Consider a communications satellite in geosynchronous orbit. It sits approximately 35,786 km above the earth's equator. What is the transmission delay that would be expected for a data packet to travel from one ground station to another via this satellite? (You may make the simplifying assumption that the data packet travels at the speed of light in a vacuum.)
b) Consider a "long haul" cable that is 100 km in length. Assume that the propagation speed in the cable is 2/3 the speed of light in a vacuum. What is the transmission delay through this cable? (In other words, how long does it take for a single bit to travel from one end of the cable to the other?)
