Introduction

This chapter is contextual in nature. It provides an overview of the impact of COVID-19, highlighting both the significant number of deaths caused by the pandemic as well as the economic disruption that occurred. Particular attention is paid to the role of digital technologies during the pandemic, which enabled a wide range of activities (e.g. work, education and shopping) to go online. The disruptive impact of COVID-19 is widespread and far-reaching, with the pandemic acting as a 'change agent' expanding and encouraging the greater use of digital technologies. The second half of the chapter presents summaries of the other chapters in the book. In doing so, it illustrates the scope and scale of the impact of COVID-19, the multitude of different challenges it has caused, and how these varied across different regions and contexts, as well as the diversity of reactions to the pandemic. Some of these reactions are technical in nature, while others are commercial and political. The summaries also draw attention to ongoing policy debates, the significance of which has been heightened by the pandemic. © 2023 the authors.

Beyond the pandemic: Towards a digitally enabled society and economy

Besides the widespread harm and dreadful impact COVID-19 has caused, it brought about change. Interpreting the pandemic as a 'change agent', it is possible to observe how it accelerated the use of digital technologies, facilitating the migration of many activities to the virtual sphere and thus changing the interaction between the physical and virtual worlds. Although the pandemic accelerated the diffusion and adoption of digital technologies, allowing many to avoid or reduce the harms caused by the pandemic, not everyone benefitted to the same extent. The pandemic exacerbated existing digital divides while creating new ones, simultaneously elevating important policy debates regarding digital infrastructure and inclusion policies. © 2023 the authors.

COVID-19 and the internet: Lessons learned

The COVID-19 pandemic has disrupted the 'real' world and substantially impacted the virtual world and thus the Internet ecosystem. It has caused a significant exogenous shock that offers a wealth of natural experiments and produced new data about broadband, clouds, and the Internet in times of crisis. In this chapter, we characterise and evaluate the evolving impact of the global COVID-19 crisis on traffic patterns and loads and the impact of those on Internet performance from multiple perspectives. While we place a particular focus on deriving insights into how we can better respond to crises and better plan for the post-COVID-19 'new normal', we analyse the impact on and the responses by different actors of the Internet ecosystem across different jurisdictions. With a focus on the USA and Europe, we examine the responses of both public and private actors, with the latter including content and cloud providers, content delivery networks, and Internet service providers (ISPs). This chapter makes two contributions: first, we derive lessons learned for a future post-COVID-19 world to inform non-networking spheres and policy-making;second, the insights gained assist the networking community in better planning for the future. © 2023 the authors.

Net neutrality in the USA during COVID-19

The COVID-19 pandemic provides an opportunity to review net neutrality and the notion that bright light rules are necessary to hold broadband providers from exercising market power. The 2015 Federal Communications Commission (FCC) Open Internet Order asserted that broadband providers have the capability and incentive to harm their customers and third-party service providers. It imposed a set of rules to control broadband providers' offers, prices, and traffic management. The 2017 FCC vacated all but the transparency provisions of the OIO, restoring the oversight of broadband to the FTC. This paper offers a review of the evidence regarding the effects of net neutrality regulation, including an investigation of the incidence of violations, or lack thereof, during the 2020 pandemic in the United States. It provides a review of the net neutrality literature and the international research on broadband provider behaviour during COVID-19. The paper presents original research conducted with FCC and FTC reports and a survey of news stories. Brief reviews of federal data on network performance and broadband adoption provide additional context. Given the limited incidence of violations that could be uncovered for the period, the paper suggests why broadband providers behaved opposite to regulatory advocates' predictions. Contrary to many policy assertions, broadband providers did not block or throttle service, nor did they increase prices arbitrarily or decrease quality. Broadband providers appeared to expand availability, lower broadband prices, and make more networks available, frequently without customer charge. The paper suggests how policy could be updated to reflect the actual behaviour of broadband providers. © 2023 the authors.

