Delivery of broadband services to SubSaharan Africa via Nigerian communications satellite

Africa is the least wired continent in the world in terms of robust telecommunications infrastructure and systems to cater for its more than one billion people. African nations are mostly still in the early stages of Information Communications Technology (ICT) development as verified by the relatively low ICT Development Index (IDI) values of all countries in the African region. In developing nations, mobile broadband subscriptions and penetration between 2000-2009 was increasingly more popular than fixed broadband subscriptions. To achieve the goal of universal access, with rapid implementation of ICT infrastructure to complement the sparsely distributed terrestrial networks in the hinterlands and leveraging the adequate submarine cables along the African coastline, African nations and their stakeholders are promoting and implementing Communication Satellite systems, particularly in Nigeria, to help bridge the digital hiatus. This paper examines the effectiveness of communication satellites in delivering broadband-based services

Toward Universal Broadband in Rural Alaska

The TERRA-Southwest project is extending broadband service to 65 communities in the Bristol Bay, Bethel and Yukon-Kuskokwim regions. A stimulus project funded by a combination of grants and loans from the Rural Utilities Service (RUS), TERRA-Southwest has installed a middle-mile network using optical fiber and terrestrial microwave. Last-mile service will be through fixed wireless or interconnection with local telephone networks. The State of Alaska, through its designee Connect Alaska, also received federal stimulus funding from the National Telecommunications and Information Administration (NTIA) for tasks that include support for an Alaska Broadband Task Force “to both formalize a strategic broadband plan for the state of Alaska and coordinate broadband activities across relevant agencies and organizations.” Thus, a study of the impact of the TERRA project in southwest Alaska is both relevant and timely. This first phase provides baseline data on current access to and use of ICTs and Internet connectivity in rural Alaska, and some insights about perceived benefits and potential barriers to adoption of broadband. It is also intended to provide guidance to the State Broadband Task Force in determining how the extension of broadband throughout the state could contribute to education, social services, and economic activities that would enhance Alaska’s future. Results of the research could also be used proactively to develop strategies to encourage broadband adoption, and to identify applications and support needed by users with limited ICT skills.Connect Alaska.

Techno-economic viability of integrating satellite communication in 4G networks to bridge the broadband digital divide

Bridging the broadband digital divide between urban and rural areas in Europe is one of the main targets of the Digital Agenda for Europe. Though many technological options are proposed in literature, satellite communication has been identified as the only possible solution for the most rural areas, due to its global coverage. However, deploying an end-to-end satellite solution might, in some cases, not be cost-effective. The aim of this study is to give insights into the economic effectiveness of integrating satellite communications into 4G networks in order to connect the most rural areas (also referred to as white areas) in Europe. To this end, this paper proposes a converged solution that combines satellite communication as a backhaul network with 4G as a fronthaul network to bring enhanced broadband connectivity to European rural areas, along with a techno-economic model to analyse the economic viability of this integration. The model is based on a Total Cost of Ownership (TCO) model for 5 years, taking into account both capital and operational expenditures, and aims to calculate the TCO as well as the Average Cost Per User (ACPU) for the studied scenarios. We evaluate the suggested model by simulating a hypothetical use case for two scenarios. The first scenario is based on a radio access network connecting to the 4G core network via a satellite link. Results for this scenario show high operational costs. In order to reduce these costs, we propose a second scenario, consisting of caching the popular content on the edge to reduce the traffic carried over the satellite link. This scenario demonstrates a significant operational cost decrease (more than 60%), which also means a significant ACPU decrease. We evaluate the robustness of the results by simulating for a range of population densities, hereby also providing an indication of the economic viability of our proposed solution across a wider range of areas

Beyond Infrastructure: Broadband for Development in Remote and Indigenous Regions

