Longwave broadcasting is a method of transmitting radio signals using long wavelengths, typically between 30 kHz and 300 kHz. This type of broadcasting allows signals to travel long distances, often beyond the horizon, by following the curvature of the Earth. It is commonly used for AM radio stations and maritime communication. One of the key advantages of longwave broadcasting is its ability to provide reliable coverage in rural and remote areas. Countries like France and United Kingdom utilize longwave frequencies for national radio services, ensuring that listeners can access broadcasts even in challenging conditions.
