Shannon, “A Mathematical Theory of Communication”, Vol. 27, pp. 379–423, 623–656, July, October 1948. During the development of radio, many scientists and inventors contribute to radio technology and electronics.

The mathematical work of James Clerk Maxwell during the 1850s had shown the relationship of different forms. Electromagnetic radiation including the possibility of invisible airborne waves (later called “radio waves”). In his classic physics experiments of 1888, Heinrich Hertz proved Maxwell’s theory by transmitting radio waves. A spark-gap transmitter, and detect them by using simple electrical devices.

Other physicists experiment with these new waves and in the process develope devices for transmitting and detecting them.

In 1895, Guglielmo Marconi began work on a way to adapt the known methods of transmitting and detecting these .”Hertzian waves” into a purpose built commercial wireless telegraphic system. Early on, he sent wireless signals over a distance of one and a half miles. In December 1901, he sent wireless waves that were not affected by the curvature of the Earth.

Power & Energy engineering deals with the generation, transmission, and distribution.

Electricity as well as the design of a range of related devices. These include transformers, electric generators, electric motors, high voltage engineering, and power electronics. In many regions of the world, governments maintain an electrical network called a power grid that connects. A variety of generators together with users of their energy. Users purchase electrical energy from the grid, avoiding the costly exercise of having to generate their own.

Power engineers may work on the design and maintenance of the power systems that connect to it.

Such systems are call on-grid power systems and may supply. The grid with additional power, draw power from the grid, or do both. Power engineers may also work on systems that do not connect to the grid. Which in some cases are preferable to on-grid systems. The future includes Satellite controlled power systems, with feedback in real time to prevent power surges and prevent blackouts.
