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
