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 is the color subcarrier frequency?
A modulated monochrome signal whose side-bands convey color information.
What type of electromagnetic wave is used for radar?
It is microwaves that are used for radar. They are high frequency, short wavelength electromagnetic waves, and a number of different frequency ranges of these microwaves are used depending on the application. A link is provided to the Wikipedia article on radar and the different bands or ranges of frequencies that are used and their applications.
What are resistance bands used for?
Resistance bands are used to strain people's muscles, thus strengthening their bodies. Using resistance bands correctly one can replace a whole gym with resistance bands.
Are rubber bands made out of rubber?
Yes, rubber bands are made out of rubber.(:
Why must a satellite have a distinct up link and down link frequencies?
These are frequencies used for satellite communications. Usually in the Gigahertz bands. Uplink is on a differenct channel to downlink, to avoid interferece. The Uplink, is the signal sent to the satellite, via a dish antenna, which focuses the signal in the direction of the satellite. On board the satellite, this signal is changed and re-transmitted, on a different frequency (Downlink), and beamed back to earth. This way huge distances can be covered on earth, despite the curvature and with minimal power.
Which has a higher frequency infrared or TV?
Infrared radiation is much higher frequency (300 GHz to 430 THz) than the VHF and UHF bands (30 MHz to 3 GHz) frequencies used by broadcast TV.
What are the two main bands of television wave frequencies?
Amplitude and frequency
What are two main bands of television wave frequencies?
Amplitude and frequency
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
What is the limitation of radio waves?
Radio is limited by its own design. AM & FM bands are frequency transmitted as radio waves. However since earth is round waves travels directly they do not bend. So as a rule the higher the frequency the more direct they are FM frequency is considered as line of sight transmission AM will have more range since it operates at lower frequency. At very low frequency it is possible to transmit around the earth by using the ionosphere curvature
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 do infrared and radio waves have in common?
They are just different frequency bands of the electromagnetic spectrum.
Why arn't solgers and bands allowed to march over bridges?
Soldiers and bands break step so as not to reinforce the fundamental vibration frequency of the bridge. For an example of wind reinforceing the fundamental frequency look up the Tacoma Narrows Bridge.
Why do uhf and vhf relate to television broadcasts?
Early television broadcasts were transmitted on VHF (very high frequency) radio channels. They moved to UHF (ultra high frequency) and have remained on that band since. These bands are used for terrestrial broadcasts. Satellite broadcasts use even higher frequencies.
Frequency of radio wave for RFID tags?
Depends on where you are. Each nation has its own rules. There are legal frequencies in the 125 KHz, 13.56 MHz, 800-950 MHz, and 2.4 MHz bands. Higher frequencies are coming.
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 3 forms of Electromagnetic Radiation with a wavelength less than visible light?
The wavelength of electromagnetic radiation is a measure of the frequency; multiply the frequency times the wavelength, and the answer is ALWAYS the "Speed of Light", which we abbreviate as "c". All of these are different "bands" of electromagnetic energy. Radio is the longest wavelength and lowest frequency. "Low Frequency" is the lowest, followed by "high frequency", "very high frequency" or VHF, "ultra-high frequency" or UHF. Beyond that are microwaves, and then heat, then "infrared", and then visible light. Higher frequency (and shorter wavelengths) than light are "ultra-violet", then X-rays, and then "gamma rays".
