A. can reach over a larger geographical area
B. circuits cost independent of distance
C. broadcast possibilities
D. none of the above

Answer 1

Hint: The satellite communication is having a lot of uses in our life. They can be used for mobile and wireless communication applications without depending on location. With just one satellite itself, a wide area of region can be covered. It provides wider bandwidth based on allocation types.

Complete answer:
Let us discuss the advantages of satellite communication.
- Satellite communication is used for the transmission of information like voice, data and video.
- They are used for the availability of internet services.
- The GPS services are also possible using this.

This kind of communication will make it easy to obtain services from a single provider and the service is uniformly made available. It is having a wide opportunity in the field of weather forecasting, radio/TV signal broadcasting, getting intelligence in the military, navigation of ships and aircrafts, global mobile communication, connecting remote areas etc. It can cover a wide area of the earth surface or a whole country. Therefore a single satellite is enough for a whole country. These can be useful in the field of broadcasting also. Therefore all the options available in the question are the advantages.

So, the correct answer is “Option D”.

Note:
There are disadvantages also for satellite communication. Satellite manufacturing needs a larger time. And also satellite design and development will take up higher cost. Once a satellite is launched it should be monitored and controlled on the regular intervals of period so that it remains in orbit. The satellites have a validity of about 12-15 years. Because of this, the next launch should be planned accordingly even before the present one gets dysfunctional.
