WebAbout 35 percent of all terrestrial communication is maintained by microwave radio relay systems. There are various types of microwave radio communication systems, operating anywhere between 15 miles to 4,000 miles, including feeder service or intrastate microwave systems and long-haul microwave systems. Webcommunications-satellite and terrestrial microwave relay systems which share the common car rier frequency bands at 4 and 6 GHz. Since mutual interference can occur in two distinct modes, satellite-to-terrestrial, or downlink mode, and terrestrial-to-satellite, or uplink mode (see Fig ure l),the experiment will be performed in two phases.
