What Is C Ku Band Satellite

This is because the license fees for c band bandwidth are cheaper than ku band less operational expenditure opex.

What is c ku band satellite.

Shorter wavelengths mean that you need a smaller dish to receive these frequencies. What is c band ku band. Ku band frequencies or signals are mostly used for satellite communication like dth direct to home live feed. The ka band k band above is primarily used for two way consumer broadband and military networks.

Ka band dishes can be much smaller and typically range from 60cm 1 2m 2 to 4 in diameter. It is one of the major technologies used today for high speed satellite internet. 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. 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.

The band in use refers to the radio frequencies used to and from the satellite. From a commercial point of view c band is better for satellite applications that need larger bandwidth. 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. 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.

Because of the higher frequencies ku band waves have shorter wavelengths. Ku band is under that in the frequency of 12 18 ghz. Transmission power is much greater compared to the c x or ku band beams. 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. C band is preferred in some locations where rainfalls are heavy as the situation in tropical regions of africa. Frequencies between 10 700 12 750 ghz are on ku band.