Regulatory and broadband industry responses to COVID-19: Cases of Uganda, Peru, and the Caribbean

The COVID-19 pandemic was particularly challenging for developing countries because of pre-existing poverty and severe inequality. Governments tended to set public safety as a primary goal, but it could not be their singular goal. Broadband was an important feature of any policy solution. Business lockdowns, school closures, and social distancing led to an unprecedented acceleration in the demand for broadband. But the government restrictions on social and economic interactions made it difficult to maintain and expand broadband networks. Governments might have let markets work out this challenge of escalating demand and increasing costs of supply, but few did. Governments quickly grew to believe that it would need cooperative relationships among multiple government agencies and private businesses to answer what appeared to be a broadband shortage. Regulatory controls over broadband providers were quickly suspended in favour of developing common goals and coordinated efforts. These approaches proved effective, although citizens continued to suffer from the pandemic. © 2023 the authors.

Probing environmental and tectonic changes underneath Mexico City with the urban seismic field

The sediments underneath Mexico City have unique mechanical properties that give rise to strong site effects. We investigated temporal changes in the seismic velocity at strong-motion and broadband seismic stations throughout Mexico City, including sites with different geologic characteristics ranging from city center locations situated on lacustrine clay to hillside locations on volcanic bedrock. We used autocorrelations of urban seismic noise, enhanced by waveform clustering, to extract subtle seismic velocity changes by coda wave interferometry. We observed and modeled seasonal, co- and post-seismic changes, as well as a long-term linear trend in seismic velocity. Seasonal variations can be explained by self-consistent models of thermoelastic and poroelastic changes in the subsurface shear wave velocity. Overall, sites on lacustrine clay-rich sediments appear to be more sensitive to seasonal surface temperature changes, whereas sites on alluvial and volcaniclastic sediments and on bedrock are sensitive to precipitation. The 2017 Mw 7.1 Puebla and 2020 Mw 7.4 Oaxaca earthquakes both caused a clear drop in seismic velocity, followed by a time-logarithmic recovery that may still be ongoing for the 2017 event at several sites or that may remain incomplete. The slope of the linear trend in seismic velocity is correlated with the downward vertical displacement of the ground measured by interferometric synthetic aperture radar, suggesting a causative relationship and supporting earlier studies on changes in the resonance frequency of sites in the Mexico City basin due to groundwater extraction. Our findings show how sensitively shallow seismic velocity and, in consequence, site effects react to environmental, tectonic and anthropogenic processes. They also demonstrate that urban strong-motion stations provide useful data for coda wave monitoring given sufficiently high-amplitude urban seismic noise.

Estimation of Inactivation time for the SARS-CoV-2 virus from the UV biometer in South Korea.

The coronavirus disease 2019 (COVID-19) is a result of the infection by "severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and has caused various social and economic effects over the globe. As the SARS-CoV-2 is effectively inactivated by the exposure to the UV-B radiation (shorter than 315 nm), the exposure time for inactivation of the SARS-CoV-2 was estimated using the broadband UV observation instrument over 11 observation sites in South Korea. For the limitation of the UV biometer, which has limited spectral information, the coefficient for conversion from the erythemal UV (EUV) to the radiation for virus inactivation was adopted before estimating the inactivation time. The inactivation time of SARS-CoV-2 is significantly dependent on seasonal and diurnal variations due to the temporal variations of surface incident UV irradiance. The inactivation times in summer and winter were around 10 and 50 min, respectively. The inactivation time was unidentified during winter afternoons due to the weak spectral UV solar radiation in winter. As the estimation of inactivation time using broadband observation includes the uncertainty due to the conversion coefficient and the error due to the solar irradiance, the sensitivity analysis of the inactivation time estimation was also conducted by changing the UV irradiance.

Co-designing with engineers for community engagement in rural Uganda

Co-design is seen as crucial for designing solutions for resource-constrained people living in developing countries. To best understand their needs, user engagement and co-design strategies need to first be developed. In this Design Practice Brief, a process of co-design was created and used to understand ways telecommunication engineers could engage with rural communities in Uganda. It reports and reflects on (i) the experience of co-designing with nondesigners and (ii) creating a co-design structure and developing co-design methods of engaging with community members living in developing countries. In doing so, it offers a format and case study for future practitioners facilitating and conducting co-design with nondesigners and contributes to a knowledge gap in the reporting and reflection of co-design practice. This case study is unique as the co-design practice was achieved remotely (online), crossed disciplines (designers and telecommunication engineers) and cultural boundaries (European and African). It finds that in co-designing with nondesigners, preparation and structure are key, with acknowledgement and management of cultural and discipline differences.

