C Band Satellite Frequencies

Note that by using the band from 3 7 to 4 0 ghz this c band overlaps somewhat into the ieee s band for radars.

C band satellite frequencies.

Part of this spectrum is known as c band. The c band is primarily used for voice and data communications as well as backhauling. Most importantly the us federal communications commission fcc is scheduled to vote tomorrow on making 280 mhz of spectrum from what s called c band 3 7 4 2 ghz available for auction. Because of its weaker power it requires a larger antenna usually above 1 8m 6ft.

C band covers from 3 7 to 8 ghz however the frequency range for satellite television is from 3 7 to 4 2 ghz. Commonly used in areas that are subject to tropical rainfall since it is less susceptible to rainfade than ku band the original telstar satellite had a transponder operating in this band used to relay the first live transatlantic tv signal in 1962. Ku band satellite will have 14 to 14 5 ghz range in the uplink and 11 7 to 12 2 ghz frequency range in the downlink. C band sits between 3 4 ghz and 4 2 ghz and is emerging as a prime resource for the capacity crunch without incurring high cost investments that would otherwise be required to upgrade the infrastructure.

C band 4 8 ghz primarily used for satellite communications for full time satellite tv networks or raw satellite feeds. Pai said on monday. However due to the lower frequency range it performs better under adverse weather conditions on the ground. Nearly all c band communication satellites use the band of frequencies from 3 7 to 4 2 ghz for their downlinks and the band of frequencies from 5 925 to 6 425 ghz for their uplinks.

C band satellite systems use a 6 to 12 foot dish for reception of television and data transmissions. The benefit of c band compared to mmwave can be assessed from two different viewpoints.
