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 must a satellite have distinct uplink and downlink frequencies?
In order to avoid interference , the satellite must have distinct uplink and downlink frequencies. The satellite receives the signal on one frequency and it transmits on another frequency, the reason is to avoid the interference of signals. … To obtain clear transmission, the frequency must be distinct between them.
Read moreWhy the uplink and downlink frequency are not same?
It’s because lower frequencies get reflected by atmospheric bands and cannot penetrate to get through to the satellite . … Therefore, mobile-to-base station (uplink) frequencies are lower than base station-to-mobile(downlink) frequencies.
Read moreCan the same frequency be used for uplink and downlink communication?
The uplink and downlink transmitters use separate frequency bands for transmissions ; therefore, both downlink and uplink transmitters can transmit at all times and at the same time [3].
Read moreWhy frequency band for uplink and downlink is different in transmission of microwaves through space?
Answer: Uplink frequency is kept higher than Downlink frequency for the following reasons: At higher frequency attenuation is more hence more power will be required for signal transmission to ensure that it reaches the destination with the required minimum power .
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.
Read moreWhat is the uplink frequency of satellite?
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. … downlink and uplink.
