Wireless communication is among technology’s biggest contributions to mankind. Wireless communication involves the transmission of information over a distance without help of wires, cables or any other forms of electrical conductors. The transmitted distance can be anywhere between a few meters (for example, a television’s remote control) and thousands of kilometres (for example, radio communication). Wireless technology has become the most exciting area in telecommunications and networking. The rapid growth of mobile telephone use, various satellite services, and now the wireless. Internet and wireless LANs are generating tremendous changes in telecommunications and networking. This book provides a comprehensive technical guide covering fundamentals, recent advances and open issues in wireless communications and networks to the readers. This book focuses on the current hottest issues from the lowest layers to the upper layers of wireless communication networks and provides real-time research progress on these issues. The book intends to serve as a valuable tool for students, educators, scientists, faculty members, researchers, engineers and research strategists in these rapidly evolving fields and to encourage them to actively explore these broad, exciting and rapidly evolving research areas.
