What is ultra-high frequency(UHF)?
The band of electromagnetic radiation with a radio frequency range of 300 MHz to 3 GHz is known as ultra-high frequency(UHF). With a wavelength ranging from 1 to 1 dm, this band is also referred to as the decimeter band. UHF radiation is less impacted by environmental conditions, they are more frequently utilised for channel broadcasting and TV and radio transmission. They have high directivity, but the receiving error also rises at the same time.
UHF radio uses a wide variety of frequencies:
- 450 MHz: Commercial radio services, such as land mobile radio systems used by transportation corporations.
- 470-512 MHz: Public safety radio services, like communications between the police and fire. Department :
- 800 MHz: Public safety radio services and mobile phone communication both use the 800 MHz frequency.
- 90 MHz: This frequency is utilised for business and industrial purposes, including wireless data transfer.
