What Is C Ku Band Satellite

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.

What is c ku band satellite.

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. C band is preferred in some locations where rainfalls are heavy as the situation in tropical regions of africa. What is c band ku band. 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.

It is one of the major technologies used today for high speed satellite internet. 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.

From a commercial point of view c band is better for satellite applications that need larger bandwidth. Circular polarization cp in turn is of two types right hand and left hand. Frequencies between 3 700 4 200 ghz are on c band and require a satellite dish 7 5 2 25m or larger. 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. 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. This is because the license fees for c band bandwidth are cheaper than ku band less operational expenditure opex. Frequencies between 10 700 12 750 ghz are on ku band.

The ka band k band above is primarily used for two way consumer broadband and military networks. 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. Ka band dishes can be much smaller and typically range from 60cm 1 2m 2 to 4 in diameter.
