In radio communications, the line of sight (LOS) is the direct, unimpeded path that an RF (radio frequency) signal takes from the transmitter to the receiver. Both the curvature of the Earth and the antenna heights can influence this line of sight. The understanding of radio line of sight is not only crucial in telecommunications but also in the broader fields of physics and engineering.

The formula to calculate the radio line of sight is given by:
The specific person who derived this formula is not easily attributed, as it emerged from a broader scientific understanding of Earth's curvature and radio wave propagation. It has been refined over the years as a collective effort of scientists and engineers in the field of radio communication and telecommunication engineering.
In real-life, the radio line of sight concept is essential in setting up any form of wireless communication. For example, mobile networks, radio stations, WiFi networks, and satellite communications all require a clear understanding of the line of sight for proper installation and maximum signal coverage.
Guglielmo Marconi, a pioneer of long-distance radio transmission, made significant contributions to the field of radio communication. His work in the early 20th century laid the foundation for the establishment of numerous wireless communication systems, including the concept of the line of sight in radio communication.
Understanding the concept of radio line of sight is fundamental for efficient radio communication setup. This knowledge allows us to take full advantage of wireless technologies, providing better signal coverage and reliable communication. As we continue to push the boundaries of wireless communications, the understanding of these fundamental principles will continue to be crucial.
