UHF stands for Ultra high frequency.
The term UHF is an acronym used in the field of radio communications to denote a specific range of radio frequencies.
As defined by the International Telecommunication Union (ITU), UHF stands for Ultra high frequency.
This designation covers radio frequencies found in the range between 300 megahertz (MHz) and 3 gigahertz (GHz). This band of frequencies is also commonly known as the decimetre band because the corresponding wavelengths range from one meter down to one tenth of a meter (which is one decimeter).
Here's a simple breakdown:
| Acronym | Stands For | Frequency Range | Wavelength Band |
|---|---|---|---|
| UHF | Ultra high frequency | 300 MHz to 3 GHz | Decimetre Band |
Frequencies in the UHF range are utilized for a wide variety of modern communication applications, including:
- Television broadcasting (though this varies by region)
- Mobile phone networks
- Wi-Fi and Bluetooth technology
- GPS systems
- Two-way radio communication (like walkie-talkies)
These frequencies are favoured for many short to medium-range communications due to their ability to carry significant amounts of data and penetrate buildings more effectively than higher frequencies, although they are more easily blocked by obstacles than lower frequencies.
