In the satellite communication, the up linking frequency range is

Options

A. 0.896 to 0.901 GHz
B. 0.420 to 0.890 GHz
C. 5.925 to 6.425 GHz
D. 3.7 to 4.2 GHz

Answer

To solve the question regarding the uplinking frequency range in satellite communication, we can break down the information provided in the video transcript into a structured format.

### Step-by-Step Solution:

1. **Understanding Satellite Communication**:
- Satellite communication involves transmitting signals between Earth and satellites in space. There are two main types of frequencies used: uplink frequency and downlink frequency.

2. **Defining Uplink and Downlink Frequencies**:
- **Uplink Frequency**: This is the frequency of the signal sent from Earth to the satellite.
- **Downlink Frequency**: This is the frequency of the signal sent from the satellite back to Earth.

3. **Frequency Ranges**:
- The uplink frequency must be higher than the downlink frequency. This is because the uplink signal has to pass through various layers of the Earth's atmosphere, which can attenuate the signal. Therefore, a higher frequency is required to ensure that the signal can reach the satellite effectively.
- Conversely, the downlink frequency can be lower because the satellite is already in space, and the signal does not have to pass through as many atmospheric layers.

4. **Specific Frequency Ranges**:
- According to the information provided, the uplink frequency range is specified as between **5.925 GHz to 6.425 GHz**.
- The downlink frequency range is stated to be between **3.7 GHz to 4.2 GHz**.

5. **Conclusion**:
- The correct answer to the question regarding the uplinking frequency range in satellite communication is **5.925 GHz to 6.425 GHz**.

### Final Answer:
The uplinking frequency range in satellite communication is **5.925 GHz to 6.425 GHz**.
