Sensors and Low Power Signal Processing Review

Average Reviews:

(More customer reviews)A 117-page book is necessarily going to be an introduction to a subject and not a detailed treatment. The coverage of wireless technologies in 14 pages (Chapter 4)--from basic RF theory to an explanation of various waveforms--is necessarily superficial, but if you're not up to speed on RF technology it's as good an overview as you could hope for in the space provided. Still, the coverage of low-power circuit design in 10 pages (Chapter 3) is not going to help you design circuits, particularly given the focus on how semiconductor devices work the way they do, which is only of theoretical interest to your average circuit designer, who learned this stuff in school anyway. The authors' coverage of the various types of sensors, however, is particularly good, especially their coverage of emerging biophotonic, electrochemical and electromechanical sensors.
In short this is a quick introduction to low-power sensors and a wide range of applications in which they're found. It's well suited to an undergraduate engineering course, though if you're new to such networks and considering implementing one, this book is a good place to get started.

Low-power sensors and their applications in various fields ranging from military to civilian lives have made tremendous progress in the recent years. Low-power and extended battery life are the key focuses for long term, reliable and easy operation of these sensors. Sensors and Low Power Signal Processing provides a general overview of a sensor's working principle and a discussion of the emerging sensor technologies including chemical, electro-chemical and MEMS based sensors. Also included is a discussion on design challenges associated with low-power analog circuits and the schemes to overcome them. Finally, a short discussion of some of the simple wireless telemetry schemes best suited for low-power sensor applications and sensor packaging issues is discussed. Applications and sensor prototypes included are environmental monitoring, health care monitoring and issues related to the development of sensor prototypes and associated electronics to achieve high signal-to-noise ratio will also be presented.

Low-Rate Wireless Personal Area Networks: Enabling Wireless Sensors With IEEE 802.15.4 (Ieee Standards Wireless Networks) Review

Average Reviews:

(More customer reviews)Obviously the target audience is a technologist, and more specifically those interested in implementation. However, the first two chapters are good for Marketing audiences as well. The meat of the book was chapters 3-7. My favorites were 5 and 6. HIGHLY RECOMMENDED read if you are a designer pondering wireless communications for a product design, and you are considering 802.15.4 technology.

This SECOND EDITION of Low-Rate Wireless Personal Area Networks: Enabling Wireless Sensors with IEEE 802.15.4 is the newest handbook in the IEEE Standards Wireless Networks Series.This updated book now includes detailed information from the revised IEEE Std 802.15.4-2006, which includes the amendment IEEE 802.15.4b. IEEE Std 802.15.4 was developed to address low-cost and low-power design to enable applications in the fields of industrial, agricultural, vehicular, residential, and medical sensors and actuators. This book offers the reader an insider's view of the standard. Features include an overview of the standard, the motivation and vision behind it, background on the technology, technical features and components, application scenarios, and material not covered in the standard related to the network layer functionality for applications.The book also focuses on implementation and system design considerations, including an analysis of system-level, real-world issues that will be important for prospective implementers to consider.Presented in a concise and easy to read format by experts intimately involved in the development and writing of the standard, this guide is an invaluable resource to the standard for those interested in the field of "simple" wireless connectivity.Low-Rate Wireless Personal Area Networks, 2nd Edition, is a MUST READ for anyone who wants to fully understand the inner-workings and possibilities of the IEEE 802.15.4 standard.--This text refers to the Paperback edition.

ZigBee Wireless Networks and Transceivers Review

Average Reviews:

(More customer reviews)This book is excellent for learning ZigBee/IEEE802.15.4 and short-range wireless networking. I found this book very useful and it has answered many of my questions. I am impressed with its content and this book should be the definitive starting purchase for any ZigBee or IEEE 802.15.4 developer. I manage a small team of application engineers building proprietary wireless devices. We bought all three ZigBee books currently available on the market and we like this book the most.
Here are my comments regarding this book:
Pros:
1.Excellent introduction to ZigBee and IEEE 802.15.4. This book is well written and started us on the right track. The book goes beyond the basics.
2.This book contains a great introduction to the field of short-range wireless networking. Many of the materials discussed in this book (e.g., range calculations, battery life calculations, antenna selection, etc.) are useful and relevant, even if the short-range wireless networking standard is not ZigBee.
3.I liked the fact that the book comes with a website (http://www.LearnZigBee.com). We have used the calculators posted on the website to estimate battery life and various range extension calculations.
4. Coexistence is a challenge for us and this book answered most of my questions regarding coexistence of ZigBee with other proprietary wireless devices.Cons:
1. The last chapter is a review of other wireless networking standards (e.g., WirelessHART), but it does not go beyond the basics of these alternative standards. We wished to see more information about these standards.
