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.

物联网:我们如何到达这里?:很难想象没有智能手机的生活-您已经非常依赖它了-您的工作;与家人和朋友保持联系;捕捉并分享那些特殊时刻;在新的社区中找到自己的出路。您是否想知道所有这些事情是如何发生的以及何时发生的?或者GPS传感器如何以及何时出现在您的手机中? 在本课程中,我们将探索导致当今智能手机发展的多种学科的融合。您将了解电话网络,广播网络(电视和广播)和消费电子产品的诞生和发展。我们将讨论Internet,(多媒体)内容,智能手机和应用对日常生活的影响。然后,我们将研究这个称为物联网的新兴平台,其中数十亿和数十亿的设备相互之间以及“云”进行通信,该平台如何实现前所未有的创新产品和服务。如果您想了解支持移动产品的巨大新进展将成为我们的方式,请参加本课程! 学习目标:本课程为科学和技术如何发展以实现物联网提供了核心基础-以适合任何学习者的方式。对于有兴趣在物联网设计和开发方面进一步动手实践的专业人士,本课程将为发现和融合技术提供背景,这些技术将推动下一轮创新。完成本课程后,您将能够: 1.比较电话系统的工作方式(即对等网络)和媒体传递的工作方式(即广播/多播网络)。 2.解释电路交换网络(即专用资源)和分组交换网络(即共享资源)之间的权衡。 3.讲述有关改变通信,娱乐和消费电子行业的关键创新的有趣故事。 4.说明电子邮件,YouTube,短信等的工作方式。 5.为那些希望对上述主题进行更多“深入研究”的人找到资源。
