What Is C Ku Band 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.

What is c ku band satellite.

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 band in use refers to the radio frequencies used to and from the satellite. 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. 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. Transmission power is much greater compared to the c x or ku band beams. From a commercial point of view c band is better for satellite applications that need larger bandwidth.

Because of the higher frequencies ku band waves have shorter wavelengths. Circular polarization cp in turn is of two types right hand and left hand. 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. 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.

Ka band dishes can be much smaller and typically range from 60cm 1 2m 2 to 4 in diameter. 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. Ku band is under that in the frequency of 12 18 ghz. 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.

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. The ka band k band above is primarily used for two way consumer broadband and military networks.
