In satellite communication, the uplink frequency band used is :
Updated On: Jan 13, 2025
- 76 – 88 MHz
- 3.7 – 4.2 GHz
- 5.925 – 6.425 GHz
- 420 – 890 MHz

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
In satellite communication:
- The uplink frequency band is used for transmitting signals from an earth station to a satellite.
- The downlink frequency band is used for transmitting signals from a satellite to an earth station.
Uplink frequencies are generally higher than downlink frequencies to minimize interference.
Common Standard Frequency Bands:
- Uplink: \( 5.8 - 6.2 \, \text{GHz} \)
- Downlink: \( 4.0 - 4.2 \, \text{GHz} \)
Analysis:
The frequency band \( 5.925 - 6.425 \, \text{GHz} \) falls within the standard uplink frequency range for satellite communication.
Final Answer:
The uplink frequency band used in satellite communication is \( 5.925 - 6.425 \, \text{GHz} \).
