Uplink And Downlink Frequency Range In Satellite Communication

In satellite telecommunication a downlink is the link from a satellite down to one or more ground stations or receivers and an uplink is the link from a ground station up to a satellite.

Uplink and downlink frequency range in satellite communication.

Digital satellite uplink chain. The direction from vsats to sallite is known as uplink and the direction from satellite to vsats is known as downlink. These terms should not be confused with downstream and upstream. However due to the lower frequency range it performs better under adverse weather conditions on the ground.

Now as would have thought separate frequency bands are always allocated for uplink and downlink signals often separated by a gap maybe for future allocation since the span of guard bands. 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. 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. Used for satellite communications.

With the variety of satellite frequency bands that can be used designations have been developed so that they can be referred to easily. Ka band 26 40 ghz communications satellites. 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. 5925 mhz to 6425 mhz is uplink band where as 3700 to 4200 mhz is downlink band.

Communication systems uplink and downlink frequency please watch. 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. Because of its weaker power it requires a larger antenna usually above 1 8m 6ft. Some companies sell uplink and downlink services to television stations corporations and to other telecommunication carriers.

The c band is primarily used for voice and data communications as well as backhauling. 6ghz band frequency is used for uplink and 4ghz frequency band is used for downlink in c band satellite communication operation.
