The military typically uses several frequency bands for various communication, radar, and navigation purposes. These bands can be broadly categorized into low frequency (LF), high frequency (HF), very high frequency (VHF), ultra high frequency (UHF), super high frequency (SHF), and extremely high frequency (EHF). Each band serves different operational needs, with some dedicated to secure communications, while others are used for surveillance and targeting. The exact number of frequency bands may vary based on specific military applications and technology advancements.
What else can I help you with?
Why do the cell-phones use higher frequency bands Ghz and not lower ones Khz-Mhz?
The lower bands are already in use, and have been for many years. Additionally, the higher frequencies allow the use of very small antennas and some other components that reduce the size of the phones. Microcircuits for microwaves.
How do you convert low frequency to high frequency with a circuit?
You typically create a DC power supply from the low frequency, and use that to run a high frequency oscillator and amplifier. If there needs to be a relationship between frequency in and frequency out, often there is a divider running on the high frequency side in combination with a phase locked loop synching up to the low frequency side.
What is the wavelength for 835.6 MHz?

Use the relationship: speed = frequency x wavelength.You didn't specify what kind of wave. Use the relationship: speed = frequency x wavelength.You didn't specify what kind of wave. Use the relationship: speed = frequency x wavelength.
How do you adjust frequency on VFD?
To adjust the frequency on a Variable Frequency Drive (VFD), you typically access the control panel or interface of the VFD. From there, you can either manually input the desired frequency value or use programmable settings to change the frequency based on specific operational needs. Additionally, many VFDs allow for remote control adjustments via external controls or communication protocols. Always refer to the manufacturer's manual for detailed instructions specific to your VFD model.
What does multiplexing use to prevent channel frequencies from overlapping?
Guard bands between channels
What frequency do police radios use?
While there are several radio bands in use by law enforcement, there is no one channel or frequency that all use.
What is the saxophone of made and used for?
Military marching bands, concert bands, high school marching bands, and college marching bands use saxophones for their music. It is a flexible-use instrument.
What frequency is free?
The frequency bands set aside for unlicensed use, often referred to as "free frequency," include the 2.4 GHz and 5 GHz bands commonly used for Wi-Fi and Bluetooth devices. These bands are open for usage without requiring a license from regulatory authorities in most countries.
What are the different wireless mic frequency bands available for use in audio applications?
The different wireless mic frequency bands available for use in audio applications are VHF (Very High Frequency), UHF (Ultra High Frequency), and 2.4 GHz. Each band has its own advantages and considerations for optimal performance in different environments.
What is meant by WARC in Amateur Radio use?
WARC stands for World Administrative Radio Conference which is organised by the International Telecommunications Union. The conference sets up international agreements on the use of radio frequency bands. One advantage of the 1979 conference was the allocation of new frequency bands for amateur radio use on HF. These bands are 30m, 17m & 12m and are generally referred to as the WARC bands.
What are the different wireless microphone frequency bands available for use?
The different wireless microphone frequency bands available for use are VHF (Very High Frequency), UHF (Ultra High Frequency), and 2.4 GHz. Each band has its own advantages and limitations, so it's important to choose the right one based on your specific needs and environment.
How is interference avoided by using FDM?
Interference is avoided under frequency division multiplexing by the use of guard bands, which are unused portions of the frequency spectrum between subchannels. by abdullahi yusuf gedi
Where is the trombone mainly used?
In the first times of its creation the trombone was originally used in town bands but later it developed into use in military bands. In the 1920s it was used in jazz bands.
Why do the cell-phones use higher frequency bands Ghz and not lower ones Khz-Mhz?
The lower bands are already in use, and have been for many years. Additionally, the higher frequencies allow the use of very small antennas and some other components that reduce the size of the phones. Microcircuits for microwaves.
What frequency does GPS use for its signal transmission?
GPS uses radio frequency signals in the L1 (1575.42 MHz) and L2 (1227.60 MHz) bands for its signal transmission.
Which is the network has the more users in Sri Lanka?
What frequency bands are allocated in sri lanka for use by the mobile telephone network?
What are the different wireless microphone bands available for use in live performances?
The different wireless microphone bands available for use in live performances are VHF (Very High Frequency), UHF (Ultra High Frequency), and 2.4 GHz. Each band has its own advantages and limitations in terms of range, interference, and signal quality.
