2.4GHz microwave, a band assigned for low power unlicensed users (including microwave cookers) that must tolerate interference from any other user of the band, even if the interference makes them inoperative.
I think g is also allowed on 4.8GHz microwave.
RF=Radio Frequency, a wave that is used to send data wirelessly
AM (amplified modulation) radio contain the intermediate frequency transformer.it has IF to mixed the carrier signal into local oscillator signal in a process called heterodyning, resulting in a signal at the difference or beat frequency. Intermediate frequency are used in superheterodyne radio recievers, in which an incoming signals is shifted to an IF for amplication before final destination is done.
FM means Frequency Modulated.FM stands for modulation on frequency or frequency modulation.
A radio programme receiver does not need to be directly in view of the transmitter to receive programme signals. For low frequency radio waves diffraction can allow them to be received behind hills, although repeater stations are often used to improve the quality of the signals.
"Microwave" is the loose term used to describe the higher-frequency portion of the general category of radio waves. The closest thing to a formal definition says that "microwave" is anything with a frequency higher than 3 GHz (wavelength less than 10 centimeters).
radio frequency for link to bts to bscs/msc
95 GHz
Frequency
Frequency modulation is used to broadcast radio waves to receivers. The most common use of it is in FM radio, which contains a range of radio frequencies.
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"
The term often used to describe interference of radio waves is "radio frequency interference" (RFI). RFI can disrupt the normal operation of electronic devices that rely on radio frequency signals for communication.
What is sometimes called a Radio Frequency lead is a shielded cable used beween pieces of equipement to reduce the effects of radio frequency interference.
The part that we call "Extremely Low Frequency Radio Waves".
Very Low Frequency radio signals.
14 megahertz
This piece of equipment is used to convert a frequency from one channel to another. This is used in radio operations.
In round figures 1 Km (AM broadcast radio) to 0.1 mm (microwave).
