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.
Read moreWhy uplink and downlink frequencies are different in mobile communication?
Since a mobile station (cellphone) cannot afford to transmit at high power to compensate for this loss, it must transmit on a lower frequency as a lower frequency presents lesser free space path loss. Therefore, mobile-to-base station (uplink) frequencies are lower than base station-to-mobile(downlink) frequencies.
Read moreWhat is the uplink and downlink frequency in GSM?
The uplink frequency range specified for GSM is 933 – 960 MHz (basic 900 MHz band only). The downlink frequency band 890 – 915 MHz (basic 900 MHz band only).
Read moreWhat is uplink and downlink frequency in satellite communication?
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 moreWhy do we use 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.
