At the present time, the wireless communications research community and industry are about to start discussions on standardization activities for the fourth generation (4G) of these systems. In the meantime, the research community has generated a number of promising solutions for significant improvements in system performance. Adaptive coding and modulation, iterative (turbo) decoding algorithms, space–time coding, multiple antennas and MIMO channels, multicarrier modulation, multiuser detection and ultra wideband radio are examples of enabling technologies for 4G.

The focus of the book is on the system elements that provide adaptability and reconfigurability, and discussion of how much these features can improve the system performance. At the same time, the book provides a solid overview of the conventional technologies, although this is not the focus of our discussion. The measure of performance is the reconfiguration efficiency defined as a ratio between the reconfiguration (signal to noise ratio) gain and the relative increase in complexity.

The content of this book is based on the results of the research community in the field of wireless communications across the globe, and a number of authors have been explicitly cited in the text. This by no means represents an exhaustive list of those whose work isbuilding up the enabling technology for 4G.

Defend against the latest pervasive and devastating wireless attacks using the tactical security information contained in this comprehensive volume. Hacking Exposed Wireless reveals how hackers zero in on susceptible networks and peripherals, gain access, and execute debilitating attacks. Find out how to plug security holes in Wi-Fi/802.11 and Bluetooth systems and devices. You'll also learn how to launch wireless exploits from Metasploit, employ bulletproof authentication and encryption, and sidestep insecure wireless hotspots. The book includes vital details on new, previously unpublished attacks alongside real-world countermeasures.

This book aims to present modern wireless communication concepts in a coherent and unified manner and to illustrate the concepts in the broader context of the wireless systems on which they have been applied.

This book is written as a textbook for a first-year graduate course in wireless communication. The expected background is solid undergraduate/beginning graduate courses in signals and systems, probability and digital communication. This background is supplemented by the two appendices in the book. Appendix A summarizes some basic facts in vector detection and estimation in Gaussian noise which are used repeatedly throughout the book. Appendix B covers the underlying information theory behind the channel capacity results used in this book. Even though information theory has played a significant role in many of the recent developments in wireless communication, in the main text we only introduce capacity results in a heuristic manner and use them mainly to motivate communication concepts and techniques. No background in information theory is assumed. The appendix is intended for the reader who wants to have a more in-depth and unified understanding of the capacity results.

The more than 230 exercises form an integral part of the book. Working on at least some of them is essential in understanding the material. Most of them elaborate on concepts discussed in the main text. The exercises range from relatively straightforward derivations of results in the main text, to “back-of-envelope” calculations for actual wireless systems, to “get-your-hands-dirty” MATLAB types, and to reading exercises that point to current research literature. The small bibliographical notes at the end of each chapter provide pointers to literature that is very closely related to the material discussed in the book; we do not aim to exhaust the immense research literature related to the material covered here.

This first-of-its-kind book, from expert authors actively contributing to the evolution of Bluetooth specifications, provides an overview and detailed descriptions of all the security functions and features of this standard’s latest core release. After categorizing all the security issues involved in ad hoc networking, this hands-on volume shows you how to design a highly secure Bluetooth system and implement security enhancements. The book also helps you fully understand the main security risks involved with introducing Bluetooth-based communications in your organization.

This cutting-edge resource examines all known attacks on Bluetooth security mechanisms and their implementations, demonstrating how some of these known weaknesses can be avoided with appropriate defensive measures. The book presents concrete examples of how to design security solutions for some Bluetooth applications and products built on these applications. You find real-world case studies including technical algorithms, mechanisms and protocols, and security architectures. These architectures offer valuable guidelines for use in building Bluetooth and non-Bluetooth-specific security mechanisms.
