Why is Radio Frequency used in mobile communication?
the frequency used in mobile communication should be greater then 30mhz so cannot be reflected by the ionosphere thats why we are using a frequency of range less ghz so called "radio waves"
What was the first ever mobile phone invented?
Wasnt a phone as such, first wireless communication was through Morse code using long range frequency devices. Very primative now but still effective if you know how.
What is a lock in range and a capture range?
Lock range is the input frequency range of the PLL over which out frequency changes in step with input frequency, where as capture range is the frequency range over which oput starts to responds to input frequency change.
What is the frequency range for radio wave?
We generate and detect radio waves for purposes of communication, cooking, andscientific investigation, in the frequency range of roughly 30 KHz to 300 GHz,corresponding to wavelengths between 10,000 meters and 1 millimeter.
What is the frequency range used in wireless communication?
2.4GHz is used & OFDM
What is the frequency range on an OE-254?
What is the frequency range of an OE
How satellite communication is different from communication relay?
For communication satellites the range is much higher than that of communication relay. Communication Satellite can cover up to several thousands of kilometers. For communication relay, the uplink and the downlink frequency is the same. But for communication satellites the uplink and the downlink frequencies are different in order to avoid interference.
What is the operating frequency of optical fiber?
In Optical Fiber Communication system 1300-1550 nm range wavelengths are used.. Reason for tis s "In this range only we can acheive low attenuation with zero dispersion"
What is Broadcasting signal frequency range?
The broadcasting frequency range is from 300kHZ to 3400kHZ.
What is the Frequency range for EL frequency?
315mhz
What is the frequency of a police radio?
Basically it is a push to talk service.Where one can talk only(transmitter) and other are listen(receiver).When any one push the button then he only can talk.The range of this type of communication is 200-500 meter.Frequency range is 400-2700MHz. Frequency Range (UHF): - Channel 1, 400-420MHz - Channel 2, 430-450MHz ... Communication Range: 5KM+ .Push-to-talk cellular calls are half-duplex communications .Written by Kapil Sadhu.
Frequency modulation range in India?
The frequency range of FM signal is 88hz to 108hz.
