"Essentials of Short-Range Wireless" is an excellent summary of short-range wireless technologies, an area of rapidly growing importance within electronic engineering and product design.
The book manages to be both concise and extremely informative, and is written in a very easy-to-read style which is well-suited for professionals either with engineering degrees or with non-technical backgrounds.
The book provides the best summary of wireless architecture and parameters which I have seen, as well as a deeper analysis and comparison of the Bluetooth, IEEE 802.11/Wi-Fi, IEEE 802.15.4/Zigbee, and Bluetooth low energy wireless standards.
In addition, the book provides a great deal of practical information on implementing a wireless solution, as well as a description of the key product applications and emerging markets for short-range wireless technologies.
I would recommend this book to anyone with an interest in wireless product design. Nick Hunn has done the field a great service by writing a guide as compact, useful and descriptive as "Essentials of Short-Range Wireless".
