THz wireless communications: challenges and paradigm shift

Abstract

Information and Communication Technologies (ICT) have a significant impact in several aspects of modern society, facilitating the vision of ubiquitous communication and the internet of things. ICT has and will continue to have a substantial influence on the way we communicate, how information is disseminated, the way we work and conduct business, social life, and ultimately on the macroeconomic growth. All these factors, in turn, affect society enabling improvements in infrastructure and standard of living. The challenges of the growing need for bandwidth, and the evolution of several generations of communication systems – 3G to 5G – have been achieved as a result of the interplay between technologies based on optical systems (high speeds at a global level on the planet) and ubiquitous communication facilitated by wireless radio-frequency communication systems and more recently mobile communications between vehicles and via satellite.
