Computer networks which use wireless data connections for transfer of information between two network nodes are known as wireless networks. Most of the wireless networks make use of radio waves for transferring data between different nodes of a network. Some of the other technologies employed for wireless communication are terrestrial microwaves, free space optical communication and satellites. These networks can be broadly categorized into wireless personal area networks (WPAN), wireless local area networks (WLAN), wireless ad hoc networks (WANET), cellular networks, global networks and space networks. A few examples of cellular networks are global systems for mobile communication, personal communication service and digital advanced mobile phone service. This book unfolds the innovative aspects of wireless communication networks and systems which will be crucial for the holistic understanding of the subject matter. It is an essential guide for both academicians and those who wish to pursue this discipline further. Coherent flow of topics, student-friendly language and extensive use of examples make this textbook an invaluable source of knowledge.
