Course description

This course provides a basic review of modern telecommunications technologies, and how they developed from the legacy systems used by telephone carriers in the developed world.

The central theme of the course is the remarkable extent to which, in a few short years, most telecommunications services have been subsumed by the Internet and Internet-related technologies. We pay particular attention to the adoption of Internet protocol (IP) and packet-switched networking, which has replaced conventional voice-telephone technology and circuit-switching. In parallel with these advances in network design, telecommunications has undergone a transformation in backend technologies. One of the most far-reaching of these trends concerns the evolution of local telephone exchanges into data centers to support communications across the public Internet. We also examine how these changes are related to the revolution in ICTs known as cloud computing.

The course is designed to allow students to expand on what they have learned in 2000-level courses such as COMN 2500 (Information and Technology), and 3000-level courses such as COMN 3510 (Considerations in Telecommunications), while preparing them for more advanced work in 4000-level courses such as COMN 4520 (Electronic Information Network Marketplace).

Course outcomes

By taking this course, you can expect to:

  1. understand the limits of your knowledge as a “digital native”
  2. appreciate the advantages of learning without the distractions of phones and computers
  3. learn what sets telecommunications apart from broadcasting and other mass media
  4. learn how the Internet works as an engineering marvel
  5. conduct some basic measurements of network performance
  6. become more aware of the many risks to your online security
  7. develop numeracy skills like how to construct a clear, accurate data table
  8. become a more critical consumer of telecom services like Internet access.
