Preface
The phrase “Internet of Things” (IoT) alludes to the billions of physical devices connected to the Internet in order to exchange raw data and analyze the information. By collecting data from these devices and analyzing them, IoT makes the devices smarter, and the processes more efficient. IoT can bring endless opportunities to every aspect of our lives. For example, in a city environment, insights gained from that collected data can be used to manage resources and services more efficiently, leading to creating the concept of smart city. The city is smart, if it is connected. In a connected city, the traffic and transportation systems are managed more efficiently, the quality of urban services are improved, the performance of processes are enhanced, the consumption of resources are optimized, and the cost of services are reduced.
IoT is in early stages of its life. However, it is growing in a fast pace. As more and more IoT devices are deployed, we witness that every aspect of our lives is changed by the IoT.
This book sets out to introduce the IoT use cases and technologies. To demonstrate the effect of IoT and its potential to change our world, several practical examples are discussed. The book also discusses the existing wired and wireless communication technologies that have enabled IoT.
This book is organized in three chapters. The outline of this book is as follows: Chapter 1 introduces the fundamental concepts of IoT technology and explains IoT verticals, use cases and applications. Practical scenarios are discussed to demonstrate different applications of IoT in a variety of industries. Chapter 2 explains about wired IoT technologies as well as short range wireless communication technologies that have paved the way for IoT to be used for different applications in a variety of uses cases. Chapter 3 focuses on low power wide area technologies that provide long range connectivity for those applications where small amounts of data are transmitted often infrequently.
At the end of each chapter, there are several multiple choice and review questions which provide the readers with a better understanding of the topics that have been discussed in that chapter. The solution to those questions can be found at the end of the book.