Recent telecommunications stimulus projects in the U.S. and Canada were intended to increase availability of broadband through funding infrastructure investments, largely in rural and remote regions. However, true access involves more than availability; it also includes affordability and adoption. This paper presents a framework for analyzing broadband adoption that takes into consideration geographical, economic and cultural environments in indigenous communities. It includes an overview of potential social and economic impacts of broadband in remote areas, using examples from the Alaska study and the Canadian North. It then reports on results of an evaluation of Internet use and potential adoption of broadband in remote indigenous communities of southwest Alaska. Finally, the paper provides a comparative analysis of U.S. and Canadian policies intended to achieve affordable access to broadband for rural users and sustainable business models for rural broadband providers.Ye

Digital Diversity: Broadband and Indigenous Populations in Alaska

Presented at the Experts Workshop. Sponsored by the Ford Foundation.Alaska Natives comprise several cultural and linguistic groups including Inupiat, Yupik, Athabascan, Aleut, Tlingit and Haida, organized into some 226 tribes. Approximately two-thirds of the indigenous population live in more than 200 rural villages, most of which are remote settlements with fewer than 200 people and no road access. Since the late 1970’s, all communities with at least 25 permanent residents have had telephone service, but broadband connectivity remains limited. The major mechanism for extending Internet access to rural Alaska has been federal universal service funds, specifically the E-rate program that subsidizes Internet access for schools and libraries, and the Rural Health program that subsidizes connectivity for rural health clinics and hospitals. Under the federal Stimulus program, Alaska has also recently received funding for infrastructure to extend broadband in southwest Alaska, for improved connectivity for rural libraries, and for training and support for rural public computer centers. These initiatives primarily support improvements in Internet and broadband availability for rural Alaska. However, this paper proposes a more rigorous framework including not only availability, but more broadly access, and also adoption, and examines how these concepts apply to Alaska natives. The paper also examines other elements of digital diversity, including innovation in applications and content, ICT entrepreneurship, and participation in telecommunications policy-making

After Broadband: A Study of Organizational Use of Broadband in Southwest Alaska

The purpose of this research was to gain a preliminary understanding of how organizations including large and small businesses, Native corporations and organizations, and local and regional governments are using broadband that is now available in much of southwest Alaska. To learn about community access to broadband, interviews were also conducted with library and school staff in communities where broadband had been installed under the OWL (Online with Libraries) program. Further, the study identifies research from other sources that could help to predict what socio-economic impacts the availability and adoption of broadband may have in rural Alaska. Financial institutions use online connections for teller services and credit and debit card processing, and stated that more people in rural communities now have debit cards that they can use for online purchases and bill paying. Large retailers use online services for payroll, for pointof-sale (POS) transactions, and online ordering. Seafood processors rely heavily on connectivity with their head offices (generally in the lower 48) for administrative services including payroll, accounting, shipping and receiving, purchasing, and ERP (enterprise resource planning), and access data base software to track fish tickets. Seafood processors also provide Internet access for their employees, most of whom are seasonal and from other states or countries. Tourism businesses use broadband for online reservation systems and for guests, who increasingly demand connectivity even for remote vacations. Village corporations and tribal councils use online services to help their residents obtain hunting and fishing licenses and fishing permits, to learn about funding opportunities, and to file reports on grants. Local Governments connect online for interoffice communications and for payroll and other administrative functions. Other online applications and services include providing remote desktop access from other agency sites, use of online tools for land management and mapping, training including webinars for workforce development, and providing access to social services for clients. An economic development organization sends newsletters to communities electronically and packets of documents to its board members rather than relying on fax or courier. Websites are important for tourism-related businesses to advertise and promote their businesses and for nonprofits and local governments to provide information about their services. 5 Broadband now plays many roles in rural education. Most students are required to use the Internet for class assignments. High school students can connect to classes in advanced subjects in other communities, and may complete online courses for college credit. Libraries remain important locations for community access, with residents going online to connect with friends on Facebook, as well as to download content for e-books, file income tax, and apply for jobs and government benefits. School and library Wi-Fi provides access inside and near the buildings for residents with smartphones. Despite enthusiasm for broadband and the adoption of many broadband-based applications and services, most organizations interviewed identified problems with broadband, particularly with the pricing, stating that the terrestrial broadband network is too costly for them to take full advantage of online services and applications. While the scope of this study was too limited to estimate long-term benefits, it found that broadband is highly valued and increasingly important to businesses and nonprofit organizations and local governments in southwest Alaska. Broadband helps businesses to be more efficient in their operations and to extend their reach to new customers and suppliers. It also helps to improve the effectiveness of public sector services such as those provided by borough and city governments and extends access to education and training. Broadband is also likely to be an important component of strategies to develop ecotourism and other ecosystem services.Support for this research came from Connect Alaska with funding from the National Telecommunications and Information Administration (NTIA) for the work of the State of Alaska Broadband Task Force, with additional support from GCI.Executive Summary / Introduction / Research Methodology / Technologies and Technical Support / Broadband Applications / Education and Community Access / Health Care / Benefits of Broadband in Southwest Alaska / Problems and Limitations / Potential Long-Term Social and Economic Impacts / Conclusions and Recommendations / Referemce

