Microwave GHz bands are owned and regulated by national governments and their respective telecommunications authorities. In the U.S., the Federal Communications Commission (FCC) manages these frequencies, while in other countries, similar regulatory bodies oversee the allocation and licensing. Typically, these bands are allocated for various uses, including commercial telecommunications, broadcasting, and scientific research, and can be leased or licensed to private companies. Ownership can vary based on specific frequency ranges and intended applications.
The formal definition of "microwave" is any frequency greater than 3 GHz. (Wavelength less than 10 centimeters.) Frequency bands allocated for microwave radio communication in the US are found in the neighborhoods of 6, 11, 13, 18, 23, 24, 27, and 38 GHz. Note: It looks like the the formal definition of "microwave" doesn't include microwave ovens ... they operate at 2.45 GHz.
3 GHZ TO 30 GHZ
The wavelength of a microwave at 2.30 GHz is approximately 130 millimeters (mm), which is equivalent to 130,000 nanometers (nm).
Microwaves are radio waves.Technically, "microwave" is the term used to designate radio communication onfrequencies above 3 GHz. Cellular and mobile data service doesn't operate inthat frequency range. But microwave systems operating in bands between5.8 GHz and 80 GHz are used to link the individual cellular and mobile data sitesto each other, and to the mobile switching centers.
Microwave is a radio wave.Depending on the country you're operating in and the standard to whichyour Wi-fi equipment operates, you'll be conducting radio communicationaround 2.4 GHz, or 3.6 GHz, or 4.9 to 5.8 GHz.(If you want to be super-technical about it, microwaves are radio waves withfrequencies above 3.0 GHz. This leads to the awkward fact that microwave ovens,operating around 2.46 GHz in the US, don't literally use microwave radiation.)
"Microwave" radiation is any radio wave at frequencies between 3 GHz and 300 GHz. Microwave cooking ovens are licensed to operate at a certain definite frequency, just like any other radio transmitter is. For microwave ovens in the US, the frequency is 2.450 GHz.
The frequency range of a microwave oven is typically around 2.45 gigahertz (GHz).
The microwave region is a set of electromagnetic frequencies, at a higher freqency than radio waves but lower than terahertz radiation and infrared radiation.==============================Answer #2:3 GHz to 300 GHz
to produce freq in the range of ghz tat is microwave freq range
It is radio waves, at the frequency of 2.45 GHz, and very high power.
Microwave ovens use electromagnetic radiation in the microwave region of the electromagnetic spectrum. Specifically, they typically operate at a frequency of 2.45 GHz, which corresponds to a wavelength of around 12 cm.
BTS are usually linked to MSC by fiber whenever that's feasible. If fiber is unavailable or too expensive, the "backhaul" network consists of high-capacity, short distance, low power digital microwave links. In the US, the popular frequencies for this application are the licensed bands in 11, 18, 23, and 38 GHz, as well as the unlicensed bands in 5.9, 28, and 80 GHz.
