Wireless LANs have become mainstream over the last few years. What started out as cable replacement for static desktops in indoor networks has been extended to fully mobile broadband applications involving moving vehicles, high-speed trains, and even airplanes. This book is designed to appeal to a broad audience with different levels of technical background and can be used in a variety of ways: as a first course on wireless LANs, as a graduate-level textbook, or simply as a professional reference guide. It describes the key practical considerations when deploying wireless LANs and equips the reader with a solid understanding of the emerging technologies. The book comprises 38 high-quality contributions from industry and academia and covers a broad range of important topics related to 802.11 networks, including quality of service, security, high throughput systems, mesh networking, 802.11/cellular interworking, coexistence, cognitive radio resource management, range and capacity evaluation, hardware and antenna design, hotspots, new applications, ultra-wideband, and public wireless broadband.

Using Trolltech's Qt you can build industrial-strength C++ applications that run natively on Windows, Linux/Unix, Mac OS X, and embedded Linux–without making source code changes. With this book Trolltech insiders have written a start-to-finish guide to getting great results with the most powerful version of Qt ever created: Qt 4.1.

Using C++ GUI Programming with Qt 4 you'll discover the most effective Qt 4 programming patterns and techniques as you master key technologies ranging from Qt's model/view architecture to Qt's powerful new 2D paint engine. The authors provide readers with unparalleled insight into Qt's event model and layout system. Then, using realistic examples, they introduce superior techniques for everything from basic GUI development to advanced database and XML integration.

Written by recognized authorities in the field, this book provides engineers, computer scientists, and others with a working familiarity with the theory and contemporary applications of Global Positioning Systems (GPS), Inertial Navigational Systems, and Kalman filters. Throughout, the focus is on solving real-world problems, with an emphasis on the effective use of state-of-the-art integration techniques for those systems, especially the application of Kalman filtering. To that end, the authors explore the various subtleties, common failures, and inherent limitations of the theory as it applies to real-world situations, and provide numerous detailed application examples and practice problems, including GPS-aided INS, modeling of gyros and accelerometers, and WAAS and LAAS.
