C Band Satellite Frequencies

The c band is primarily used for voice and data communications as well as backhauling.

C band satellite frequencies.

However due to the lower frequency range it performs better under adverse weather conditions on the ground. 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. 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.

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. 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 satellite will usually will have 5 925 to 6 425 ghz frequency range in the uplink and 3 7 to 4 2 ghz frequency range in the downlink. Part of this spectrum is known as c band.

C band covers from 3 7 to 8 ghz however the frequency range for satellite television is from 3 7 to 4 2 ghz. C band 4 8 ghz primarily used for satellite communications for full time satellite tv networks or raw satellite feeds. 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. The so called c band spectrum which includes 500 mhz of spectrum between 3 7 and 4 2 ghz is used today by satellite providers to deliver video programming to cable providers.

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. 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.
