Microwave radio is a popular unbounded medium that uses radio signals to transmit large volumes of voices and data traffic. The tall towers with large horns and/ or disk antennas that we see across the country are devices for line-of-sight (LOS) ground transmission and transmission between ground station and satellites. This is how it works: the antenna on a microwave radio converts the short wavelength of the transmitted signal into a beam that provides a much greater signal strength at the receiving end, without requiring increased transmitter power. Microwave radios are useful for connecting networks that are only short distances apart.
