Explanation: 

Detailed explanation-1: -A microwave 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.

Detailed explanation-2: -Microwave radio transmission is commonly used in point-to-point communication systems on the surface of the Earth, in satellite communications, and in deep space radio communications. Other parts of the microwave radio band are used for radars, radio navigation systems, sensor systems, and radio astronomy.

Detailed explanation-3: -The two types of microwave transmission are terrestrial and satellite: Terrestrial microwave transmissions are sent between two microwave stations on the earth (earth station). It is the most common form of long-distance communication.

Detailed explanation-4: -A line-of-sight microwave link uses highly directional transmitter and receiver antennas to communicate via a narrowly focused radio beam. The transmission path of a line-of-sight microwave link can be established between two land-based antennas, between a land-based antenna and a satellite-based antenna, …
