课程概述

Have you wondered how “Things” talk to each other and the cloud? Do you understand the alternatives for conveying latency-sensitive real time data versus reliable signaling data? Building on the skills from the Sensing and Actuation course, we will explore protocols to exchange information between processors. In this course, you will learn how VoIP systems like Skype work and implement your own app for voice calls and text messages. You will start by using the Session Initiation Protocol (SIP) for session management. Next, you will learn how voice codecs such as Adaptive Multi Rate (AMR) are used in 3G networks and use them for voice traffic in your app. Learning Goals: After completing this course, you will be able to: 1. Implement session initiation, management and termination on your DragonBoard™ 410c using SIP. 2. Discover other users and exchange device capabilities. 3. Compare and contrast narrowband and wideband codecs and experience the voice quality differences between them. 4. Implement and demonstrate VoIP calls using the DragonBoard 410c....

I liked the topic of communications, I am interested in carrying out developments in IoT and intellectually explore all the components that make up the internet of things.

Content was between shallow (everything but codecs) and deep (codecs), enthusiastic presenters but after a while the "you know" and "like" are getting really annoying.

OK. the main professor clearly knows his stuff. On the other hand he goes into unnecessary detail and then quizzes you on it even though its not relevant to the course (typical bricks and mortar education type BS). The assistant instructors (likely this guys students) are not as great and the whole thing is amateur night.

Big difference in difficulty between the math-heavy codec theory lectures and the other material which is quite basic. Not much to do with the DragonBoard.

Module about codecs was great.

The rest was too easy. An equivalent to reading manual on internet. No value added :(.

The Course is acceptable, however, it should be called, Introduction to VoIP communication or Developing VoIP applications rather than its current title.

Assignments are either super easy or never have a right answer

Personally, I will not recommend this course for other who want to understand IoT
