Problem 1. A geostationary satellite is located 36,000 kilo- meters (km) away from the surface of the Earth. Once a minute it takes a digital picture and transmits the data to a base station on Earth. The rate of transmission is 10 Mbps and the propogation speed is 3.0 × 108 m/s. You may assume the actual time required to take the picture is negligible. a. What is the propagation delay of the link? b. The bandwidth-delay product is defined to be Rxdprop where dprop is the propagation delay. Calculate the bandwidth-delay product Rxdprop where deprop is the propagation delay. c. Let x denote the size of the picture in bits. What is the minimum value for x so that the satellite is continuously transmitting data over the link?
