![]() Radio propagation can be described as the way in which radiofrequency waves travel or propagate when they are transmitted from a transmitter to receiver. Ground wave propagation utilizes radio waves in the range of 50 kHz to 250 kHzĪpplications such as wireless computer networks, communications satellites, radio navigation, amateur radio communications, and international shortwave broadcasters all use radio waves, which is why signal propagation can be called radio wave propagation. ![]() The factors that affect ground wave propagation are the nature of the ground, weather, polarization, and signal frequency. Ground waves are divided into three components: surface waves, direct waves, and earth reflected waves. The electromagnetic spectrum in the frequency range from 3 kHz up to 300 GHz can be called the radio spectrum.
