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 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 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.

Read moreWhat is an uplink signal?
Uplink refers to the signal leaving your device and returning to the cell tower , while downlink refers to the signal coming to your device from the cell tower. All cellular devices, including smartphones and tablets, work within 3G, 4G, 5G RF (radio frequencies).
Read moreWhat is uplink and downlink frequency range?
6GHz band frequency is used for uplink and 4GHz frequency band is used for downlink in C band satellite communication operation. 5925 MHz to 6425 MHz is uplink band where as 3700 to 4200 MHz is downlink band.
