Course Summary:

The Global Telecommunications Network 31:10 minutes

Investigate the beauty and complexity of the public switched telephone network (PSTN). Optimized for transmission of the human voice, it comprises a vast array of conventional phone lines, fiber-optic cables, microwave links, and other media. Trace its evolution to the remarkable system in use today.

Cellular Phone Technology 29:37 minutes

Why is cell phone service sometimes so unpredictable? Get inside the cellular network to learn how clever engineering makes a surprisingly large number of two-way conversations possible over a very narrow broadcast spectrum. Also see how the system leads to dead spots, dropped calls, and other familiar cell phone hassles.

Learning Objective:

By the end of this course the student will understand the complexity of the public switched telephone network (PSTN) and recall its evolution to the remarkable system in use today. By the end of this course the student will also learn how clever engineering makes a surprisingly large number of two-way conversations possible over a very narrow broadcast spectrum.