Disparities in spatial accessibility of primary care in Louisiana: From physical to virtual accessibility.

Telehealth has been widely employed and has transformed how healthcare is delivered in the United States as a result of COVID-19 pandemic. While telehealth is utilized and encouraged to reduce the cost and travel burden for access to healthcare, there are debates on whether telehealth can promote equity in healthcare services by narrowing the gap among diverse groups. Using the Two-Step Floating Catchment Area (2SFCA) and Two-Step Virtual Catchment Area (2SVCA) methods, this study compares the disparities of physical and virtual access to primary care physicians (PCPs) in Louisiana. Both physical and virtual access to PCPs exhibit similar spatial patterns with higher scores concentrated in urban areas, followed by low-density and rural areas. However, the two accessibility measures diverge where broadband availability and affordability come to play an important role. Residents in rural areas experience additive disadvantage of even more limited telehealth accessibility than physical accessibility due to lack of broadband service provision. Areas with greater Black population proportions tend to have better physical accessibility, but such an advantage is eradicated for telehealth accessibility because of lower broadband subscription rates in these neighborhoods. Both physical and virtual accessibility scores decline in neighborhoods with higher Area Deprivation Index (ADI) values, and the disparity is further widened for in virtual accessibility compared to than physical accessibility. The study also examines how factors such as urbanicity, Black population proportion, and ADI interact in their effects on disparities of the two accessibility measures.

Analysis of Compounding and Broadband Extinction Properties of Novel Bioaerosols

Artificially prepared microbial spores have excellent electromagnetic attenuation properties due to their special composition and structure. At present, studies on the optical properties of microbial spores have mainly focused on those with a single band or a single germplasm, which has limitations and cannot reveal the optical properties comprehensively. In this paper, 3 kinds of laboratory-prepared microbial spores were selected for compounding, and the spectral reflectivities of single-germplasm biospores and compound biospores were measured in the wavebands of 0.25–2.4 and 3–15 μm. The complex refractive indices (CRIs) were calculated in combination with the Kramers–Kronig (K-K) algorithm. Relying on the smoke box broadband test system, the transmittance of single-germplasm bioaerosols and compound bioaerosols from the ultraviolet (UV) band to the far-infrared (FIR) band was measured, and the mass extinction coefficients were calculated. The results indicate that the trend of the complex refractive indices of the compound spores is consistent with that of the single-germplasm spores with a larger particle size. For the single-germplasm bioaerosols, the lowest transmittance values were 2.21, 5.70 and 6.27% in the visible (VIS), near-infrared (NIR) and middle-infrared (FIR) bands, and the mass extinction coefficients reached 1.15, 0.87 and 0.84 m2/g, respectively. When AO and BB spores were compounded at 4:1, the extinction performance of the bioaerosols somewhat improved in all wavebands. These results can help to comprehensively analyze the optical properties of bioaerosols and provide ideas for the development of new extinction materials.

The Multi-Technology Footprint of the National Broadband Network in Australia: Exploring the Urban-Regional Divide and Socio-spatial Patterns for Inequality

The recent global pandemic renewed the importance of telecommunication infrastructure, as many COVID responses (e.g., working from home, home-schooling, e-commerce) were challenged by the inequity of access to broadband services and its underlying network. This paper examines the geospatial footprint of the National Broadband Network (NBN) in relation to the demographics of Australia's cities and regions. Through data made available by the NBN, which describes the technologies used in its multi-technology mix platform, and published demographic data available via the Australian Bureau of Statistics (ABS), we explore the equity of access to broadband technologies across the nation. The results show a persistent urban-regional divide in the NBN. The paper also offers a brief assessment of the complex and contradictory ways policy responses attempt to mitigate the digital divide, including updates to the national infrastructure project plans.

