Taajuusryhmiä

Taajuusryhmiä, or frequency bands, are specific ranges of electromagnetic frequencies used for various purposes in communication, broadcasting, and other technologies. These bands are regulated by international bodies such as the International Telecommunication Union (ITU) to prevent interference and ensure efficient use of the electromagnetic spectrum. Each band is allocated for specific types of services, such as radio broadcasting, television, mobile communications, satellite communications, and more.

The International Telecommunication Union (ITU) divides the electromagnetic spectrum into several frequency bands, each with its own characteristics and applications. For example, the Very Low Frequency (VLF) band, ranging from 3 kHz to 30 kHz, is used for long-range navigation and communication, while the Ultra High Frequency (UHF) band, ranging from 300 MHz to 3 GHz, is used for television broadcasting and mobile communications.

The allocation of frequency bands is crucial for the functioning of modern communication systems. It ensures that different services do not interfere with each other, allowing for efficient and reliable communication. The ITU regularly reviews and updates these allocations to accommodate new technologies and services.

In summary, taajuusryhmiä, or frequency bands, are essential for the operation of various communication and broadcasting technologies. They are regulated by international bodies to prevent interference and ensure efficient use of the electromagnetic spectrum. Each band is allocated for specific types of services, ranging from long-range navigation to mobile communications.
