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 the difference between 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 downlink data rate is higher than uplink?
The allowable pathloss for Downlink is more compared to that of the Uplink. (Because UE TX power is limited and NodeB power is much higher ). Hence the data rate in the downlink is higher compared to that in the uplink.
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 moreWhat is downlink frequency?
The communication between satellite towards earth station receiver is known as downlink frequency. Downlink frequency of satellite is the frequency at which the satellite is transmitting the signal and earth station receiving it. Downlink frequency range = 3.7 GHz to 4.2 GHz.
