[0002] Medium wave communication is radio communication using electromagnetic waves with a wavelength of 1000 to 100m. During the day, the D layer of the ionosphere strongly absorbs medium waves, making it difficult to use sky waves for propagation, and can only rely on ground waves for propagation. At night, the D layer disappears, the electron density of the E layer decreases, the altitude rises, the absorption decreases, and the electromagnetic waves can be reflected by the E layer. At this time, medium waves are propagated by sky waves in addition to ground waves. During the propagation process, the simultaneous existence of ground waves and sky waves can sometimes cause difficulties in reception, so the transmission distance will not be very far, generally a few hundred kilometers.
