What is the typical frequency range for low-frequency (LF) signals?

The typical frequency range for low-frequency (LF) signals actually falls between 30 kHz to 300 kHz. This range is defined within the broader classification of radio frequencies. LF signals are typically used in various applications, such as navigation and maritime communication, as they can effectively penetrate the atmosphere and travel long distances, relying on ground wave propagation.

Understanding the classification of radio frequencies is essential for distinguishing between the different bands. The lower frequencies, such as those within the LF range, have unique properties, including their ability to follow the curvature of the Earth and propagate over great distances, which is beneficial for certain types of communication systems.
