  • The Stage Is Set
    The Stage Is Set: Developments before 1900 Leading to Practical Wireless Communication Darrel T. Emerson National Radio Astronomy Observatory1, 949 N. Cherry Avenue, Tucson, AZ 85721 In 1909, Guglielmo Marconi and Carl Ferdinand Braun were awarded the Nobel Prize in Physics "in recognition of their contributions to the development of wireless telegraphy." In the Nobel Prize Presentation Speech by the President of the Royal Swedish Academy of Sciences [1], tribute was first paid to the earlier theorists and experimentalists. “It was Faraday with his unique penetrating power of mind, who first suspected a close connection between the phenomena of light and electricity, and it was Maxwell who transformed his bold concepts and thoughts into mathematical language, and finally, it was Hertz who through his classical experiments showed that the new ideas as to the nature of electricity and light had a real basis in fact.” These and many other scientists set the stage for the rapid development of wireless communication starting in the last decade of the 19th century. I. INTRODUCTION A key factor in the development of wireless communication, as opposed to pure research into the science of electromagnetic waves and phenomena, was simply the motivation to make it work. More than anyone else, Marconi was to provide that. However, for the possibility of wireless communication to be treated as a serious possibility in the first place and for it to be able to develop, there had to be an adequate theoretical and technological background. Electromagnetic theory, itself based on earlier experiment and theory, had to be sufficiently developed that 1.

  • The Story of Nathan B. Stubblefield, Pioneer Wireless Experimenter

DESCRIPTORS Communication (Thought Transfer); *Communications; *Radio; *Radio Technology; *Technological Advancement; United States History IDENTIPIERS *Stubblefield (Nathan B); Wireless Telephone ABSTRACT This paper discusses the contribution of Nathan B. Stubblefield of Murray (Calloway County), Kentucky, to the field of broadcast history and ascribes to him the intention of wireless voice commnnication. In 1888, Stubblefield was granted a patent on a mechanical or "knocking" telephone which was subsequently installed in towns in several states including Kentucky, Indiana, Mississippi, and North Carolina, However, by 1889, the Bell telephone, an electrical device far superior in sound quality and distance, had worked its way westward into Stubblefield's home territory, and soon resulted in reducing the Stubblefield phone to intercom use. In 1908, Stubblefield patented a second kind of wireless telephone--a system based on induction--and one that is used by many to credit him with the invention of modern radio broadcasting. However, Stubblefield's attempts to market his wireless telephone were unsuccessful and soon other devices surpassed his inventions. Biographic information about Stubblefield is included.

    1 History Introduction UWB – ultra-wideband – is an unconventional type of radio, but to under- stand a variation on the convention, we must grasp the basics of traditional radio. When most people hear the word “radio” they think of the small device that brings music and news into their homes and automobiles. That is true, but radio has many forms. In fact, many common devices that perform some function in a wireless mode are a variety of radio, such as wireless baby monitors, wireless Internet connections, garage door openers, and mobile or cell phones. In this chapter, we introduce the basics of traditional radio. We follow the history of the development of wireless – to be dubbed radio at the start of the broadcast era – from its inception as crude wideband spark sig- nals, through its relentless march towards narrowband-channelized solu- tions. Finally, we see its resurgence as the modern “wireless.” History reveals that the march towards narrowband admits several instances in which wideband signaling has significant advantages over narrowband techniques. The present evolution to UWB is but an inevitable step in the evolution of wireless and radio. 1.1 The BasicsCOPYRIGHTED of Radio MATERIAL Radio is the art of sending and receiving electromagnetic signals between transmitters and receivers wirelessly, as depicted in Figure 1.1. Radio requires transmitters for generating signals, and receivers to translate the received information. Both use antennas for sending the signals as Ultra-Wideband Radio Technology Kazimierz Siwiak and Debra McKeown 2004 John Wiley & Sons, Ltd ISBN: 0-470-85931-8 2 Ultra-Wideband Radio Technology Figure 1.1 A basic radio link includes a transmitter, waves propagating and filling space, and a receiver [McKeown 2003].

It should be pointed out that the history of origin and developments of wireless (or radio) communications, wireless as presented here is planned on the basis of three according to the following pattern: it gives credit to some of the different types of discoveries: those that made it possible, scientists who performed the initial observations and the understanding of electric and magnetic phenomena; it mentions those that made it realistic, and those that provided quality [ 1]. the experiments and inventions carried out towards the evolution Because of all these issues, it is not easy to objectively state of scientific and engineering models; and focuses on the who the Father of Radio was. Often, the invention of radio is implementation of practical wireless systems. The presentation delegated to one or two persons, the names of whom vary leads us to conclude that the invention and development of from country to country, depending on the country of origin of wireless/radio system can neither be credited to one individual nor to one specific country.

    _ FARM BROADCASTING The First Sixty Years JOHN C. BAKER The Iowa State University Press, Ames 070, ti5191,3 1940 JOHN C. BAKER has worked with or known most of the who have worked in farm broadcasting 406 men and women since the twenties. He was born in Indiana in the year that Admiral Peary reached the North Pole (1909), grew up in apple orchard, and received an undergraduate degree in agriculture from Purdue University in 1930. He made his first broadcast to farmers over the Purdue radio station, WBAA, when he was assistant extension editor, 1930-1931, and continued for four years as radio az extension editor in Massachusetts. Then followed two periods each on WLS, Chicago, and in the radio service of the U.S. Department of Agriculture, where he took part . in the "National Farm and Home Hour" on NBC and "The American Farmer" on ABC. In the fifties and sixties he was an information officer in the U.S. Department of 1980 Agriculture and the Bureau of the Census. He has been a member of the farm broadcasters' organization, under its several names, since its first na- tional convention in 1945. He and his wife, Mary, live in Arlington, Virginia, "close enough but not too close" to their daughter, son, and five grandchildren. © 1981 The Iowa State University Press. All rights reserved.

  • Just Who Did Invent Radio?
    Just Who Did Invent Radio? If you're sure you know, the answer may surprise you. Glen E. Zook, K9STH (Originally published in the July 1996, issue of 73 Magazine) Copyright 1996 by author There's a lot of interesting history in the realm of radio and its child, television. The players include inventors, businessmen, performers, and lots of other people. Unfortunately, the vast majority of this information has not been made available to the masses! Marconi First of all, ask the average American, "Who invented radio?" If they know at all, the reply will usually be "Marconi." For most of my life, and that of my parents and grandparents, the inventor of radio has been, according to all the history books, Guglielmo Marconi, born in Bologna, Italy, on April 25, 1874. Marconi was the son of a very successful Italian businessman with extensive business ties to Great Britain. Marconi was interested in wireless telegraphy (radio) from an early age, and conducted experiments on his father's estate starting in June of 1895. Later that year he was able to send messages up to one-and-a-half miles. Seeing the commercial potential of communications with ships, the 22-year-old Marconi went to England where, in 1896, he was granted his first patent on radio communications. Later, with the help of his father, Marconi contacted a number of influential British businessmen, and the Marconi Company was formed to develop wireless communications. Until about 1920, this company dominated the radio scene worldwide. Lodge and Fessenden However, several years before Marconi even started experimenting, as early as 1888, Oliver Lodge (later Sir Oliver), a professor at Liverpool University, was conducting experiments in wireless telegraphy.
