Why the uplink frequency is greater than the downlink frequency?
In satellite communication, the uplink frequency is higher than the downlink frequency because the attenuation level increase with an increase in frequency. The power at the ground station (Base Station) is more than compared to the power available at the satellite.
What is the relationship between the satellite uplink frequency and downlink frequency?
Uplink frequency is the frequency at which, the first earth station is communicating with satellite. The satellite transponder converts this signal into another frequency and sends it down to the second earth station. This frequency is called as Downlink frequency.
What is swamping in satellite communication?
The local strong signal transmitter would totally desensitise the receiver and as a result the receiver would “hear’ little to nothing of the weak signal coming from a distance. ie. the transmitter would “swamp” the receiver.
What will happen if uplink and downlink frequencies are same?
If the uplink and downlink frequencies are the same, you will have what is called a ‘simplex’ radio system. Either the uplink or the downlink transmitter can send at any one time, while the other receives. Both transmitters, and receivers can not be used at the same time.
Why the satellite downlink frequency is less than the uplink frequency?
It say basically the power at ground stations is more as compared to power available at satellites.So generally frequency for uplink is kept higher than the downlink. There is greater attenuation due to rain when the signal frequency is high.so downlink is also kept at lower frequency.
What is the uplink frequency of satellite?
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….downlink and uplink.
| Frequency Band | Downlink | Uplink |
|---|---|---|
| C | 3,700-4,200 MHz | 5,925-6,425 MHz |
| Ku | 11.7-12.2 GHz | 14.0-14.5 GHz |
| Ka | 17.7-21.2 GHz | 27.5-31.0 GHz |
What is satellite uplink and downlink?
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. Basically any signal from the ground to satellite can be known as Uplink.
Why downlink frequency is lower than the uplink frequency?
Why uplink frequencies are always less than downlink frequencies?
