TELECOMUNATIONS AND METERIOLOGY Telecommunication in the modern era is the science and practice of transmitting information by electromagnetic means. In earlier times, telecommunications involved the use of visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags, and optical heliographs, or audio messages such as coded drumbeats, lung-blown horns, and loud whistles. In modern times, telecommunications involves the use of electrical devices such as the telegraph, telephone, and teleprinter, as well as the use of radio, microwave transmission towers, fiber optics, orbiting satellites and the Internet, which is a vast world-wide computer network. A revolution in wireless telecommunications began in the first decade of the 1900s with pioneering developments in radio communications by Nikola Tesla and Guglielmo Marconi. Marconi won the Nobel Prize in Physics in 1909 for his efforts. Other highly notable pioneering inventors and developers in the field of elec Less
