Question

Disadvantages of satellite communication over terrestrial communication

Answer 1

Answer:

Apart form advantages Satellite Communication also posses some disadvantages that are as follows:

Number-1: With the Satellite in position the communication path between the terrestrial transmitter and receiver is approximately 75000 km long.

Number-2: There is a delay of ¼ sec between the transmission and reception of a signal because the velocity of electromagnetic wave is 3* 10^5 Km/second.

Number-3: The time delay reduces the efficiency of satellite in data transmission and long file transfer, which carried out over the satellites.

Number-4: Over-crowding of available bandwidth due to low antenna gains is occurred.

Number-5: High atmosphere losses above 30 GHz limit the carrier frequency.
