5G signals can interfere with meteorological remote sensing satellites. This is because the microwave emissions of the atmosphere are at power levels typically much smaller than the 5G aggregate broadcasts in high bands greater than 20 GHz. The problem is not simple; the amount of interference depends on multiple factors occurring simultaneously. Different meteorological remote sensing satellites have multiple bands which are sensitive to 5G broadcasts. Each of these satellites may be sensitive to different 5G frequencies and power levels. The problem is not just limited to meteorological satellites, other satellites may also be interfered with. On the other hand, 5G is not just in one band but covers many frequencies. In addition, there is not just one broadcast for any given location, but there is a potential for thousands of individual user equipment broadcasts at a given location. Although this is a problem covering the entire land surface of the Earth, each individual geographic location may be broadcasting at different and multiple frequencies. All the variability with respect to the satellites and the 5G broadcasts make this problem difficult to solve. This presentation will describe a simple, deployable solution minimizing impacts to 5G users while eliminating the potential impacts to meteorological remote sensing satellites.
