关于此课程： This course will provide an introduction and history of cellular communication systems that have changed our lives during the recent four decades and will become an essential and inseparable part of human life. The principles of wireless communication theory are covered with emphasis on the essential concept delivery to non-major learners in the easiest way. Then, it will be covered how such principles are realized and how multimedia services can be delivered in practical LTE cellular systems by which learners are connected and enjoys together in their lives. After completing this course, learners will be able to understand 1. What a cellular system is and how it has been developed so far 2. The very basic principles how information can be delivered efficiently using radio 3. How such principles are realized in LTE systems. 4. How people can be connected and multimedia services can be delivered in LTE systems
此课程适用人群： Learners who have general interest in information & communication technology (ICT)

This course is really good.Laernt many concepts of wireless/Its good for all of them who wants to understand concepts of cell in deep.
Doesn't go too much in depth. So it's very simple for a layman to understand, what exactly happens, that is, what is the flow of data between a user and the network in case of mobile communication
Great course. Tackles basics as well as advanced concepts in a way that is easy to understand.

A lot of interesting information but the difficulty of the various courses seemed very unbalanced to me. Some courses are quite basic, introductions to mobile networks but are followed by other courses that go quite deeply into the mathematical details of information theory while making many assumptions about the previous knowledge of the student.
Still a good course.
