課程概述

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....

Was a good course. Videos lectures could be better prepared. The Codecs were a bit complex and needed extra reference material

There's a lot of useful information in this course, but it's communicated in a very clear way. I suggest the teachers focus on improving the audio codecs material . This are hard concepts to graps and I feel the institute should invest in animation or multimedia production to clarify this. It's all very informative though I feel I was not able to put to practice nor to fully understand the models. A list of references to videos or some other sources would have been very useful.

For the better part, the section about setting up linphone and using Android Studio to program a little VoIP app is very clear and exciting.
