Course Description

This is an introductory course in mobile and wireless networks. The course is open to graduate and undergraduate (especially seniors) students. The course covers fundamental techniques in design and operation of the second, third, and fourth generations of wireless cellular networks and wireless LANs. The emphasis is on the traditional design of cellular mobile systems, including both voice and data services. We will start by covering topics related to the wireless channel; i.e., the radio propagation models and the multiple access techniques. Then, we will proceed with studying the engineering of a cellular system, including detailed explanation of some standards of the existing common air interfaces for voice and data (e.g., GSM, GPRS, IS-95, WCDMA, LTE, WiFi, WiMAX). We will learn how signaling is performed in cellular networks, how a mobile session and a mobile call are controlled, and how security features are designed in those networks. Introduction to third generation wideband systems and novel technologies, such as Bluetooth and ad hoc networks, will be covered too.

The course is a mixture of theoretical, engineering, and practical topics in contemporary wireless systems.

*  Number of Credits: 4

*  Prerequisites: ECE 3100 or equivalent (essential, absolutely no exceptions)
