Suppose a 512kbps point-to-point link is set up between the Earth and a rover robot on the Mars. The closest distance between the Earth and the Mars is 55Gm (55*10^9 m), and data travels in speed of light (3*10^8 m/s).

a) calculate the minimum RTT for the link.

b)the rover is taking a picture of 5MB and sending the picture back to the Earth. Assuming there is not transmission error or other latency, how quickly after the picture is taken can it reach the Earth?

c) the rover uses 4GHz frequency to transmit the picture. The rover’s transmission power is 200W. The transmission antenna gain is 10,000 and the receiving antenna gain is 100,000. What is the received signal strength at the Earth’s station, in W (assume Pi = 3.14)?
