- Microwave transmission is the transmission of information or energy by electromagnetic waves whose wavelengths are measured in small numbers of centimeter; these are called microwaves. Microwave signals are similar to radio and television signals and are used to transmit data through the space without the use of cable.
- Microwave signals cannot bend or pass obstacles like hill. So the transmitter and receiver or a a microwave transmission, which are mounted on very high towers, should be in a line of sight.
- Microwaves are widely used for point-to-point communications because their small wavelength allows conveniently-sized antennas to direct them in narrow beams, which can be pointed directly at the receiving antenna.
