Radio From the Beginning to the Evolution of Todays...

Radio: From the Beginning to the Evolution of Todays Technology Broadcast media has been around for many, many years and the grandfather of them all is the radio. The radio has been around for so long and has become such a prominent fixture in our society that we take it for granted. Every day many of us are exposed to some form of radio without realizing it. From the beginning of its technology, other forms of media have evolved also; television, wireless internet, and cellular phones, which most of us use daily.

The theory Maxwell had was with light, but 15 years later German physicist Heinrich Hertz used the same principle with electricity. Hertz found that by sending an electrical pulse to a capacitor and short-circuited the capacitor through a spark gap, the electrical pulse rushed past the neutral point building an opposite charge in the capacitor sending it back and continuing to fall back and forth creating an electrical oscillation. During this process, some of the energy escaped into the air causing electromagnetic waves. Hertz measured these waves and many of the properties as well as wavelengths and velocity. These pulses are measured in cycles per second or hertz; 1 kilohertz (kHz) is 1000 per cycle, 1 megahertz (MHz) is 1 million cycles per sec, and 1 gigahertz (GHz) is 1 billion cycles per sec (Encarta Enc yclopedia, 2007). Wireless radio technology was not introduced until 1893 when Nikola Tesla gave a demonstration of wireless transmission in St. Louis, Missouri. Addressing the Franklin Institute in Philadelphia and the National Electric Light Association, Tesla described in detail the principles of radio communication. The system he used had a more sensitive electromagnetic receiver that was unlike the ones used by GuglielmoShow MoreRelatedRadio: from the Beginning to the Evolution of Todays Technology1850 Words   |  8 PagesRadio: From the beginning to the evolution of today s technology Broadcast media has been around for many, many years and the grandfather of them all is the radio.

The conference was only for American government agencies, those present consisted of the U.S. Navy, the Department of Agriculture, and Army s Signal Corp. The reason for this conference is to elect a representative from each government agency and to begin preparations of coordinating each agency with the others, and the development of radio services. The 1904 Roosevelt Board Report gave the U.S. Navy the powering control over government radio, and placed many significant limitations on commercial radio. In 1906 the Berlin conference reconvened with an agreement, International Wireless Telegraph Convention. This agreement was adopted on November 3, 1906, but would not come into effect until July 1, 1908. Even though the United States signed this agreement in 1906, the U.S. Senate did not endorse the Berlin Convention until 1912. Roosevelt ordered the convention effective on May 25, 1912. The United States passed a radio regulation law lasting from 1911 to 1927. These regulations written by the Department of Commerce s Bureau of Navigation, placed three inspectors to insure that ocean going ships carried radio equipment. A Radio Inspector was placed at each major port, which expanded the inspectors to nine (White, n.d.).
