What Is C Ku Band Satellite

The band in use refers to the radio frequencies used to and from the satellite.

What is c ku band satellite.

Circular polarization cp in turn is of two types right hand and left hand. 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. Frequencies between 10 700 12 750 ghz are on ku band. It is one of the major technologies used today for high speed satellite internet.

The ka band k band above is primarily used for two way consumer broadband and military networks. Ku band is under that in the frequency of 12 18 ghz. Because of the higher frequencies ku band waves have shorter wavelengths. Ku band frequencies or signals are mostly used for satellite communication like dth direct to home live feed.

This is because the license fees for c band bandwidth are cheaper than ku band less operational expenditure opex. Frequencies between 3 700 4 200 ghz are on c band and require a satellite dish 7 5 2 25m or larger. From a commercial point of view c band is better for satellite applications that need larger bandwidth. What is c band ku band.

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. K u band is primarily used for satellite communications most notably the downlink used by direct broadcast satellites to broadcast satellite television and for specific applications such as nasa s tracking data relay satellite used for international space station iss communications and spacex starlink satellites. Ka band dishes can be much smaller and typically range from 60cm 1 2m 2 to 4 in diameter. 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.

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. 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.
