Microwave relay mast, Greece. Microwave transmission is the transmission of information or energy by microwave radio waves. Large transcontinental microwave relay networks, consisting of chains of repeater stations linked by line-of-sight beams of microwaves cover much of Europe and America, relaying long distance telephone traffic and television programs between cities. The microwave spectrum is used by many new telecommunication technologies such as wireless networks, and direct-broadcast satellites which broadcast television and radio directly into consumers' homes.
