Spatial data constraints: Implications for measuring broadband

The accurate determination of where broadband telecommunication services are available in the United States continues to be a significant challenge. Existing data regarding broadband provision, such as that provided by the Federal Communication Commission (FCC) simply designate ZIP codes with at least one high-speed Internet subscriber. As ZIP code areas vary greatly in size and shape, the lack of geographic specificity as to exactly where broadband is available, particularly within ZIP code areas, confounds communications policymaking. Further, there are a number of additional geographic nuances concerning broadband availability that also inhibit empirical examination and policy generation, including the spatial limitations of digital subscriber line services. The purpose of this paper is to briefly review the issues concerning broadband measurement in the United States and provide an empirical analysis of several spatial data constraints that must be accounted for when interpreting and constructing public telecommunications policy.     

Closing information asymmetries: A scale agnostic approach for exploring equity implications of broadband provision

A persistent challenge for telecommunications policy is the determination of broadband provision footprints in both space and time. In the United States, Form 477 data from the Federal Communications Commission (FCC) provide a valuable snapshot of broadband provision at the block level, but there are often inconsistencies with the underlying data. These inconsistencies include overly-optimistic self-reports from providers, requirements to report broadband provision within inflexible census administrative units, and a modest temporal reporting schedule (biannual) with a significant, one year temporal lag. These uncertainties are often compounded by telecommunications providers refusing to disclose any information on service footprints, geographic expansion plans or the characteristics of populations served by broadband. This type of obfuscation drastically limits the ability of policy analysts to evaluate outcomes (both positive and negative) associated with service provision and the digital divide, more generally. With the recent entry of Google Fiber to several metropolitan markets in the United States, many of the broadband reporting and evaluation challenges have re-emerged. The purpose of this paper is to leverage basic data mining techniques, a scale agnostic geographic framework and exploratory spatial data analysis (ESDA), to uncover the geographic intricacies of Google Fiber (Fiber) service for both Provo, Utah and Austin, Texas and compare them to Form 477 reports. In addition, we use basic statistical approaches to explore issues of broadband access and equity, accounting for the differences in socio-economic and demographic status of the populace served/not served for both cities, as well as basic pricing within and between communities.     

Efficiency in broadband service provision: A spatial analysis

With the 2008 Federal Communications Commission (FCC) order amending both the definition of broadband and its data collection practices, the problems associated with data integrity and ZIP code aggregations in the United States will soon be forgotten. However, between 1999 and 2007, FCC Form 477 data remain the only viable, nationwide database of broadband provision in the United States. While broadband data from 1999–2004 and 2005–2007 are not directly comparable due to a modification in collection procedure, there is an absence of objective empirical analysis for the latter time period. Interestingly, although the FCC made the 2005–2007 data publically available on the Internet, password protected files largely prevented analysts from accessing, manipulating and analyzing these data. The purpose of this paper is three-fold. First, the process utilized for liberating these data from their protected format and integrating them into a geographic information system (GIS) is outlined. Second, the spatial distribution of broadband provision in the United States for 2005–2007 is explored. A mathematical programming approach is also utilized for comparing the relative efficiencies of ZIP code areas in acquiring broadband service given their demand-side socio-economic and demographic determinants. Finally, implications for public policy, particularly those associated with developing local and regional benchmarks for broadband provision, competition and access, are addressed.     

A preview of the broadband fabric: Opportunities and issues for researchers and policymakers

The Broadband Deployment Accuracy and Technological Availability (DATA) Act signed into law in March 2020 requires the development of a national “broadband serviceable location fabric (BSLF)” containing georeferenced information on all locations where fixed broadband could be installed. This represents a significant shift from prior datasets, where broadband availability was gauged from the estimated number of people/households in each Census Block (i.e., without geolocations). The inclusion of agricultural structures is particularly important, since broadband investment in agricultural zones has been limited to date. We use an early version of the BSLF for the state of Oklahoma, produced by CostQuest Associates, to demonstrate the opportunities and issues that may arise for broadband researchers and policymakers as the DATA Act becomes reality. We highlight four main takeaways: (1) consideration of non-residential units greatly impacts overall availability estimates; (2) data quality (and quantity) varies greatly across counties; (3) BSLF residential unit counts differ from FCC or Census estimates; and (4) practitioners will still need service-area shapefiles/addresses from providers to use the fabric most effectively.     

Broadband speed and unemployment rates: Data and measurement issues

We examine the effects of broadband speed on county unemployment rates in the U.S. state of Tennessee. We merge the older National Broadband Map dataset and the newer FCC dataset in lengthening our broadband access data over the period 2011–2015. Extending the dataset improves the precision of the estimates. Our panel regressions control for potential selection bias and reverse causality and show that broadband speed matters: unemployment rates are about 0.26 percentage points lower in counties with high speeds compared to counties with low speeds. Ultra-high speed broadband also appears to reduce unemployment rates; however, we are unable to distinguish between the effects of high and ultra-high speed broadband. We document beneficial effects of the early adoption of high speed broadband on unemployment rates. Better quality broadband appears to have a disproportionately greater effect in rural areas.     

