This book presents the fundamentals of wireless communications and services, explaining in detail what RF spectrum management is, why it is important, which are the authorities regulating the use of spectrum, and how is it managed and enforced at the international, regional and national levels. The book offers insights to the engineering, regulatory, economic, legal, management policy-making aspects involved. Real-world case studies are presented to depict the various approaches in different countries, and valuable lessons are drawn. The topics are addressed by engineers, advocates and economists employed by national and international spectrum regulators. The book is a tool that will allow the international regional and national regulators to better manage the RF spectrum, and will help operators and suppliers of wireless communications to better understand their regulators.

Over the past 20 years UWB has been used for radar, sensing, military communications and niche applications. However, since the FCC ruling in 2002, which allowed the commercial operation of UWB for data communications, UWB has changed dramatically. Implementation oriented, this volume explores the fundamentals of UWB technology with particular emphasis on impulse radio (IR) techniques. It explains the key physical layer aspects of UWB technology, especially in communications and in control applications, and examines the multiple access (MAC) issues which are emerging as a hot area for practical UWB systems. Offers practical information about implementation Addresses issues of modulation possibilities, appropriate circuits for UWB, an example circuit design, MAC protocol issues and use of UWB for positioning applications Includes a literature survey examining books, articles and conference papers presenting the basic features of UWB technology and current systems Features a patent database search providing a historical perspective to the state-of-the-art technology UWB Theory and Applications will be indispensable to researchers interested in the practical issues of UWB technology and realistic assumptions of UWB, as well as engineers interested in implementing UWB devices.

This book deals with practical concepts of Electromagnetic Compatibility testing and design. Given the scorching pace at which electronic gadgets are evolving, deadlines associated with product design are shrinking rapidly. In such a scenario, the designer obviously has no time to read mathematical theory. Keeping this fact in mind, the book explains only the practical aspects of EMC design without resorting to equations or mathematical derivations whatsoever. It has been designed in such a way that the designer can immediately incorporate EMC measures without worrying about the mathematics behind it. The book starts with EMC fundamentals, speaks about EMC standards and then goes on to explain various EMC test methodologies in detail. In the subsequent chapters, various design measures like filtering, shielding, grounding & bonding, PCB design and cable routing are discussed thoroughly. These measures will enable manufacturers to design a compliant product at the design stage itself thereby saving time and money that would otherwise be required for costly retrofits once the design is frozen.

This"know-how"book gives readers a concise understanding of the fundamentals of EMC, from basic mathematical and physical concepts through present, computer-age methods used in analysis, design, and tests. With contributions from leading experts in their fields, the text provides a comprehensive overview. Fortified with information on how to solve potential electromagnetic interference (EMI) problems that may arise in electronic design, practitioners will be betterable to grasp the latest techniques, trends, and applications of this increasingly important engineering discipline. Handbook of Electromagnetic Compatibility contains extensive treatment of EMC applications to radio and wireless communications, fiber optics communications, and plasma effects. Coverage of EMC-related issues includes lightning, electromagnetic pulse, biological effects, and electrostatic discharge. Practical examples are used to illustrate the material, and all information is presented in an accessible and organized format. The text is intended primarily for those practicing engineers who need agood foundation in EMC, but it will also interest faculty and students, since a good portion of the material covered can find use in the classroom or as a springboard for further research. The chapters are written by experts in the field Details the fundamental principles, then moves to more advanced topics Covers computational electromagnetics applied to EMC problems Presents an extensive treatment of EMC applications to: Radio and wireless communications, Fiber optic communications, Plasma effects, Wired circuits, Microchips, Includes practical examples, Fiber optic, Communications, Plasma effects, Wired circuits, Microchips, Includes practical examples
