Base station on Earth
1. 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 dprop?
c. Let x denote the size of the photo. What is the minimum value of x for the microwave link to be continuously transmitting?