Hybrid Satellite-Terrestrial Communication Networks for the Maritime Internet of Things: Key Technologies, Opportunities, and Challenges

With the rapid development of marine activities, there has been an increasing number of maritime mobile terminals, as well as a growing demand for high-speed and ultra-reliable maritime communications to keep them connected. Traditionally, the maritime Internet of Things (IoT) is enabled by maritime satellites. However, satellites are seriously restricted by their high latency and relatively low data rate. As an alternative, shore & island-based base stations (BSs) can be built to extend the coverage of terrestrial networks using fourth-generation (4G), fifth-generation (5G), and beyond 5G services. Unmanned aerial vehicles can also be exploited to serve as aerial maritime BSs. Despite of all these approaches, there are still open issues for an efficient maritime communication network (MCN). For example, due to the complicated electromagnetic propagation environment, the limited geometrically available BS sites, and rigorous service demands from mission-critical applications, conventional communication and networking theories and methods should be tailored for maritime scenarios. Towards this end, we provide a survey on the demand for maritime communications, the state-of-the-art MCNs, and key technologies for enhancing transmission efficiency, extending network coverage, and provisioning maritime-specific services. Future challenges in developing an environment-aware, service-driven, and integrated satellite-air-ground MCN to be smart enough to utilize external auxiliary information, e.g., sea state and atmosphere conditions, are also discussed

Electric Telegraph to e-Scotland: Networking remote and rural communities

There are said to be parallels in the impact that the advent of the telegraph and the internet had on their respective societies. This chapter looks at two examples of state intervention and subsidy in the development of those two communications infrastructures in remote and rural areas of Scotland, at either end of the revolution in electric communications. Both applied the technology of the day to break down geographical barriers, to increase connectivity, to spread information, and to enhance social and business links. Both initiatives grew in part out of a government concern that Scotland should not fall behind the level of technological provision available in other European countries, thereby disadvantaging Scottish business as well as citizens (a comparison with the state-owned telegraph systems in Belgium, Switzerland and France informed the 1868 Telegraph Act, and the development of a broadband infrastructure across a range of European Union countries has been quoted by the Scottish Government). The emphasis in both cases was on affordable wide-ranging availability to benefit individuals as much as business, though with an understanding that business needs would be the driver and would provide the bulk of the finance to establish and maintain the infrastructure. The first was a product of nationalisation with the expansion of the telegraph network from 1870 to 1872 driven by demand. Following is an analysis of that demand and its impact, alongside a description of the development of the network across remote and rural areas over the two years of the scheme. The second examines the rationales behind Scottish Government initiatives since 2001 to extend broadband provision and outlines the technical solutions devised in partnership with commercial operators and funding bodies to reach non-commercially viable areas and to stimulate take up
