point-to-point microwave transmission
Quick Summary
Point-to-point microwave transmission uses directional antennas to send a focused radio beam between two locations. This method is employed for various communication needs, including military operations, television feeds, and inter-urban telephone traffic.1
These links operate at frequencies between 1 and 25 gigahertz, allowing for high transmission bandwidths. The maximum range for land-based systems is limited by the Earth's curvature, necessitating repeaters on towers spaced about 50 km apart. Atmospheric conditions can affect the signal, causing fading or even complete loss of the beam if not properly managed. Microwave transmission offers an advantage as it doesn't require continuous land access along the entire path, unlike some other methods.12

First employed in 1950, microwave transmission has the advantage of not requiring access to all contiguous land along the path of the system. Because microwave systems are line-of-sight media, radio towers must be spaced approximately every 42 km (25 miles) along the…
