Understanding WAP : Wireless Applications, Devices and Services

OFDMA System Analysis and Design

Here's a unique resource that provides you with an up-to-date understanding of how to plan, analyze, and design next-generation broadband wireless networks. This comprehensive book includes all the necessary background information needed to fully understand the material and places emphasis on practical engineering know-how that can be readily applied to designing OFDM-based systems. You find detailed discussions on everything from the physical and media access control layers, to QoS and security functions. Rather than just offering simple explanations of standards, this invaluable book takes a close look at live, real-world systems, explaining how the technical features work and why they were adopted. Moreover, the author includes his own design frameworks and rules that have been developed through his own extensive research and experience. This comprehensive reference is supported with over 170 illustrations and more than 250 equations.

MOBILE COMPUTING

This textbook provides students with a sound foundation in the concepts and applications of mobile computing. It discusses all the relevant topics in mobile computing in a clear and straightforward style. The book begins with an introduction to the subject and then moves on to describe the fundamentals of wireless communication including a brief description of different modulation techniques. The text includes coverage of second generation (2G) cellular network together with its two important implementation standards GSM & IS-95; it also discusses WLL and WLAN. In addition, it presents a variety of data services available in the domain of mobile computing with other relevant issues. Finally, it gives a brief on UMTS, a representative of the third generation (3G) of cellular networks. The fundamental tenets of mobile computing, such as mobility management, channel assignment, protocols at air interface, and system design are carefully covered for all categories of wireless networks described here. A perfect balance between theoretical aspects of mobile computing and its implementation standards has been maintained throughout the book. Many examples and exercises are included, which will help students prepare for examinations. The book is intended primarily for students of B.E./B.Tech. of Computer Science and Engineering, Information Technology, Electronics and Communication Engineering, and related disciplines. It will also be useful to the students of BCA/MCA and B.Sc./M.Sc. (Computer Science/Electronics).
