Wireless

Originally published in 1931, this book was written to provide an account of wireless theory and practice for competent electrical engineers without knowledge of high-frequency phenomena. The text discusses numerous aspects of wireless telegraphy and telephony, incorporating information on key principles and direct engineering application. Illustrative figures and detailed notes are also included. This book will be of value to anyone with an interest in the development of wireless technologies, engineering and the history of science.1.
