Abstract

Satellites are well suited for broadband communications. In this paper we consider the special features of satellite systems, some of the broadband applications that are well-suited for satellites and some of the technologies which make possible broadband satellite communications, as well as the research programs that led to their development. We describe how such technologies, and other factors, have contributed to the evolution of broadband satellite systems, and discuss some of the challenges in establishing such systems. We finish by offering some concluding remarks on the role of satellites for broadband access.
