Problem
Suppose satellites are placed in geosynchronous orbit around the equator at 3° intervals. An Earth station with a 1-m parabolic antenna transmits 100 watts of power at 4 GHz toward the intended satellite. How much power is radiated toward the adjacent satellites on either side of the intended satellite? What implications does this amount of power have about low-power and high-power signals on adjacent satellites? What does it imply about the diameter of Earth station antennas?
