Communication Tower With Microwave Parabolic Antenna : (pix Sanjiv Shukla) Royalty-Free Stock Image

Microwave transmission is the transmission of information by electromagnetic waves with wavelengths in the microwave frequency. Microwave signals are normally limited to the line of sight, so long-distance transmission using these signals requires a series of repeaters forming a microwave relay network. It is possible to use microwave signals in over-the-horizon communications using tropospheric scatter. This is achieved by installing parabolic and other antennae on high communication towers.
