Paperback. Condición: New. Print on Demand. This book documents the history of wireless telephony, a fascinating technology that allowed humans to communicate over great distances for the first time. It traces the development of the technology, from its humble beginnings with the photophone to its culmination in the arc lamp, a…speaking device that could transmit sound waves over several kilometers. The author recounts the pivotal role played by the discovery of the speaking arc by Simon in 1897 and explores the subsequent work of Simon and the author, who adapted the technology for practical use. The book delves into the technical details of the speaking arc, explaining how it converts electrical signals into sound waves, and discusses the optimal conditions for its operation. It also examines the limitations and challenges of wireless telephony, including the effects of atmospheric conditions and the need for highly sensitive receivers. Ultimately, this book provides a comprehensive overview of the development of wireless telephony, offering valuable insights into the history and evolution of this groundbreaking technology.
