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.
Read moreWhat will happen if uplink and downlink frequencies are same?
The satellite transmitter generates a signal that would jam its own receiver ; if both uplink and downlink shared the same frequency.
