kõrgsagedusvahemikud

Kõrgsagedusvahemikud, also known as frequency bands, are specific ranges of electromagnetic frequencies used for various communication and data transmission purposes. These bands are regulated by international bodies such as the International Telecommunication Union (ITU) to ensure efficient and non-interfering use of the electromagnetic spectrum. Each band is allocated for specific applications, such as radio broadcasting, mobile communications, satellite communications, and more.

The allocation of frequency bands is crucial for preventing interference between different services. For example, the Very High Frequency (VHF) band, which ranges from 30 MHz to 300 MHz, is primarily used for television broadcasting and two-way radio communications. The Ultra High Frequency (UHF) band, ranging from 300 MHz to 3 GHz, is used for television broadcasting, mobile communications, and wireless LANs.

The allocation of frequency bands is subject to change as technology advances and new applications emerge. For instance, the increasing demand for mobile data has led to the reallocation of certain bands to accommodate 5G networks. The management of frequency bands is a complex task that requires coordination among governments, regulatory bodies, and industry stakeholders to ensure optimal use of the electromagnetic spectrum.
