Partsávok

Partsávok, also known as frequency bands or radio bands, are specific ranges of radio frequencies allocated for particular purposes. These bands are crucial for the orderly operation of wireless communication technologies, ensuring that different services do not interfere with each other. The allocation and management of these partsávok are overseen by international bodies like the International Telecommunication Union (ITU) and national regulatory authorities.

Each partsáv is defined by a lower and upper frequency limit. For instance, the AM broadcast band is a partsáv, as is the FM broadcast band, the cellular phone bands, Wi-Fi frequencies, and satellite communication bands. Different partsávok have distinct characteristics regarding propagation, bandwidth, and the amount of data they can carry. Lower frequencies tend to travel further and penetrate obstacles better, while higher frequencies can accommodate larger amounts of data but have a shorter range and are more easily blocked.

The allocation of partsávok is a complex process that balances the needs of various services, including broadcasting, mobile communications, navigation, scientific research, and emergency services. Regulations dictate which partsávok can be used by whom and for what purpose, often involving licensing to manage access and prevent interference. The efficient use of partsávok is essential for the growth and innovation in wireless technologies. As new technologies emerge, such as 5G and beyond, the allocation and re-allocation of partsávok become increasingly important to accommodate demand.
