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.

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.

The answers are not in the content you provided!!!!

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!!!

Too much theory in the course and quizzes are very different from what is taught in the lectures.

It was good experience to learn from online. Coursera creating a platform for all to learn the coarse easy and joyful

It was great.

wonderful course, but weird quiz...

OK for the beginners as an introduction to IOT.

Course Videos and Quiz are hardly correlated.

I'm very satisfied with this course. I hope I can make my own IoT in my house.

very interesting subject and useful of latest technologies

First Part of the course is not relevant I guess. we struggled to complete the assignments. The last module of week 2 is good.

A lot of history knowledge has been included rather than materials that will be really helpful to proceed to further courses .

Thanks for complete insight of communication evolution.

Best way to learn new things

It is an interesting course to start with IoT

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.

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.

Good course, but I reckon the quiz should correspond to the lessons material.

definitivly an interesting course, which provides a good overview on communication technology. It presents very well the evolution of communication and networking. Interesting historical details are given. Quizzes might partly a bit tricky and require carefull study in the internet.

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

best thing i got..
