    Shadowing effects are defined as the effects of received signal power fluctuations due to obstruction between the transmitter and receiver. Therefore, the signal changes as a result of the shadowing mainly come from reflection and scattering during transmittal. The shadowing effects will also result in the wave lights bending, that is, the transmission does not follow a straight line.
