ECE 4614 Telecommunication Networks (3C)

Architecture, technology, operation, and application of telecommunication networks including digital telephony, data networks, and integrated services networks. Design and analysis of networks for voice, data, and video applications.

What is the reason for this course?

Computer networks are pervasive. Electrical and computer engineers must understand the architecture, technology and applications of such networks. In addition, they must understand how the existing telecommunications infrastructure is evolving to provide integrated voice, data, and video communications services that are critical to the operation and competitiveness of companies, government, and other organizations. The continued growth of the Internet has generated new applications and spurred the need for higher speed local access. Advances in telecommunications technology and applications has increased the demand for electrical and computer engineers possessing a systems-level understanding of present telecommunications networks and the forces shaping their future.

Technical Elective. Typically offered: Spring. Program Area: Communications.

Prerequisites: 2504, 2704, STAT 4714.

Why are these prerequisites or corequisites required?

To understand the signals that are carried in telecommunication networks and the protocols of computer networks, students must be familiar with the spectral representation of signals as covered in 2704, and basic computer architecture and logic circuit principles as covered in 2504. To understand traffic models and performance analysis of networks, students must be familiar with basic probability models as covered in STAT 4714, Probability and Statistics for Electrical Engineers.
