Wireless communication refers to the transfer of information or power between two or more points that are not directly connected by an electrical conductor. Such communication is achieved with the help of radio waves. These waves cover a wide range of distance, from a few meters in the case of Bluetooth to as far as millions of kilometers in the case of deep-space radio communications. Wireless communication can also be achieved via free-space optical communication, sonic waves and electromagnetic induction. Various portable, fixed and mobile applications allow such communication to be established. GPS units, satellite television, radio receivers, cordless telephones and broadcast television are examples of systems that operate on wireless technology. This book outlines the process and applications of wireless communications in detail. It is a valuable compilation of topics, ranging from the basic to the most complex advancements in this field. For someone with an interest and eye for detail, this book covers the most significant topics in the field of wireless communication.