Estimating willingness-to-pay for broadband attributes among low-income consumers: Results from two FCC lifeline pilot projects

Recent studies have confirmed that broadband adoption (as opposed to simply having access to broadband infrastructure) is positively linked with economic growth. In light of this, federal policy efforts have switched from focusing mainly on the provision of infrastructure to more explicit adoption-oriented efforts. One of those efforts was the Federal Communications Commission’s (FCC’s) Low-income Broadband Lifeline Pilot Projects, which ran from 2013 to 2014. The program worked with 14 private telecommunications firms to subsidize household broadband adoption for low-income households by providing discounted monthly and equipment costs. Low-income households are an important component of the broadband adoption puzzle: between 2003 and 2013, the adoption gap between low-income and high-income households actually increased by 5% points. This paper focuses on two specific FCC Broadband Lifeline Pilot projects that allowed consumers to make choices among different options, such as data allowance, speed, and wireless vs. wired connections. Conditional logit models are used to develop estimates of consumer’s willingness-to-pay for specific broadband attributes. The results indicate that low-income consumers have a preference for smartphone connections (versus aircards) – and that this effect is even more pronounced for those households earning less than $20,000; that low-income consumers have a preference for wired connections (versus wireless); and that there is evidence that low-income consumers are willing to pay for an extra GB of data each month – but not for the speed of their connection.     

Socio-spatial patterns of the national broadband network revealed: Lessons from greater Sydney,Melbourne, and Brisbane

The National Broadband Network (NBN) is the largest public infrastructure project in the history of Australia. The goal of the NBN is to provide Australians with broadband internet access by using a mix of technologies, ranging from fibre and hybrid fibre-coaxial to fixed wireless and satellite platforms. Although the NBN is a public project, one of the more vexing aspects of its evolution is its lack of data transparency. There is virtually no information on platform use or footprint distribution throughout the country. Not only does this drastically limit evidence-based telecommunications policy analysis, it also limits the ability to evaluate equity in the spatial distribution of broadband connectivity and infrastructure quality. The purpose of this paper is to uncover the geographic presence of the various NBN technologies using data mining techniques and census-based socio-spatial data (SEIFA). The results portray the complexity of the NBN footprint across three metropolitan regions of Sydney, Melbourne, and Brisbane – with a focus on how the mixed-technology platform adopted divides major Australian cities.     

Broadband׳s contribution to economic growth in rural areas: Moving towards a causal relationship

This paper uses recent data on both broadband availability and adoption to empirically gauge the contribution of broadband to the economic growth of rural areas of the United States over the past decade. Availability data from the National Broadband Map aggregated to county level is used in conjunction with county-level adoption data from Federal Communication Commission. Economic variables of interest include median household income, number of firms with paid employees, total employed, percentage in poverty, and the percentage of employees classified as either creative class or non-farm proprietors. A propensity score matching technique (between a “treated” group associated with various broadband thresholds and a control group) is used to make preliminary causal statements regarding broadband and economic health. Growth rates between 2001 and 2010 for different economic measures are tested for statistical differences between the treated and non-treated groups, restricting the analysis to non-metropolitan counties. Results suggest that high levels of broadband adoption in rural areas positively (and potentially causally) impacted income growth between 2001 and 2010, and negatively influenced unemployment growth. Similarly, low levels of broadband adoption in rural areas lead to declines in the number of firms and total employment numbers in the county. Broadband availability measures (as opposed to adoption) demonstrate only limited impacts, suggesting that future broadband policies should be more demand-oriented.     

The spatial distribution of broadband providers in the United States: 1999–2004

Variations in the supply and demand of telecommunications infrastructure in the United States are well documented. However, amidst waning concerns of a broadband digital divide, the geographic aspects of broadband availability continue to be intriguing. While some areas benefit from a robust selection of broadband providers, choices for consumers in other regions are often limited. The purpose of this paper is to explore the spatially unbalanced levels of broadband provision in the USA by providing an abbreviated longitudinal analysis of broadband regions and their development from 1999 to 2004. Broadband core and periphery regions are identified through the use of spatial statistical techniques and a geographic information system. A broadband competition index for ranking metropolitan and micropolitan areas is also introduced.     

