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....

A lot of history on the beginning of the wired telephone system, Interesting but not sure how applicable. A few links were broken in the content, still able to get the content and able to do a search to find the info that was unavailable.

Overall very interesting and sets up the remainder of the course well. One thing and I may just not have looked enough to find it is advice on purchasing the Dragonboard 410c.

Lots of history is covered and difficult to remember the names. Some places connectivity is missing. AT$T downfall is not mentioned clearly. Last portion of this course, Applications of IoT is good and should have explained in detail. Happy to know about IoT which is one of my favorite subject to have learned. Thank you to Coursera and Ashok Leyland.

It was a good review of the technologies leading up to IOT. Some of the details of these technologies were not presented in the course, requiring internet research to complete quizzes. Also, some of the links provided for additional information were not accurate. Despite this shortcoming, it is a worthwhile introductory course to the IOT.

As someone who has designed Telecom systems and is familiar with things like Bellcore, this course provides a great overview and framework for how networks evolved.

The one issue I have is with the questions and answers in the quizzes and tests - many are difficult to understand. Some editing would easily clear this up.
