Jurandir Primo, PE
This course is an actual and important basic knowledge of RF & Wireless Technology – Wi-Fi and Bluetooth Principles, a very important section of technology that deals with the standards, development and construction of wireless devices. The radio-frequency began with the very important work of the Scottish scientist James Clerk Maxwell, in his researches on the spatial electromagnetic waves, and continued by the German physicist Heinrich Rudolf Hertz, which constructed the first short dipole antenna and a type of spark oscillator, with which he really demonstrated the existence of the space radio waves.
Then, 10 years later, Hertz's proof of the existence of the airborne electromagnetic waves led to an explosion of experimentation with a new form of electromagnetic radiation, which was called “Hertzian waves”. Then, many researchers, such as Oliver Lodge, Ferdinand Braun, and Guglielmo Marconi employed radio waves in the first wireless telegraphy communication systems, leading to radio broadcasting, and later television. In 1909, Braun and Marconi received the Nobel Prize in physics for their “contributions to the development of wireless telegraphy”. In 1930, the SI unit “hertz” (Hz) was established in honor of Heinrich Hertz, by the International Electrotechnical Commission for “frequency”, an expression of the number of times that a repeated event occurs per second.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