Mobile Broadband Adoption, Performance Measurements and Methodology: A Review

Mobile broadband (MBB) penetration has deepened globally over the last twenty years. This is largely due to the adoption of smart devices, improved mobile communications network coverage, and the perpetual drive to develop ever faster mobile and wireless communication technologies. However, information on the quality of service (QoS) delivered by MBB operators to the end users remains an issue of concern. This has driven independent researchers and mobile communication industry regulators to develop methodologies for independent and unbiased evaluation of the QoS offered by MBB networks. This paper provides a detailed review of MBB adoption and penetration across several regions of the world. It also includes the existing methodologies for evaluating the performance of MBB systems as experienced by the end user. Specifically, methodologies such as the drive and walk tests, crowd-sourced mobile device-based methods and the software applications they employ, and the dedicated measurement testbeds are reviewed. Based on this, the challenges of adopting each of the methods are discussed in order to make a case for the development of more robust, partially autonomous and scalable MBB measurement platforms for the future.

A Pandemic Snapshot: Libraries' Digital Shifts and Disparities to Overcome

In the fall and winter of 2020, New America embarked on a snapshot study to gather data on how – or if – people were discovering, accessing, and using their public libraries during the COVID-19 pandemic, with a focus on materials that libraries made available online. A full report on our findings, titled Public Libraries and the Pandemic: Digital Shifts and Disparities to Overcome, was published in March 2021. This article draws heavily from that report and also includes a policy update related to passage of the Infrastructure Investment and Jobs Act in the Fall of 2021. Analyzing data from a national survey in Fall 2020 of 2,620 people, we found mixed awareness of the public library's online resources, a shift toward online resources, mostly positive attitudes toward the public library and its online resources, and disparities in access to and use of the public library's online resources. This article also describes one library's creation of a digital navigator program to support digital literacy as an example of how to overcome some of these disparities. We conclude with specific recommendations for improving inclusivity, helping community members gain affordable internet access at home so they can use their library's online materials, and building awareness of library offerings via local organizations and schools. The aim is to leverage the lessons of the pandemic to help libraries launch more equitable ecosystems of learning across communities, providing access to knowledge, resources, and training, online and off.

Smart Healthcare Applications over 5G Networks: A Systematic Review

Provisioning of health services such as care, monitoring, and remote surgery is being improved thanks to fifth-generation cellular technology (5G). As 5G expands globally, more smart healthcare applications have been developed due to its extensive eMBB (Enhanced Mobile Broadband) and URLLC (Ultra-Reliable Low Latency Communications) features that can be used to generate healthcare systems that allow minimizing the face-to-face assistance of patients at hospital centers. This powerful network provides high transmission speeds, ultra-low latency, and a network capacity greater than that of 4G. Fifth-generation cellular technology is expected to be a means to provide excellent quality of medical care, through its technological provision to the use of IoMT (Internet of Medical Things) devices. Due to the numerous contributions in research on this topic, it is necessary to develop a review that provides an orderly perspective on research trends and niches for researchers to use as a starting point for their work. In this context, this article presents a systematic review based on PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses), with article selection based on inclusion and exclusion criteria that avoid bias. This research was based on research questions that were answered from the included works. These questions focus on technical characteristics, health benefits, and security protocols necessary for the development of smart healthcare applications. We have identified that a high percentage of existing works in the literature are proposals (56.81%, n = 25) and theoretical studies (22.73%, n = 10);few implementations (15.91%, n = 7) and prototypes (4.55%, n = 2) exist, due to the limited global deployment of 5G. However, the panorama looks promising based on proposals and future work that these technological systems allow, all based on improving healthcare for people.

