11 Facts About Microwave relay

Microwave relay transmission is the transmission of information by electromagnetic waves with wavelengths in the microwave range of the electromagnetic spectrum.

Microwave radio relay is a technology widely used in the 1950s and 1960s for transmitting information, such as long-distance telephone calls and television programs between two terrestrial points on a narrow beam of microwaves.

Chains of microwave relay stations were used to transmit telecommunication signals over transcontinental distances.

Microwave relay stations were often located on tall buildings and mountaintops, with their antennas on towers to get maximum range.

The need for radio relay did not really begin until the 1940s exploitation of microwaves, which traveled by line of sight and so were limited to a propagation distance of about 40 miles by the visual horizon.

Military microwave relay systems continued to be used into the 1960s, when many of these systems were supplanted with tropospheric scatter or communication satellite systems.

Long-distance microwave relay networks were built in many countries until the 1980s, when the technology lost its share of fixed operation to newer technologies such as fiber-optic cable and communication satellites, which offer a lower cost per bit.

At the turn of the century, microwave radio relay systems are being used increasingly in portable radio applications.

Microwave relay link is a communications system that uses a beam of radio waves in the microwave frequency range to transmit video, audio, or data between two locations, which can be from just a few feet or meters to several miles or kilometers apart.

Microwave relay links are commonly used by television broadcasters to transmit programmes across a country, for instance, or from an outside broadcast back to a studio.

Terrestrial microwave relay links are limited in distance to the visual horizon, a few tens of miles or kilometers depending on tower height.
