Uplink And Downlink Frequency In Satellite Communication

In europe ku band downlink is used from 10 7 ghz to 12 75 ghz for direct broadcast satellite services such as astra.

Uplink and downlink frequency in satellite communication.

5925 mhz to 6425 mhz is uplink band where as 3700 to 4200 mhz is downlink band. Pertaining to radiocommunication service a downlink dl or d l is the portion of a feeder link used for the transmission of signals from a space radio station space radio system or high altitude platform station to an earth station. Primarily used for satellite communications for full time satellite tv networks or raw satellite feeds. 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.

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. In the context of satellite communications a downlink dl is the link from a satellite to a ground station. What are uplink and downlink. 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.

So lets suppose that bts as in case of gsm transmits using low frequency on the downlink. The satellite transmitter generates a signal that would jam its own receiver. Used for satellite communications. When an uplink is being received by the spacecraft at the same time a downlink is being received by earth the communication is called two way.

The direction from vsats to sallite is known as uplink and the direction from satellite to vsats is known as downlink. If both uplink and downlink shared the same frequency. Communication systems uplink and downlink frequency please watch. 6ghz band frequency is used for uplink and 4ghz frequency band is used for downlink in c band satellite communication operation.

The communication going from a satellite to ground is called downlink and when it is going from ground to a satellite it is called uplink. High frequency means higher attenuation. I was able to gather some answers as to why is so.