Changes in mobile broadband infrastructure in georgia during the covid-19 pandemic

The COVID-19 pandemic brought the digital divide to center stage. This article investigates whether the crisis disrupted mobile broadband infrastructure, taking Georgia as a case study. We hypothesize that the pandemic could have slowed down ongoing infrastructure provision initiatives, as in other segments of the economy, or spurred them by bringing renewed attention and resources to overcoming the digital divide. We find that the per capita antenna gap between rural and micropolitan areas as compared to metropolitan has drastically reduced during the pandemic. Long-Term Evolution expansion was positively associated with the presence of vulnerable populations with variation across areas. © 2022 Penn State University Press. All rights reserved.

Home broadband and student engagement during COVID-19 emergency remote teaching

During the academic year 2019-2020, school buildings worldwide closed in response to the COVID-19 pandemic, necessitating a rapid shift to distance education. This study assessed the influence of high-speed broadband availability on student engagement with distance learning during this period in Ireland. Employing data from a representative sample of 206 secondary schools, student engagement as perceived by school principals was estimated to have been more adversely affected among schools located in areas with lower coverage of high-speed broadband. This may be partly explained by a lower probability of poorer student engagement among schools that deployed live online video teaching. While the costs and benefits must be considered, these findings may support the case for government intervention to provide greater equity in access to high-speed broadband. Where distance learning is required in future, secondary teachers should be supported in the use of live online teaching to better foster student engagement.

shifting perspectives: how covid-19 and in-home information and communication technology impacted u.s. residential internet perceptions

This study analyzes how the COVID-19 pandemic has altered individual perceptions of Internet service providers (ISPs) and Internet importance, reliability, and status as an essential public utility (EPU). The authors found that lower income, younger, women, and racial-ethnic minority participants had lower ISP and Internet reliability perceptions. The pandemic increased perception of Internet as an EPU by 15% and access to in-home Information and Communication technology was significantly related to perceptions of Internet importance and reliability. Significantly, women perceived higher importance of household Internet than men, specifically for education, employment, and telehealth. Additionally, racial-ethnic minorities relied on Internet for entertainment and education more than white participants. The authors provide recommendations for public utility models of Internet, Internet-reliant technology adoption campaigns, and policy that targets sociodemographic/geographic barriers to Internet access. © 2022 Penn State University Press.

Digital Disparities in Patient Adoption of Telemedicine: A Qualitative Analysis of the Patient Experience

Telemedicine's growth during the COVID-19 pandemic exposed digital and health disparities in U.S. communities. Public health advocates suggest disparities in healthcare access may be mitigated through free or low-cost broadband. However, prior research shows that many factors influence patient adoption of information technologies;therefore, increasing access to broadband alone is insufficient. This paper advances a patient-centered model of telemedicine (TM) adoption supported by qualitative interview data. The model illustrates that patient adoption of TM is driven by a complex sociotechnical system comprised of technology factors, structural factors underlying the provider's provision of TM, and individual patient factors. Findings highlight the importance of the physical place of the TM visit, the need for experienced TM healthcare workers and technology support for patients, the impact of provider-mandated technology on task-technology fit (TTF), and the strength of the patient-provider relationship. These factors affect patient perceptions of TTF and ultimately TM adoption.

Advanced Modelling of the Interplay between Public Governance and Digital Transformation: New Empirical Evidence from Structural Equation Modelling and Gaussian and Mixed-Markov Graphical Models

The research conducted in this paper aims to appraise the interlinkages between public governance and digital transformation at the level of the European Union. We employ two advanced approaches to modelling longitudinal data compiled at the level of the EU-27 Member States during the 2010–2021 period, namely, structural equation modelling and Gaussian and Mixed-Markov graphical models. The main results indicate positive impacts on government effectiveness arise from the human capital involved in complex activities that engage the use of digital services, e-government users, and integration of digital technologies, and the effect of demands and supplies of digital public services using open data. This further supports the government's capabilities in enforcing regulations and policies to control corruption and sustain the achievement of digital skills, at least at a basic level, by the entire society. Moreover, good perceptions and a higher degree of confidence in the rules of law have a positive influence on the need for connectivity of digital services, especially the supply side of fixed and mobile broadband. Lastly, a relevant impact of regulatory quality is identified in the digital connectivity of broadband infrastructure, which is enclosed by the public governance representative indicators under the influence of a stronger integration of digitalisation.
