It is the story of great men--Morse, Thomson, Bell, Marconi, and others--and how, with the aid of men like Field, Vail, Catty, Pupin, the scientist, and others in both the technical and commercial fields, they succeeded in flashing both messages and speech around the world, with wires and without wires. It is the story of how the thought of the world has been linked together by those modern wonders of science and of industry--the telegraph, the submarine cable, the telephone, the wireless telegraph, and, most recently, the wireless telephone. The story opens with the primitive methods of message-sending by fire or smoke or other signals. The life and experiments of Morse are then pictured and the dramatic story of the invention and development of the telegraph is set forth. The submarine cable followed with the struggles of Field, the business executive, and Thomson, the inventor and scientific expert, which finally culminated in success when the _Great Eastern_ landed a practical cable on the American coast. The early life of Alexander Graham Bell was full of color, and I have told the story of his patient investigations of human speech and hearing, which, finally culminated in a practical telephone. There follows the fascinating story of Marconi and the wireless telegraph. Last comes the story of the wireless telephone, that newest wonder which has come among us so recently that we can scarcely realize that it is here. An inner view of the marvelous development of the telephone is added in an appendix. The part played by the great business leaders who have developed and extended the new inventions, placing them at the service of all, has not been forgotten. Not only have means of communication been discovered, but they have been improved and put to the widest practical use with remarkable efficiency and celerity. The stories of these developments, in both the personal and executive sides, embody the true romance of the modern business world. The great scientists and engineers who have wrought these wonders which have had so profound an influence upon the life of the world lived, and are living, lives filled with patient effort, discouragement, accomplishment, and real romance. They are interesting men who have done interesting things. Better still, they have done important, useful things. This book relates their life stories in a connected form, for they have all worked for a similar end. The story of these men, who, starting in early youth in the pursuit of a great idea, have achieved fame and success and have benefited civilization, cannot but be inspiring. They did not stumble upon their discoveries by any lucky accident. They knew what they sought, and they labored toward the goal with unflagging zeal. Had they been easily discouraged we might still be dependent upon the semaphore and the pony express for the transmission of news. But they persevered until success was attained, and in the account of their struggle to success every one may find encouragement in facing his own tasks. One can scarce overestimate the value of modern methods of communication to the world. So much of our development has been more or less directly dependent upon it that it is difficult to fancy our situation without the telegraph and telephone. The diligence with which the ancients sought speedy methods for the sending of messages demonstrates the human need for them. The solution of this great problem, though long delayed, came swiftly, once it was begun. Even the simple facts regarding "Masters of Space" and their lives of struggle and accomplishment in sending messages between distant points form an inspiring story of great achievement. W.K.T. #MASTERS OF SPACE# I COMMUNICATION AMONG THE ANCIENTS Signaling the Fall of Troy--Marine Signaling among the Argonauts--Couriers of the Greeks, Romans, and Aztecs--Sound-signaling--Stentorophonic Tube--The Shouting Sentinels--The Clepsydra--Signal Columns--Indian Fire and Smoke Signals. It was very early in the history of the world that man began to feel the urgent need of communicating with man at a distance. When village came into friendly contact with village, when nations began to form and expand, the necessity of sending intelligence rapidly and effectively was clearly realized. And yet many centuries passed without the discovery of an effective system. Those discoveries were to be reserved for the thinkers of our age. We can understand the difficulties that beset King Agamemnon as he stood at the head of his armies before the walls of Troy. Many were the messages he would want to send to his native kingdom in Greece during the progress of the siege. Those at home would be eager for news of the great enterprise. Many contingencies might arise which would make the need for aid urgent. Certainly Queen Clytemnestra eagerly awaited word of the fall of the city. Yet the slow progress of couriers must be depended upon. One device the king hit upon which was such as any boy might devise to meet the simplest need. "If I can go skating tonight," says Johnny Jones to his chum, "I'll put a light in my window." Such is the simple device which has been used to bear the simplest message for ages. So King Agamemnon ordered beacon fires laid on the tops of Mount Ida, Mount Athos, Mount Cithaeron, and on intervening eminences. Beside them he placed watchers who were always to have their faces toward Troy. When Troy fell a near-by fire was kindled, and beacon after beacon sprang into flame on the route toward Greece. Thus was the message of the fall of Troy quickly borne to the waiting queen by this preconceived arrangement. Yet neither King Agamemnon nor his sagest counselors could devise an effective system for expediting their messages. Prearranged signals were used to convey news in even earlier times. Fire, smoke, and flags were used by the Egyptians and the Assyrians previous to the Trojan War. The towers along the Chinese Wall were more than watch-towers; they were signal-towers. A flag or a light exhibited from tower to tower would quickly convey a certain message agreed upon in advance. Human thought required a system which could convey more than one idea, and yet skill in conveying news grew slowly. Perhaps the earliest example of marine signaling of which we know is recorded of the Argonautic Expedition. Theseus devised the use of colored sails to convey messages from ship to ship of the fleet, and caused the death of his father by his failure to handle the signals properly. Theseus sailed into conflict with the enemy with black sails set, a signal of battle and of death. With the battle over and himself the victor, he forgot to lower the black flag and set the red flag of victory. His father, the aged AEgeus, seeing the black flag, believed it reported his son's death, and, flinging himself into the sea, was drowned. In time it occurred to the great monarchs as their domains extended to establish relays of couriers to bear the messages which must be carried.

