høyfrekvensområder
Høyfrekvensområder, also known as high-frequency bands, refer to the range of electromagnetic frequencies that are higher than those used for standard radio broadcasting. These frequencies typically range from 30 MHz to 300 GHz, according to the International Telecommunication Union's (ITU) radio frequency allocation chart. The high-frequency bands are further divided into several sub-bands, each with its own specific applications and characteristics.
The use of high-frequency bands is crucial for various modern technologies. For instance, the 2.4 GHz and
The propagation characteristics of high-frequency bands differ from those of lower frequencies. Due to their shorter
The allocation and regulation of high-frequency bands are managed by national and international regulatory bodies to
