Internet of Things: How did we get here?

University of California, San Diego via Coursera


It is hard to imagine life without your Smartphone – you have come to rely on it so much – for your work; to stay in touch with family and friends; to capture and share those special moments; to find your way around in a new neighborhood. Did you ever wonder how and when all this happened? Or how and when GPS sensors came to be in your cell phone?

In this course, we will explore the convergence of multiple disciplines leading to todays’ Smartphones. You will learn about the birth and evolution of Telephony Networks, Broadcast Networks (TV and Radio) and Consumer Electronics. We will discuss the impact of Internet, (multimedia) content, smartphones and apps on everyday lives. We will then look at how this emerging platform called the Internet of Things – wherein billions and trillions of devices communicating with each other and “the cloud” – could enable unprecedented, innovative products and services. Take this course if you want to understand what great new advances in mobile-enabled products will be coming our way!

Learning Goals: This course provides a core grounding in how science and technology have developed to enable the Internet of Things – in a way appropriate for any learner. For those interested in developing further hands-on expertise in designing and developing for the Internet of Things, this course will provide a context to the discoveries and converging technologies that will springboard the next round of innovations. After completing this course, you will be able to:

1. Compare how the telephone system works (that is, peer-to-peer networks) with how media delivery works (that is, broadcast/multicast networks).
2. Explain the tradeoffs between circuit switched networks (that is, dedicated resources) and packet switched networks (that is, shared resources).
3. Tell interesting stories about key innovations that transformed the communications, entertainment and consumer electronics industries.
4. Explain how email, YouTube, SMS, etc. work.
5. Find resources for those wishing to do more of a “deep-dive” into the above topics.

    Harry completed this course, spending 1 hours a week on it and found the course difficulty to be very easy.

    Avoid this course.

    The lecturer is extremely boring and the videos are just generally not very interesting, it's more a history lesson than teaching any skills. Very easy as well, no work required at all in order to pass the quizzes at the end of each week so I was able to complete the whole course in a couple of afternoons.

    Watch the first lecture... it never gets better. How could the instructors be happy enough with this product to publish it and then have the audacity to charge for it.

    Not OK: Technical problems with the site repeatedly moved me back to previously completed lessons. I quit when it moved me back to lesson 2 for the 3rd time. I expect technical perfection in paid courses.
    OK: Some of the lecture information was useful
    Less OK: Quiz questions were nitpicky