  • HELIOGRAPH DESCRIPTION: the Heliograph Was a Communications Device Used to Transmit Messages Over Long Distances. It Uses a Mi
    HELIOGRAPH DESCRIPTION: The heliograph was a communications device used to transmit messages over long distances. It uses a mirror attached to a surveying device to direct a beam of light to a receiving station. Sunlight is used as the light source. Messages could be sent in any direction during daylight hours. If the sun was in front of the sender, the sun’s rays were reflected directly from the sender to the receiving station. If the sun was behind the sender, a secondary mirror was used to reflect the rays toward the receiving station. A keying system was used to generate the flashes required to transmit messages using the Morse Code. The distance that the signals could be seen depended on several variables. A clear line of sight was required and Heliograph at Fort because of the curvature of the earth, the heliograph stations were Bowie Visitor Center located on the highest convenient point. The clarity of the sky and the size of the mirrors were also significant factors. The maximum range was about 10 miles for each inch of mirror diameter. Under normal conditions using the naked eye, a flash could be seen for about 30 miles, much farther using a telescope. The speed at which messages could be sent was dependent on the proficiency of both the sender and the receiver. EARLY HISYORY: A forerunner to the heliograph, the heliotrope, was developed by Professor Carl Friedrich Gauss of the University of Gottingen in Germany. The heliotrope was used to direct a controlled beam of sunlight to a distant station to be used as a survey marker.

  • Early Forms of Long-Distance Communication
    EARLY FORMS OF LONG-DISTANCE COMMUNICATION In this material, you will learn about Telegraphy, Telephone and GSM architecture Before the development of the electric telegraph in the 19th century revolutionized how information was transmitted across long distances, ancient civilizations such as those in China, Egypt and Greece used drumbeats or smoke signals to exchange information between far-flung points. However, such methods were limited by the weather and the need for an uninterrupted line of sight between receptor points. These limitations also lessened the effectiveness of the semaphore, a modern precursor to the electric telegraph. Developed in the early 1790s, the semaphore consisted of a series of hilltop stations that each had large movable arms to signal letters and numbers and two telescopes with which to see the other stations. Like ancient smoke signals, the semaphore was susceptible to weather and other factors that hindered visibility. A different method of transmitting information was needed to make regular and reliable long-distance communication workable. Did You Know? SOS, the internationally recognized distress signal, does not stand for any particular words. Instead, the letters were chosen because they are easy to transmit in Morse code: "S" is three dots, and "O" is three dashes. The Electric Telegraph In the early 19th century, two developments in the field of electricity opened the door to the production of the electric telegraph. First, in 1800, the Italian physicist Alessandro Volta (1745-1827) invented the battery, which reliably stored an electric current and allowed the current to be used in a controlled environment. Second, in 1820, the Danish physicist Hans Christian Oersted (1777-1851) demonstrated the connection between electricity and magnetism by deflecting a magnetic needle with an electric current.

