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. NY PE & PLS: You must choose courses that are technical in nature or related to matters of laws and ethics contributing to the health and welfare of the public. NY Board does not accept courses related to office management, risk management, leadership, marketing, accounting, financial planning, real estate, and basic CAD.
