Question 20

In satellite communication, the uplink frequency band used is:

Solution

In satellite communication, different frequency bands are used for uplink and downlink to avoid interference.

For the C-band satellite communication:

- Uplink frequency: 5.925 - 6.425 GHz

- Downlink frequency: 3.7 - 4.2 GHz

The uplink frequency is higher than the downlink frequency because higher frequencies require more power, and it is easier to generate higher power at the ground station than on the satellite.
