Suppose there is a 10 Mbps microwave link between a geostationary satellite and its base station on Earth. Every minute the satellite takes a digital photo and sends it to the base station. Assume a propagation speed of 2.4 _ 108 meters/sec.

a. What is the propagation delay of the link?

b. What is the bandwidth-delay product, *R *· *d*prop?

c. Let *x *denote the size of the photo. What is the minimum value of *x *for the microwave link to be continuously transmitting?

a)

The Distance between geostationary satellite and earth (d) = 3.6*10^{7} meters

The Propagation speed (s) = 2.4*10^{8} meters/sec

The Transmission rate(R) = 10Mbps
