Towards a location aware mobile ad hoc sensor A Systems Engineering Approach to the Wireless Network Information The second edition of the internationally respected text book brings readers fully up to date with the myriad of wireless communications development. Readers can learn about the latest applications in fields such as ad hoc sensor networks, home networks, and wireless positioning. Wireless Network Information systems engineering approach to take: the technical topics presented within the context of how they fit into the ongoing development of new systems and services, as well as recent developments in national and international spectrum allocations and standards. The authors have organized a myriad of current and emerging wireless technologies into logical categories: * Introduction to Wireless Networks presents an up-to-time-evolution discussions cellular industry from analog to 2G mobile technology, 3G, and 4G, and the emergence of WLAN and WPAN as an ad hoc broadband network * Characteristics of Radio Propagation includes new coverage model for space-time channel, MIMO, and UWB communications and wireless network geolocation * Modem Design offers new description of space-time coding, MIMO antenna systems, UWB communications, and multi-user detection and interference cancellation techniques used in CDMA networks * Network Access and System Aspects incorporate new chapter on UWB system and geolocations RF, with a thorough revision of the wireless access techniques and wireless systems and standards Exercises that focus on real-world problems provided at the end of each chapter. Mix of tasks, which include computer project and questionnaire in addition to the traditional set of problems, help the reader focus on key issues and develop the skills they need to solve real engineering problems.
