and carried out the transmission of news over a considerable distance in his laboratory in March 1895. However, for the entire following year, he faced obstacles to conducting more extensive experiments. Fortunately, this interruption did not last long. Within a year, Tesla had new equipment, and by the end of 1896, he established a small radio station near New York from which he transmitted wireless signals without wires over distances of 35 kilometers and more. These experiments were mentioned in various electrical magazines in America, and we specifically quote from the Electrical Review of July 9, 1897, as follows: â... Various experiments were conducted to demonstrate the possibility of wireless transmission of news, but it was only Nikola Tesla who succeeded in creating a theory and experimentally verifying it, thus proving that wireless communications are not only possible but, in fact, there are no distances where they would not be possible. After conscientious and persistent work of six years and more, aware of his goal, Tesla achieved results that give us the ability to predict the future... Tesla set up both a transmitting and receiving radio station and carried out the transmission of news over long distances regardless of earth currents, obstacles, and direction. This was achieved with incredibly low energy consumption... In 1891, Tesla predicted the results of wireless transmission of news, which he has now realized. He began with a frequency of 10,000 cycles per second and perfected his apparatus to such an extent that he is now able to produce oscillations of 2 million cycles per second and more.â This quote serves as documentation that Tesla indeed conducted significant experiments, which, based on the principle of resonance and the use of high-frequency currents of around 2 million cycles per second (corresponding to a wavelength of about 150 meters), practically laid the foundations for radio technology. Details of Teslaâs experiments are described in his fundamental patents of September 2, 1897, protecting the resonant circuitry and apparatus on the transmitting and receiving radio station for all types of wireless transmissions (patents 645576 and 649621).
This announcement proves the following historical facts:
- Tesla was the first to conduct long-distance wireless signal transmissions near New York, involving representatives of science, using high-frequency currents of 2 million cycles produced by his electric oscillators, as described in numerous patents and lectures.
- Experiments were carried out in the transmitting and receiving radio stations based on Teslaâs plan published several years ago, which includes the antenna-ground system in both stations.
- Both the transmitting and receiving stations utilized high-frequency current circuits that operated on the principle of resonance, protected by patents 645 576 and 649 621.
- For frequencies of 2 million cycles and corresponding wavelengths of 150 meters, the curvature of the earth, terrain disturbances, distance, and direction posed no obstacles.
- The energy consumption in the conducted experiments was measured and determined to be negligible.
