Frequency Bands Used For Satellite Communication

The higher frequency bands typically give access to wider bandwidths but are also more susceptible to signal degradation due to rain fade the absorption of radio signals by atmospheric rain snow or ice.

Frequency bands used for satellite communication.

Frequency bands used in satellite communication. The russians have often used the hf bands at 21 and 29 mhz for amateur communications. Very high frequency vhf very high frequency is one of the most commonly used bands which has an operating range from 30 mhz to 300 mhz. The other amateur radio oscar satellites operate in vhf uhf range.

High frequency band is mostly used by aviation industry near field communication nfc government systems amateur radio operators and weather broadcasting stations. X band satellite communication operates in the part of the x band or super high frequency shf spectrum which is designated by the international telecommunication union itu for satellite communication which is those frequencies in the range 7 25 ghz to 7 75 ghz space to earth and 7 9 ghz to 8 4 ghz earth to space. With the variety of satellite frequency bands that can be used designations have been developed so that they can be referred to easily. The communications c band was the first frequency band that was allocated for commercial telecommunications via satellites.

There are a number of radio frequency ranges in use in satellite communications such as c x ku ka and even ehg and v band. Posted on march 9 2009. The same frequencies were already in use for terrestrial microwave radio relay chains. S band 2 4 ghz weather radar surface ship radar an.

C band 4 8 ghz ku band 10 18 ghz ka band 18 31 ghz some satellite systems use c band and thus employ large antennas with a minimum diameter of 2 3 m. 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. 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. The most popular frequency bands available on satellite are l band s band c band x band ku band k band and ka bands.

Most of the amateur radio frequency bands have a satellite allocation sub band. C band x band ku and ka frequency bands used for satellite communications. Characteristics of the shf frequency band frequency. L band 1 2 ghz global positioning system gps carriers and also satellite mobile phones such as iridium.

To prevent interferance caused by multiple sites transmitting on the same frequencies government agencies and standards organizations around the globe try to keep the usage organized and often such controls take the form of government regulations which carry the weight. The most popular bands for these satellites are the 144 146 and 435 438 mhz bands.
