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.
Read moreWhat is uplink and downlink signal?
Uplink and downlink, also called upload and download, refers to the two-way communication between a cell tower and your phone . Downlink definition – signal coming from a cell tower to your cellular device. Uplink definition – signal leaving your cellular device and going back to a 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 .
