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....

I think i can never get the introduction to telecommunication and web integrated together in such an awesome pedagogical manner. Thanks for providing this course.

Hay mucha información que requiere una cantidad enorme de tiempo para poder responder una pregunta demasiado extendida para que la respuesta sean menos de 4 letras.

La última parte del curso fue mucho mas interesante, debido a que la historia de la telefonía o el internet es algo que ya había visto.

Excellent title. Pretty much summarizes the entire course. Through out the entire course you will definately wonder why you are here. Your answer must be for IoT every time. If that's the case, then stay tune. If you manage to reach the end, you will also know how you got here.

This is a great course for people looking to know the history of IoT and as the name suggests how did we get here. the only thing wrong with this course is the assignment part as it is hilt disjoint and there are a lot of problems with the grading system.

The quiz questions were out of the topic. The course material and the quiz questions did not match. As a result it was very difficult to finish the course. Prior knowledge is very much required.

The present course does not talk about Amazon Cloud services or dragon boards.. Just the mention of it wont help. I am not sure if it is trimmed down version or anything.. but not happy..

Mainly disappointment in the quiz. Too many not mentioned in the lecture and takes too long to find the answer and in the end not finding the research rewarding

Most of the course is about history with fair technical information. there are topics which are discussed in less than 1 min , how can i be an expert in 1 min ?

The tests didn't match the content. Some of them even have wrong answers. Good content. But needs a Dragonboard to continue further the next courses

Too short.

The quizzes at the end of the each section barely relate to any of the video content and require you to google topics that were mostly not at all discussed in the course. The first week is about the history of the telephony industry which may be somewhat relevant for developing a cellular IoT solution, its just a very small piece of the rest of the Internet of Things ecosystem. Far too much content is dedicated to how telephones work when most of IoT solutions are not voice telephony applications and to the history of AT&T. The content feels like it was pulled from a course on the history of the telephony industry that was repurposed. Only saving grace of this course is that its only 2 weeks.

The quizzes given are not based on the learning resources provided within the course. Instead, you have to rely on researching on them yourselves or have prior knowledge in the field. There is also a lack of feedback for the quizzes, and when answers don't seem to tally with what you have found online, you are left scratching your head and questioning your own life's existence. In short, it was an extremely stressful and excruciating experience doing this course especially since this was not within my field of knowledge. Do not attempt this course if given the choice unless you have a background in this field or are extremely interested in this topic.

You should rename it to 90s style history of comunication from Bell to nowdays with useless facts about it.

I watched almost all first block but then I understood that I learnt nothing than I tried the IoT block, but it still wordy and superficial. Use more media to show your main ideas, take a class of public speaking and stop shaking a remote all the time you dont even use it.

I was incredibly excited to start this course. The outline looks amazing. For learning mediums like this, you have to start strong. Keep up the great work, you all look like you know what you're doing. You should certainly put some polish on all these videos. It's near impossible to follow along. I'd be curious in seeing the data on how many of your students finish this course.

Majority of the quizzes were poorly designed as the content tested was barely covered in the video lectures. We should not have to google the answers ourselves, that isn't the point of testing. The video lectures were also rather unsatisfactory as they glossed over many of the terms introduced instead of giving a more thorough explanation.

The notes and lectures given are barely related to the tests/quiz questions. From what I see from the forum, many people have problems doing the quiz questions as well. This has indeed made learning harder and less efficient for the students and hence I suggest that you make this course be more informative and useful.

Many of the things tested in the quizzes at the end cannot be reasonably extrapolated from the lectures and only occasionally from the readings. It was very difficult for me to attain this certificate and I am now disincentivized from trying the other coursera modules if they all follow in the same vein.

Arguably one of the worst online course that I've taken. Questions in the quiz weren't taught and little to no information were provided for learning in some later modules. For a beginner, it is extremely tedious to find the correct answers.

The Course material, with the exception of the last 2 modules, did not relate to the quiz question. Unless you are prepared to spend countless hours looking up the EXACT answer, most of the course is wasting your time.
