A wireless network refers to a computer network that utilizes wireless data connections among network nodes. They are unique as they can connect devices, services, people and applications to a network, without being bound to any wired hardware. Wireless networking enables businesses to create local area networks (LANs), wide area networks (WANs), and metropolitan area networks (MANs) without using cables. A wireless LAN reduces the cost of installing LAN cabling and makes changes to network structure and its relocation easier. Wireless local area networks (WLANs), terrestrial microwave networks, wireless sensor networks, cell phone networks, and satellite communication networks are a few examples of wireless networks. They are a widespread choice for telecommunications, and residential and commercial networks. Various applications of wireless networking include television remote controls, cell phones, computer interface devices, security systems, Wi-Fi, wireless power transmission, and a variety of wireless communication based projects. This book aims to shed light on the theory and applications of wireless networks. It will serve as a reference to a broad spectrum of readers.

An antenna is the interface between the radio waves propagating through space and the electric currents flowing in metal conductors. It is utilized in conjunction with a transmitter or receiver. It can be built to transmit and receive radio waves preferentially in one direction or equally in all horizontal directions. Antennas are necessary for wireless communication systems to function properly at both the transmitter and receiver ends. The rapid development of wireless communication systems has in turn led to the development of innovative antenna technologies such as meta-material antennas, diversity antennas, smart antennas, and various software-defined antenna systems that are making their way onto the market to support modern wireless communication. Smart antenna is an antenna array with digital signal processing algorithms, which identify spatial signatures, which in turn are used by the smart antenna to calculate beamforming vectors that are used to track and locate the antenna beam on a mobile or target. This book aims to shed light on the concept of smart antennas and wave propagation for wireless communication. It also elucidates new techniques and their applications. This book aims to equip students and experts with the advanced topics and upcoming concepts in this area.
