Download Solution PDFThe Correct Answer is : 3) more than the critical frequency of the ionosphere
Explanation:
-
The ionosphere reflects radio waves below a certain frequency known as the critical frequency (usually below 30 MHz).
-
For satellite communication, signals must pass through the ionosphere and not be reflected.
-
Therefore, the frequency must be greater than the ionosphere's critical frequency to ensure penetration into space.
Additional Information
-
Uplink: 5.9 – 6.4 GHz
-
Downlink: 3.7 – 4.2 GHz
-
These are well above the critical frequency of the ionosphere.
