Abstract

How do you imagine the future communication networks? Which are going to be their enabling new technologies: holographic arrays and quantum communications? Trying to answer these and related questions, researchers worldwide have begun to study new avenues, because the future networks are expected to be a wise combination of disruptive technologies and improved existing ones in 5G. Can you imagine a user centric network that you can activate whenever and wherever you are? A network with distributed intelligence and memory, that can transmit at terabits per second and to carry out fast computing over the air, in order to automate decisions and to enable a sustainable and always-best-connected network? You should not think only about big cities, but also about small villages, ad hoc communities, oceans, etc. Such a vision is only possible if terrestrial and satellite communications become just one. We are most familiar with terrestrial radio communications, but what about satellite communications? When and where are they used? How do they operate? This chapter digs into these questions and brings satellite communications (satcom) closer to the reader with a combination of tutorial description and new avenues for research. First, the chapter will explain the key role of satcom in the origins of digital communications, due to the peculiarities of the satellite channel. These peculiarities have challenged the integration of satellite and terrestrial communications. Next, new technological aspects that are currently fostering and enabling this integration are explained. To properly design the future wireless networks, it is key to understand the differences between the satellite and the terrestrial segments. This chapter reviews them and introduces a new communication paradigm, which allows terrestrial and satellite segments to better integrate into a 3D network and may create opportunities for new satellite leaded findings in 6G.
