Because solar activity can have a certain influence on the ionosphere, the wavelength transmitted in the mode also changes along with the intensity of solar activity; the other is ground wave transmitted by being attached to the ground surface. This transmission mode suffers from loss due to the influence of the relative dielectric constant and conductivity. The relative dielectric constant and the conductivity of the seawater are relatively large, so the loss is small, and the seawater has more application in maritime communication.
