Abstract: The field of wireless networks systems has witnessed tremendous growth in recent years causing it to become one of the fastest growing segments of the telecommunications technology. As wireless networks evolve with increasing size and profitability, they will be able to integrate with other wireless technologies enabling them to support mobile computing applications and perform as efficiently as wired networks. Due to the difficulties posed by the wireless transmission medium and the increasing demand for better and cheaper services, the area of wireless networks is also an extremely rich field for research and development.
This tutorial provides in-depth coverage of the wide range of wireless technological alternatives offered today. It covers the fundamental techniques in the design, operation, and evaluation of wireless networks. It introduces the basic topics involved with wireless systems such as the electromagnetic spectrum physics of propagation, modulation multiple access and performance enhancement techniques, and cellular and ad-hoc concepts. It also presents the First Generation (1G) cellular systems, current Second Generation (2G) systems architectures supporting voice and data transfer and discusses the fast evolving world of Third Generation (3G) mobile networks systems. We will also, provide a vision of 4G and beyond mobile and wireless systems and describe satellite-based systems, fixed wireless systems, wireless LANs, wireless ATM and ad-hoc systems, Personal Area Networks (PANs) and security issues in wireless networks. Techniques for modeling simulation of wireless networks along with case studies will be covered as well. This tutorial provides engineers, researchers, faculty members, and graduates with an update of all of the key areas of wireless networks systems.
