Exercise 4. Suppose there is a 10 Mbps link between a geostationary satellite A and its base station on Earth. Every minute the satellite takes a digital photo and sends it to the base station. Assume the propagation speed of 2.5 x 10 meters/ sec. (a) What is the propagation delay of the link? (b) What is the bandwidth-delay product? (c) Let T denote the size of the photo. What is the minimum value of T for the microwave link to be continuously transmitting? (d) Suppose the transmission has to be further carried out from base station to the next geostationary satellite. What wi be the overall transmission delay in that case from satellite A to satellite B assuming the transmission rate to be the same and the size of the photo equal to the one calculated in part (c) Assume: Distance between the satellite and the earth is 22369.363 miles
