3. What is the latency of a call originating at the North Pole to reach the South Pole if the call is routed via 6 satellites? Assume that the switching time at each satellite is 10 microseconds, the earths radius is 6371 km, and the altitude for each satellite is 750 km. We also assume the signal propagates in light speed 300,000 km/second. Compute the total distance : Compute the time travel the distance : Compute the total latency : Solution