  • Early Telecommunication and the Birth of Telegraphy in Malta
    Early Telecommunication and the Birth of Telegraphy in Malta Mario Aloisio [email protected] Abstract: This paper reviews the birth of telegraphy and its take-up in Malta before the advent of radio. The driving force behind the adoption of a number of signalling methods and the telegraph in Malta was the militia, but a means of effective communication was also important for trade and as a warning system against unwanted intruders. Foreign, diplomatic, and news correspondence became possible after submarine cables linking Malta to mainland Europe were laid in the 1860s. Keywords: Telecommunications; electric telegraph, semaphore, submarine cables Introduction he Maltese archipelago has been the focus of attention of many powers who, at different periods, sought to capture and rule the Tislands. The Carthaginians, Romans, Arabs, Normans, French, and British, among others, all left their mark on these tiny islands. The Knights Hospitaller, a military religious order of St John now known as the Knights of Malta, settled in Malta in 1530 when Emperor Charles V of Sicily offered it to them after they had been driven out of Rhodes by Suleiman I. In 1798 the last grand master of the knights surrendered to Napoleon when the latter captured Malta on his way to Egypt. The French occupation was brief, the British taking over just two years later. Malta was made a British colony in 1813 and became independent in 1964. In view of Malta’s strategic location and therefore its importance as a military base and a place for international trade, the knights of St Symposia Melitensia Number 10 (2015) SYMPOSIA MELITENSIA NUMBER 10 (2015) John built impressive forts and bastions and improved upon existing defence structures.

The code book constructed by Vail was optimized according to the statistical properties of English. In this study, we propose a new code book optimized for Turkish and demonstrate that it is information-theoretically possible to achieve about a 10% improvement throughout the coding of Turkish texts by means of our proposal. The outcomes of this might serve as a basis for potential (academic and/or applied) Turkish language-specific lossless data compression studies. Key words: Information theory, source encoding, Morse code, language statistics, data compression 1. Introduction Morse code is a method of transmitting textual information as a series of on–off signals (e.g. tones, lights, clicks), which can be directly interpreted by a skilled listener or observer. This listener or observer might be either a human individual with the knowledge of the code book, or special equipment in which the code book and its encoding/decoding rules are embedded.

The key innovation of the technology is the ability of ultra-low power devices to utilize nearby existing radio signals to communicate. As there is no need to generate their own ener- getic radio signal, the devices can benefit from a simple design, are very inexpensive and are extremely energy efficient compared with traditional wireless communica- tion. These benefits have made backscatter communication a desirable candidate for distributed wireless sensor network applications with energy constraints.

U., Lalitpur, Nepal Corresponding Email: [email protected] ABSTRACT In the recent days, Visible Light Communication (VLC), a novel technology that enables standard Light- Emitting-Diodes (LEDs) to transmit data, is gaining significant attention. However, to date, there is very little research on its deployment. The enormous and growing user demand for wireless data is placing huge pressure on existing Wi-Fi technology, which uses the radio and microwave frequency spectrum. Also the radio and microwave frequency spectrum is heavily used and overcrowded. On the other hand, visible light spectrum has huge, unused and unregulated capacity for communications (about 10,000 times greater bandwidth compared to radio spectrum). Li-Fi, the wireless technology based on VLC, is successfully tested with very high speed in lab and also implemented commercially. In the near future, this technology could enable devices containing LEDs, such as car lights, city lights, screens and home appliances, to form their own networks for high speed, secure communication. In this paper the performance analysis of Hadamard Coded Modulation (HCM) for Visible Light Communication (VLC) is carried out.
