6G Visions for a Sustainable and People-centric Future

6G is currently under definition, being often addressed from a plain telecommunications perspective as an evolutionary paradigm that represents an extension of 5G. Having as a horizon 2030, 6G initiatives are being deployed across the globe to further ignite the development of 6G services. At its philosophical core, 6G embodies the "human in the loop" principle. The research effort being developed towards 6G requires an interdisciplinary approach that ignites discussion across different key technological sectors, ranging from communications up to services and business cases. The contributions of this book to research in the field concern an evolutionary and interdisciplinary design of 6G as a paradigm that can be addressed by working together four different computational areas: communications; satellites and navigation; sensing; services. The book is derived from initial brainstorming that was developed during the 11th CONASENSE Symposium held in October 2021 in fortiss, Munich, Germany. Several international experts contribute to an overview of 6G key challenges, new networking trends and challenges to be overcome, and advanced 6G services. The book starts with a perspective on 6G challenges and use-cases beyond the 2030 horizon, to then continue to address the role of non-terrestrial networks and cognitive, service-centric satellite networks in future 6G services. Still with focus on 6G adaptive networking, the book continues with a debate on the need to integrate social awareness based on an interdisciplinary approach in network operations. Then, specific examples of advanced services (quantum imaging and holography; localization of the Internet of remote things) are discussed. The book is, therefore, intended to assist in developing critical thinking to back up novel networking, applications, and services towards 6G.
