課程概述

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....

The issue with this course happens within the second week. The first quiz of the second covers material not discussed in the video lectures, not in the required reading, not in the optional reading, and there are no suggestions on how to/where to find this information. As I continued along with the course all the quizzes were the same way. A 4 question quiz should not take several hours of internet searching and several attempts over many days just to pass the quiz. I have my degree from a real university and any quiz was based on material we learned and had the materials to learn information. The beginning of this course is seriously lacking in information so as to provide the student with a reasonable opportunity to pass.

Professional courses are expected to be more technical and hands on. Few of the assessments were confusing.

Many of the week two quizzes and tests are based on information that is not in the lectures nor reading materials. I listen to the lectures and they have limited detail, and the quizzes are focused on very historical or detailed questions. I am spending the majority of my time in this week researching on line to try and find resources that i can learn from. This is not how i would like to take a course - my hope is to learn from lectures and be given reading assignments that i can study and learn from. I am hesitant to drop the class because i have invested so much time on it and wanted to get the certificate of completion - but the amount of time i am investing is not worth the payout. The teacher is very earnest and i believe he knows his subject matter well.

Really useless one.. All goes to history. Very tricky really useless questions that plays around the words "early", "original" etc. etc. Stay away from this part. You will spend a day looking for answers to questions such as whether Mr X was a president of the company from 1980-1990 or 1981-1990!!!

This course is very boring. The quiz has nothing to do with the contents of the video or reading materials. The information provided did not help me understand the topic. It is not worth time taking this class.

This is a good course to get up to speed with what has happened, we were there for some of it, but did not know the inside story.

A great historical overview of technological development that led up to the establishment of Internet of Things. Some concepts are flown over too fast, so if you don't have prior familiarity with them, they may be difficult to fully grasp, but educating students on every single concept that led to the IoT in depth is not the intention of the course anyways, and would take a lot longer than 2 weeks. I recommend noting down all interesting technical discoveries, principles, concepts etc. mentioned and doing some further exploration and study for one's own satisfaction, but as an overview of all tech development, and an overview of what IoT is and its applications, this course did a great job in my opinion!
