A microwave link is a communications system that uses a beam of radio waves in the microwave frequency range to transmit information between two fixed locations on the earth. They are crucial to many forms of communication and impact a broad range of industries. Government agencies use them to provide communications networks between nearby facilities within an organization, such as a company with several buildings within a city.
One of the reasons microwave links are so adaptable is that they are broadband and their cost is fixed, not recurring like fiber. That means they can move large amounts of information at high speeds at a very low comparable cost. Another important quality of microwave links is that they require no equipment or facilities between the two terminal points, so installing a microwave link is often faster and less costly than a cable connection. Finally, they can be used almost anywhere, as long as the distance to be spanned is within the operating range of the equipment and there is clear path (that is, no solid obstacles) between the locations. Microwaves are also able to penetrate rain, fog, and snow, which means bad weather doesn’t disrupt transmission.
