. Mobile is a dynamic, rapidly changing marketplace, and 2008 conditions have little importance to “policy lever operators” working in 2010. In 2008, we were at the end of the 3G transition, but we’re now at the beginning of a 4G rollout. In 2008, Apple had the only significant App Store, but now each platform has one. Networks that were over-built and under-populated in 2008 are now gaining subscribers at a rapid rate, and two new mobile platforms will debut this year.

Perhaps most disturbing is the FCC’s disregard for the changes in the dynamics of the mobile marketplace itself. Five years ago, mobile devices were simple and network operators competed on the basis of price and coverage. With the advent of the smart phone, it also became important for the operator to offer the most attractive platform and the best data handling capability, and at present applications have become increasingly important. So the number of operators and their systems of base stations, backhaul, and spectrum no longer determines the competitiveness of the mobile marketplace; it’s also a matter of applications, App Stores, and their policies . Consumers benefit as much from competition between Apple’s iPhone, Google’s Android, RIM’s Blackberry, Hewlett-Packard’s Pre, and Microsoft’s Windows Mobile 7 as they do from competition among network operators.

It’s difficult for an agency with as much history as the FCC to break from the past and take a more holistic view of the markets it regulates, so we should appreciate the attempt to offer a non-traditional analysis of the mobile marketplace. We hope that the next edition will be more comprehensive and up-to-date.

The Internet is changing. In a few short years, Internet use will come predominately from mobile devices such as smart phones and tablets rather than traditional PCs using fixed broadband. A fully mobile broadband Internet offers exciting opportunities for innovation in networks, devices, and applications with enormous benefits for the economy and society.

The shift from a wire-centric Internet to a mobile one has profound implications for technology, policy, and applications. A new report by ITIF Research Fellow Richard Bennett explains how mobile networks are changing as they become part of the Internet, the implications mobile networking has for public policy, and how policymakers can facilitate the flowering of the mobile Internet. This will only come to pass, however, when engineering and policy collaborate to successfully overcome the challenges to the development of a Mobile Internet that lives up to its full potential. For this to happen, policymakers must do two key things: First, they need to refrain from strangling the Mobile Internet with excessive regulation, realizing that the well of innovation that brought us where we are has not run dry. Second, policy makers need to ensure that the mobile Internet can develop the infrastructure it needs, the most important part of which is spectrum. Policymakers need to make tough choices, transferring spectrum from less compelling historical uses to the emerging Mobile Internet.

While the technology is readily available in the U.S., it will be some time before Americans can use their cellphones as mobile wallets.

Imagine being able to use your mobile phone to pay taxi and mass transit fare; use vending machines; make retail purchases; and check in at hotels. Every day, millions of citizens in Japan, S. Korea, and soon Singapore do so simply by waving their mobile phones in front of point-of-sale terminals using near-field communication or related technology. But, while the technology is readily available in the U.S., it will be some time before Americans can use their cellphones as mobile wallets.
