Question 8 (15 points): A geostationary satellite takes a digital photo of the Earth in every minute. The satellite sends the photo to the base station via a microwave link with a bandwidth of 5 Mbps. What is the maximum size of the photos that can be taken every minute without causing any queuing delay on the satellite? At this size, how long is the total delay from the moment when the satellite starts sending a photo (i.e., when the first bit is sent) to the moment when the entire photo is received at the base station (i.e., when the last bit is received)? Please look up how high the orbit of a geostationary satellite is from the surface of the Earth and how fast the microwave signal propagates in the vacuum. Let us assume the base station is right below the geostationary satellite and the entire path between them is in vacuum for simplicity.
