Connectivity Technologies for IoT
Sunil Cheruvu, Anil Kumar, Ned Smith, David Wheeler · Apress eBooks · 2019
Abstract Internet of Things (IoT) is a set of technologies that are enabling new use cases and delivering services across a wide variety of markets and applications. When people think of IoT, they often think of home or personal IoT. However, IoT will play a role in many commercial applications such as smart manufacturing, smart cities, autonomous cars, building automation, and healthcare. How will an IoT-enabled device communicate what it knows to the Internet? Suitable connectivity solutions range from a multitude of wired connectivity technologies such as Ethernet to wireless technologies like Wi-Fi and even 5G cellular. Many solutions need a combination of multiple communication technologies. For example, a smart car system playing video or using GPS navigation might need 4G LTE in order to communicate with the outside world and Wi-Fi and Bluetooth to communicate with devices like phones and rear seat entertainment (RSE) used by the passengers. In this chapter, we will take a look at a selected set of connectivity technologies that enable these applications.
