Provides a detailed analysis of the technologies chosen for and driven by applications of the Internet of Things

Wireless Technologies for the Internet of Things: A Layered Approach presents a holistic perspective toward Internet of Things (IoT) from applications to interfaces for home automation, sensor networks, smart grid, and healthcare. The author a noted expert in the field examines IoT as a protocol–stack, and details the physical layer of the wireless links, the networks created by the various nodes, and the applications which drive the need for IoT. The text outlines the standards for ZigBee, Bluetooth LE, Z–Wave, Wi–Fi, and Thread and covers the physical layers as a protocol stack including common theory, modulation schemes, access methods, bands, and Bluetooth.

The author includes a discussion of authentication and encryption and offers an analysis of the network layer. He introduces mesh networks, controllers and end devices, and covers a variety of topics in the medical industry. The book also presents standards, service models, and communication models for a variety of personal healthcare devices including blood pressure monitors, pulse oximeters, glucose meters, thermometers, weighing scales, independent living activity hubs, and sleep apnea breathing therapy equipment. This important text:

• Introduces ITU–T G.9959 as a physical layer technology standard enabling IoT
• Takes a layered approach in order to cultivate an appreciation for the various standards that enable interoperability
• Explores a number of application areas such as: home automation, industrial control, smart grid, distributed networks, and more
• Presents IEEE 11073, 1547, 2030 and Open ADR as applications of IoT

Written for IoT application and platform developers as well as engineers involved in DSP, network implementation, and wireless communications, Wireless Technologies for the Internet of Things: A Layered Approach offers an inclusive overview of the complex field of IoT, exploring its beneficial applications that are proliferating in a variety of industries.