Broadband infrastructure and export growth

With the digital transformation of the economy and society, high-speed Internet is becoming an important supporting infrastructure for international trade activities. This study treats the pilot policy of the Broadband China strategy as a quasi-natural experiment and investigates the ways in which broadband infrastructure development affects export trade in Chinese cities. Empirical results show that export trade in the pilot cities increases by 6.82%–18.8% on average as a result of the Broadband China policy intervention. Our study shows that this policy can effectively promote the use of Internet facilities, and broadband infrastructure can significantly promote the growth of a city's export trade. Broadband infrastructure influences export trade through the direct channel of improving information efficiency, which in turn lowers logistics costs, promotes trade efficiency, and reduces barriers to trade. There is no significant regional heterogeneity and urban characteristics heterogeneity in the export trade effect. Although broadband infrastructure can affect exports through the indirect channels of industrial structure and technological innovation, the direct effect accounts for much of the total effect.     

State broadband policy: Impacts on availability

We use a county-level panel dataset from 2012 to 2018 to assess the impacts of various state policies on total and rural broadband availability in the United States. The primary dependent variable is the percentage of residents with access to 25 Megabits per second (MBPS) download and 3 MBPS upload speeds via a fixed connection, with alternative specifications considering other aspects of availability such as technology type and competition. We control for the main determinants of Internet availability such as income, education, age, and population density. Our policy variables come from the newly released State Broadband Policy Explorer from the Pew Charitable Trusts and individual contacts from the nationwide State Broadband Leaders Network. Our primary policies of interest are those related to: (1) availability of state-level funding, (2) existence of a state-level broadband office/task force with full-time employees, and (3) restrictions on municipal/cooperative broadband provision. We find a positive and significant impact of state-level funding programs on general (and fiber) broadband availability, and a negative impact of municipal/cooperative restrictions. The findings are similar when the analysis is restricted to the rural portions of counties.     

Implementing policy on next-generation broadband networks and implications for equity of access to high speed broadband: A case study of Australia's NBN

Next generation telecommunications infrastructure is expanding and supporting rapid growth of broadband technologies and a digital economy. In this context, digital information and communications technologies (ICTs) are of increasing importance as a means for people to gain access to health or social services, employment opportunities, information and social networks. In this article we draw on our recent case study research to examine the policy (and politics) shaping implementation of Australia's National Broadband Network (NBN) and its likely effects on equity of access to high speed broadband (HSB) services. We monitored NBN policy and implementation from 2015 to 2018 through policy documents, reports, and media. To assess likely effects of NBN policy on implementation and subsequently on equity of access to HSB we: a) applied a framework defining four elements of equity of access; and b) analysed stakeholder views drawn from media articles and 22 interviews with experts on NBN policy including politicians, government staff, and industry representatives. We found that equity considerations competed with political and commercial imperatives during the rollout of the NBN. This resulted in positive and negative consequences for equity of access to HSB, with a change in policy and implementation in 2013 bringing greater risks to equity of access. The case study provides a framework for considering equity in the implementation of next generation telecommunications infrastructure and highlights the importance of considering equity in the evaluation of telecommunications infrastructure.     

An econometric approach for evaluating the linkages between broadband and knowledge intensive firms

In addition to highlighting improvements in the availability and speed of broadband as a national priority, the National Broadband Plan also includes several recommendations for improving access and use of broadband by small businesses. The plan also recommends economic development officials include broadband in their local development strategies. While these are certainly import goals, more research is needed to evaluate how broadband impacts the regional business environment, and regional capacity to retain and attract businesses in particular industries. In order to further our understanding about the linkages between broadband and businesses, and the ability of places to retain and attract businesses in particular industries, this study will develop and estimate econometric models to better understand the linkages between broadband and firms in the knowledge intensive sector. Specifically, 54 metropolitan area specific models will be developed to examine regional variations in the linkages between broadband and firms in the knowledge intensive sector in 2004. Model results highlight the importance of broadband to knowledge firms in all but five metropolitan areas across the U.S. They also reveal variations in the impact of broadband on knowledge firm presence related to metropolitan area size and industrial legacy.     

A longitudinal analysis of broadband provision in tribal areas

While disparities in broadband in rural areas are well documented, little research exists about broadband in tribal communities. This gap means we lack information about the trajectory of broadband deployment in tribal areas. It also means we lack comparative information about the similarities or differences in the trajectory of broadband deployment in tribal areas compared to non-tribal areas (e.g. urban and rural areas). To address this gap in our knowledge, this study utilizes longitudinal tract data constructed from information in the FCC Form 477 database to analyze broadband provision in tribal areas from 2014 to 2020. Empirical results show that rural tribes may be falling further behind the rest of the nation in broadband provision, while metropolitan tribal areas now enjoy better provision levels, on average, than their non-tribal counterparts. Additionally, the nuances of broadband distributions across tribal, rural, and urban areas make clear that a one-size-fits-all policy to aid tribal communities is inappropriate to address these and other related challenges. This is especially true as concerns about the intersection of federal broadband policy with tribal sovereignty and self-determination emerge.     

