6. Suppose there is a 10Mbps 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 s=2.4108meters/sec. a. What is the propagation delay of the link? b. What is the bandwidth-delay product, Rdprop ? c. Let x denote the size of the photo. What is the minimum value of x for the microwave link to be continuously transmitting
