What is the radio frequency range?

The radio frequency (RF) range is a portion of the electromagnetic spectrum that falls between 3 kilohertz (kHz) and 300 gigahertz (GHz). It includes frequencies used for radio communication, such as AM and FM radio, as well as for other purposes, such as wireless communication, radar, and navigation systems.

The RF range is commonly divided into several bands based on their frequency ranges:

* Very low frequency (VLF): 3 kHz to 30 kHz

* Low frequency (LF): 30 kHz to 300 kHz

* Medium frequency (MF): 300 kHz to 3 MHz

* High frequency (HF): 3 MHz to 30 MHz

* Very high frequency (VHF): 30 MHz to 300 MHz

* Ultra high frequency (UHF): 300 MHz to 3 GHz

* Super high frequency (SHF): 3 GHz to 30 GHz

* Extremely high frequency (EHF): 30 GHz to 300 GHz

The RF range is widely used for various applications, including:

* Radio communication: AM and FM radio broadcasting, mobile phones, wireless devices, and walkie-talkies.

* Navigation: GPS (Global Positioning System) navigation and satellite navigation systems.

* Remote control: Garage door openers, keyless entry systems, and other remote control devices.

* Industrial and scientific: Microwave ovens, radar systems, medical imaging, and industrial heating.

* Space communication: Satellite communication and deep-space exploration.

Each frequency band within the RF range has its own characteristics and is used for specific purposes based on its propagation properties, range, and bandwidth requirements.
