Line of Sight Propagation
In line of sight (LOS) radio communications, the main route is the direct path between the transmitter and the receiver considering the curvature of radiowave trajectory. In Chap. 2, we discussed the general phenomena such as free space loss (FSL) , gas and vapor loss, Fresnel radius, K-factor, and other mechanisms such as diffraction, reflection, and refraction. In this chapter we will introduce specific issues related to the LOS wave propagation.
