14.1 Introduction

Internet of Things (IoT) refers to the interconnection and autonomous exchange of data between devices which are machines or parts of machines, also called sensors and controls. IoT can also be described as a network of physical objects that are connected to the Internet. The future connected world is expected to have tens of billions of IoT devices. This chapter focuses on the cellular IoT technologies. IoT enables a huge number of use cases in the areas of homes and consumers, industries, utilities and environment, logistics and connected cars. Example use cases are illustrated in Figure 14.1: smart metering for the collection of electricity or gas meter readings, smart grid for better utilization of power networks, traffic telematics for improved road efficiency and safety, industry applications for productivity improvements, smart homes for handy control of lighting and heating, health applications for collecting data from the body, environmental measurements, smart cities for higher efficiency and safety, object ...
