Objective

The objective of this course is to study broadband network architectures, focusing on the most recent developments in the evolution of communication and computer networks to the next generation and key enabling technologies. The first part of the course addresses the requirements, technology enablers and limitations in the design of broadband networks and the implementation of broadband applications and services. Wireline and optical broadband networks are analyzed in the second part of the course, with emphasis placed on transmission and baseband processing, multiple access and network architecture issues. In the third part, recent technological advances in the area of broadband wireless access are studied, including next generation WiFi and 5G communications. Finally, the most critical technology trends and system concept principles targeting ubiquitous broadband access in future networks are discussed, namely, Densification, Extreme Resource Sharing and Cloudification.
