what are the aviation frequencies?
531979
Airband radios use VHF frequencies and channels, different to those channels that are used on the ground as they are specifically set aside for use in avionics environments. Typically between 108 and 137 MHz. Airband radios are divided into COM for voice communication and NAV for navigation.

The lowest frequency portion of the electromagnetic spectrum is designated as “radio,” generally considered to have wavelengths within 1 millimeter to 100 kilometers or frequencies within 300 GHz to 3 kHz. There is a wide range of subcategories contained within radio including AM and FM radio.

What frequency does 5G use? High-band spectrum is sometimes called millimeter wavelength (mmWave) in the cellular industry, and it enables about 28 GHz of frequency. This is considerably faster than 4G networks, which use about 700 MHz-2500 MHz frequency to transfer information.

According to US frequency groups there are four different categories: low-band VHF (49-108 MHz), high-band VHF (169-216 MHz), low-band UHF (450-806 MHz), and high-band UHF (900-952 MHz). The FCC is in control of who operates within each specific band and if anyone has priority over other operators.

Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies as high as 300 gigahertz (GHz) to as low as 30 hertz (Hz). At 300 GHz, the corresponding wavelength is 1 mm, and at 30 Hz is 10,000 km.

400 Hz. Power frequencies as high as 400 Hz are used in aircraft, spacecraft, submarines, server rooms for computer power, military equipment, and hand-held machine tools.

Radio waves are at the lowest range of the EM spectrum, with frequencies of up to about 30 billion hertz, or 30 gigahertz (GHz), and wavelengths greater than about 10 millimeters (0.4 inches). Radio is used primarily for communications including voice, data and entertainment media.
1064124
The terahertz, abbreviated THz, is a unit of electromagnetic (EM) wave frequency equal to one trillion hertz (1012 Hz). The terahertz is used as an indicator of the frequency of infrared (IR), visible, and ultraviolet (UV) radiation.
742019
The lowest frequencies (longest wavelengths) constitute the radio spectrum. Parts of the radio spectrum are used for radar and passive detection. Above the radio-frequency spectrum lies the infrared spectrum, followed by the visible range, which is quite narrow.

In the 2013 spectrum auction, the Government planned to auction 50 MHz of airwaves in the 1800 MHz band and 76.25 MHz of spectrum in the 800 MHz band. ... No companies tendered bids for spectrum in 1800 MHz and 900 MHz bands, and MTS India was the only bidder in the 800 MHz band.

The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.
1068980
The frequencies of radar sets today range from about 5 megahertz to about 130 gigahertz (130,000,000,000 oscillations per second!). However, certain frequencies are also preferred for certain radar applications. Very long-range radar systems usually operate at lower frequencies below and including the D-band.
