The uplink frequency is the frequency which is used for transmission of signals from earth station transmitter to the satellite. The downlink frequency is the frequency which is used for transmission of signals from the satellite to the earth station receiver.
Read moreWhat is the meaning of 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 .
Read moreWhy is uplink and downlink frequency different?
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 meant by uplink?
Definition of uplink 1 : a communications channel for transmissions to a spacecraft or satellite also : the transmissions themselves. 2 : a facility on earth for transmitting to a spacecraft or satellite.
Read moreWhy downlink frequency is lower 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.
Read moreWhy uplink and downlink frequency is different?
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 are uplink and downlink frequencies not the same in satellite Mcq?
Explanation: The original signal being transmitted from the earth station to the satellite is called the uplink , and the re-transmitted signal from the satellite to the receiving stations is called the downlink. … As a result, most satellites contain multiple transponders, each operating at a different frequency.
