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 is it that the uplink is always higher in frequency than the downlink?
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 moreWhat is the difference between uplink and downlink in networking?
What is uplink and downlink in mobile communications? An uplink is a signal leaving your mobile phone and transmitting it to a cell tower. A downlink is a signal transmitting to your mobile phone from the cell tower .
Read moreWhat is meant by uplink and downlink frequency?
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 moreWhat is the 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 .
