Wireless Signal Propagation

Wireless Signal Propagation? Wireless communications systems are composed of one or more “Antenna Sites”, “Tower Sites”, or “Cell Sites”. … Wireless signal propagation is the movement of these radio waves (which move at the speed of light) to and from these sites and devices.

Radio waves can propagate from transmitter to receiver in four ways: through ground waves, sky waves, free space waves, and open field waves. Ground waves exist only for vertical polarization, produced by vertical antennas when the transmitting and receiving antennas are close to the surface of the earth.
