Course description

This course provides a basic review of modern telecommunications technologies (no smoke signals), and how they developed from the legacy systems used by telephone carriers for most of the last century.

The central theme of the course is the remarkable extent to which, in a few short years, conventional telecommunications services have been superseded by Internet-related functions and technologies. This trend is epitomized by the widespread adoption of the Internet protocol suite and packet-switched networking, in place of voice-telephone technology and circuit switching. Paralleling these advances in network design, telecommunications has also undergone a transformation in the backend technologies that power our personal messaging and social media platforms, such as data centers built around the cloud computing model.

The course will 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).
