Which frequency range defines the LF band?

Explanation:
Low Frequency is defined as 30 kHz to 300 kHz. This part of the spectrum sits at the low end, yielding long wavelengths (roughly 10 km down to 1 km), which favors ground-wave propagation over long distances and supports lower data rates. Because of these characteristics, LF is used for specialized, long-range communications rather than high-bandwidth links. The other ranges correspond to different bands: 3–30 kHz is typically considered Very Low Frequency, 300 kHz–3 MHz is Medium Frequency, and 30–300 MHz is Very High Frequency. Therefore, the LF band is 30 to 300 kHz.
