ABSTRACT
Mobile Communications are exponentially evolving to allow any electronic device wirelessly to connect to the Internet. The first decade of the 20th century saw how the computer and the phone have converged into a single concept of user terminal, making mobile telephony and nomadic computing facilities coexist in a single device: the smartphone. The deployment of new radio networks is based on facilitating access to devices by installing small cells or access nodes, which are interconnected in groups by high-speed backhaul networks, and cooperate within the group to manage the resources in a joint cooperative area. Spectrum availability is always crucial for the evolution of Radio Communications. Radio propagation for wireless networks has been extensively investigated for over 20 years, mainly towards networks planning for 2G, 3G, and 4G mobile communications. The chapter also presents an overview on the key concepts discussed in this book.
