This book presents an investigative approach to globalization-driving technologies that efficiently deliver ubiquitous, last-mile, broadband internet access to emerging markets and rural areas. Research has shown that ubiquitous internet access boosts socio-economic growth through innovations in science and technology, and has a positive effect on the lives of individuals. Last-mile internet access in developing countries is not only intended to provide areas with stable, efficient, and cost-effective broadband capabilities, but also to encourage the use of connectivity for human capacity development. The book offers an overview of the principles of various technologies, such as light fidelity and millimeter-wave backhaul, as last-mile internet solutions and describes these potential solutions from a signal propagation perspective. It also provides readers with the notional context needed to understand their operation, benefits, and limitations, and enables them to investigate feasible and tailored solutions to ensure sustainable infrastructures that are expandable and maintainable.
