Mastering IOT

By: Colin Dow, Perry Lea

Overview of this book

The Internet of Things (IoT) is the fastest growing technology market. Industries are embracing IoT technologies to improve operational expenses, product life, and people's well-being. We’ll begin our journey with an introduction to Raspberry Pi and quickly jump right into Python programming. We’ll learn all concepts through multiple projects, and then reinforce our learnings by creating an IoT robot car. We’ll examine modern sensor systems and focus on what their power and functionality can bring to our system. We’ll also gain insight into cloud and fog architectures, including the OpenFog standards. The Learning Path will conclude by discussing three forms of prevalent attacks and ways to improve the security of our IoT infrastructure. By the end of this Learning Path, we will have traversed the entire spectrum of technologies needed to build a successful IoT system, and will have the confidence to build, secure, and monitor our IoT infrastructure. This Learning Path includes content from the following Packt products: Internet of Things Programming Projects by Colin Dow Internet of Things for Architects by Perry Lea

The radio spectrum


Wireless communication is based on radio waves and bands of frequencies within the overall radio spectrum. We will cover long-range communication in the next chapter for cellular and other long-range mediums, here we focus on the 1000 meter range or less. Here, we will look at the spectrum allocation process as well as the typical frequency uses for WAN devices.

Governing structure

The spectrum ranges from 3 Hz to 3 THz, and allocation within the spectrum is governed by the International Telecommunication Union (ITU). A band is considered a portion of the spectrum that can be allocated, licensed, sold, or freely used depending on the frequency. From an ITU perspective, the bands are categorized as follows:

Within the United States, the Federal Communications Commission (FCC) and the National Telecommunications and Information Administration (NTIA) control the frequency spectrum usage rights. The FCC administrates the non-Federal spectrum usage, while the NTIA administers...
