Mikroaaltoliikenne

Mikroaaltoliikenne refers to the transmission of information using microwave frequencies. These electromagnetic waves, typically ranging from 1 to 300 gigahertz, have wavelengths between one meter and one millimeter. Due to their properties, microwaves can travel long distances in a straight line and are highly directional, making them suitable for point-to-point communication.

The technology plays a crucial role in various communication systems. Microwave links are commonly used for long-distance telephone calls, television broadcasting, and data transmission, especially in areas where laying cables is impractical or too expensive. Satellite communication heavily relies on microwave frequencies to relay signals between ground stations and orbiting satellites.

Another significant application is in radar systems. Radar uses microwave pulses to detect objects, measure their distance, speed, and direction. This technology is vital for air traffic control, weather forecasting, and military surveillance. Microwave ovens also utilize microwave radiation, specifically at a frequency of 2.45 gigahertz, to heat food by causing water molecules to vibrate.

The development of microwave technology has been instrumental in the evolution of modern telecommunications and sensing technologies, enabling faster and more efficient ways to transmit information and perceive the environment.
