Presentation
This course serves as an introduction to the fundamentals of fixed, mobile and wireless networks. The first part is devoted to fixed telephony networks, with emphasis on the essential functions and features of the telephone network, and the related architectural issues. The second part of the course gives the basics of cellular networks principles and an overview of mobile telephony. The major part of the course is a project realized with a professor from the Networks, Security and Multimedia Department of RSM
Prerequisites
Students should take the course “Networking fundamentals” before this one.
Objectives
The goals of this course are:
• To explain the architecture and building blocks of a telephony network, like: voice coding, local loop, access and transport networks, switching, transmission, SS7 signaling.
• To present how to specify an elementary service (telephony service) following a quality-of-service-oriented approach (interactivity analysis).
• To introduce the basic concepts of cellular networks and offer a survey of the main mobile telephony systems.
Duration:
21h
