Why take this course?

The Telecommunications sequence offers students enrolled in the Master of Information Technology program the opportunity to learn about modern telecommunication systems and techniques and to broaden their understanding of electronic communication systems within the information technology program. Because the typical MIT student does not have a first degree in engineering, there are no other courses open to students in the area of telecommunications. MIT students enrolled in Telecommunications learn the techniques and processes that enable digital data to be carried by optical fibers, satellites and wireless networks. This significantly improves their knowledge of information systems by providing a sound background in the physical layer of digital communication systems.

Learning Objectives

  • Select analog and digital modulations for the transmission of audio, video and data signals
  • Select appropriate error control strategies using forward error correction, error detection and automatic repeat request
  • Apply multiple access techniques to radio communication systems, including frequency, time, and code division multiple access
  • Describe the operation of local area networks, satellite communication systems, and the global positioning system
