Rádiótartományba

Rádiótartományba refers to the radio frequency spectrum, a range of electromagnetic radiation with wavelengths from about one millimeter to 100 kilometers. This corresponds to frequencies between 300 gigahertz and 3 kilohertz. The radio spectrum is a finite natural resource and is divided into different bands, each with specific properties and applications. These bands are regulated internationally by the International Telecommunication Union (ITU) and nationally by government agencies.

Different parts of the radio spectrum are used for a vast array of technologies and services. Lower frequency bands, for instance, are good for long-distance communication due to their ability to diffract around obstacles and penetrate the ionosphere. These are used for broadcasting radio and television, amateur radio, and maritime communications. Higher frequency bands have shorter wavelengths and can carry more information, making them suitable for mobile phone communications, Wi-Fi, radar, satellite communications, and radio astronomy. The efficient allocation and management of the radio spectrum are crucial for modern society, enabling everything from global communication networks to scientific research. Interference between different services is a significant concern, leading to strict regulations and spectrum management practices.
