What Is C Ku Band Satellite
What is c band ku band.
What is c ku band satellite. Frequencies between 10 700 12 750 ghz are on ku band. Ku band frequencies or signals are mostly used for satellite communication like dth direct to home live feed. Shorter wavelengths mean that you need a smaller dish to receive these frequencies. Transmission power is much greater compared to the c x or ku band beams.
The c band 4 to 8 ghz is used for many satellite communications transmissions some wi fi devices some cordless telephones as well as some surveillance and weather radar systems contents 1 use in satellite communication. Frequencies between 3 700 4 200 ghz are on c band and require a satellite dish 7 5 2 25m or larger. Ka band dishes can be much smaller and typically range from 60cm 1 2m 2 to 4 in diameter. The ku band frequency range is 11 7 12 2 ghz or 11700 to 12220 mhz notice how these frequencies are higher than the c band frequency range.
Ku band a portion of the electromagnetic spectrum is the lower part of 3 bands of the original nato k band an obsolete designation given to radio frequencies ranging from 20 40 gigahertz ghz. From a commercial point of view c band is better for satellite applications that need larger bandwidth. This is because the license fees for c band bandwidth are cheaper than ku band less operational expenditure opex. Circular polarization cp in turn is of two types right hand and left hand.
Because of the higher frequencies ku band waves have shorter wavelengths. Ku band is under that in the frequency of 12 18 ghz. The band in use refers to the radio frequencies used to and from the satellite. For instance due to dual polarization the 500 mhz raw spectrum allocated to fixed satellite services fss in either c band or ku band is reused to make it into 1 ghz spectrum.
It is one of the major technologies used today for high speed satellite internet. C band and ku band fall under microwave frequencies and correspond to different regions within the electromagnetic spectrum as can be seen from the given below figure. L band uses frequencies in the 1 to 2ghz range ku band utilises approximately 12 18ghz and ka band services uses the 26 5 40ghz segment of the electromagnetic spectrum.