Impacts of the Broadband Initiatives Program on broadband adoption and home telework

This study investigates the impacts of the Broadband Initiatives Program (BIP), established by the American Recovery and Reinvestment Act in 2009, on growth in broadband adoption and use of home telework. We find robust positive impacts across multiple econometric models and methods using census tract-level data in first differences. Across models and methods, the estimated average impact of BIP is in the range of 1.1–3.0 percentage point increase in the share of households adopting broadband and 0.2 to 0.4 percentage point increase in the share of workers using home telework. The estimated impacts of BIP represent roughly one-fourth to two-thirds of the average increase in broadband adoption and one-third to two-thirds of the average increase in home telework in the study tracts during the study period. The impacts of BIP vary across geographic contexts. Broadband and home telework adoption are also affected by prior levels of broadband availability, adoption, and telework, and by demographic and socioeconomic characteristics of the population and the industrial structure of the economy.     

The involvement of utilities in the development of broadband infrastructure: A comparison of EU case studies

Energy companies and other utility providers have been often involved in the provision of telecommunications services. Nevertheless, their contribution to broadband development has varied significantly over time. In the late 1990s, both local and national utilities in the European Union (EU) engaged in the provision of broadband networks, but only few of them managed to establish themselves as major broadband providers. More recently, new projects involving national utilities have been announced in several EU countries, opening new scenarios for utilities’ contribution to Next Generation Access (NGA) development. This paper identifies and explores the factors affecting the entry and the success of utilities in the EU broadband market, through the comparison of four case studies from four EU countries (Germany, Italy, Sweden and the UK). The evolution of utility involvement in the EU broadband markets is assessed against the interaction of market, technology and policy factors, focusing on the impact of policy and regulatory measures. As a result, this paper provides fruitful insights into the relevance and effectiveness of public interventions in broadband markets. Across the four case studies, public support and public ownership emerged as the main drivers for the involvement of utilities in EU broadband markets, with regulatory measures and economies of scope exerting a limited and decreasing influence. However, the contribution of utilities has varied significantly across the cases studied, reflecting the different approaches taken at national and local level to support broadband development, in spite of the common regulatory framework.     

Socio-technical analysis of Korea's broadband convergence network: Big plans,big projects,big prospects?

The goal of this study is to investigate the policy objectives of the broadband convergence network (BcN) and the realization of objectives. The Korean government launched the BcN project with the objective of converting Korea into an information society with ubiquitous broadband convergence for the advancement of growth and productivity. Based on content analysis of the policy documents and the literature related to BcN, this paper draws on the socio-technical framework for interpreting the data. Findings in this study suggest that, despite excellent technological innovation and proactive drive, uncertainty still remains with respect to how the BcN has evolved and its impact on the new telecom ecology to date.     

Broadband achievement index: Moving beyond availability

High-speed access to the Internet enhances economic prosperity, social development and global competitiveness. Significant progress has been made in broadband deployment in the last decade. Nevertheless, there are increasing gaps in broadband adoption, use and speed between, as well as within, the states. Federal and state legislators and regulators currently use a number of indicators such as adoption, availability and speed to track states’ progress in broadband diffusion in order to design appropriate policy responses. Single indicators, however, when analyzed individually, fall short of capturing multi-dimensional aspects of broadband diffusion and, thus, do not provide an integrated and easily comprehensible picture of states’ advancement. To monitor states’ overall progress it is useful to aggregate various indicators into a composite index that could measure the overall extent of broadband diffusion. A composite index can also provide with an important benchmark for designing policies to improve states’ overall performance. This paper offers a flexible framework for benchmarking states’ achievement in broadband diffusion by proposing a composite Broadband Achievement Index (BAI). The index combines several key performance indicators: broadband availability, adoption, competition, speed and the dispersion of broadband adoption within the states utilizing FCC's Form 477 data and the recently collected census block level broadband availability data from NTIA. The purpose is to provide a more comprehensive picture of where the states stand in their evolution toward high-performance America by measuring each state's current broadband achievement relative to other states and providing an important benchmark for assessing state-specific needs. The indicators are combined using the Benefit of the Doubt (BOD) methodology (Cherchye, Moesen, & Van Puyenbroeck, 2004). The methodology is founded on the premise that, absent a consensus on social policy priorities, that are, on which indicators are more important and should be given higher weights in the index, each state is granted leeway for deciding how to weigh its own indicators and the most favorable weights for indicators are determined for each state. A good relative performance in a particular dimension is seen as revealed evidence of setting high state policy priority to that indicator, when each state's specific policy priorities are unknown. Additionally, the Second Order Stochastic Dominance (SOSD) methodology is used to compare the dispersion of adoption in the states. Using SOSD the states are ranked under the assumption that proportionally higher and more equally distributed adoption rates are better.
