Question

Suppose there is a 10 Mbps microwave link between a geostationary satellite and its base station on Earth. Everyminute the satellite takes a digital photo and sends it to the

base station. Assume a propagation speed of 2.4* 108meters/sec. Note that geostationary satellite is d = 36,000 kilometers away from earth surface. (a) What is the propagation delay of the link? (b) What is the bandwidth-delay product, R · dprop? (c) Let x denote the size of the photo. What is the minimum value of x for the microwave link to be continuouslytransmitting?
