C Band Satellite Frequencies

The benefit of c band compared to mmwave can be assessed from two different viewpoints.

C band satellite frequencies.

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

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. Because of its weaker power it requires a larger antenna usually above 1 8m 6ft. Used mostly for commercial satellite television transmissions c band is becoming less of a residential option. 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.

C band covers from 3 7 to 8 ghz however the frequency range for satellite television is from 3 7 to 4 2 ghz. 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. C band satellite systems use a 6 to 12 foot dish for reception of television and data transmissions.

C band 4 8 ghz primarily used for satellite communications for full time satellite tv networks or raw satellite feeds. 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.
