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.
Read moreWhy uplink and downlink frequencies are different in satellite communication?
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.
Read moreWhat is meant by downlink?
: to transmit (data) from a spacecraft or satellite to a receiver on earth .
Read moreWhich frequency is used in satellite communication?
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 …
Read moreWhat is the wavelength of satellite communication?
When considering the range of radio frequencies for satellite communications, say from around 300 MHz to 30 GHz, the free-space wavelength varies from 1 m to 1 cm .
