v17 v18 7 7 If two signals are sent at the same frequency, they can conflict with each other. Therefore, there are spectrum licenses in each country which are earmarked for specific purposes, such as TV or phone use. Each user must stay within their allotted bandwidth (the portion of the spectrum which they own the license to) on the power-frequency plot, but as they are wave shaped, they do not naturally fit perfectly. Ideally they would appear rectangular, so as to maximize the amount of power that could be sent while staying within the intended bandwidth. In lower frequency signals, this issue is solved by having license owners designate the edges of their spectrum to be buffer zones according to FCC rules (in the United States), but this could be less effective at higher frequencies where waves will likely have a greater amount of spillover or leakage. 8 8 9 This issue is particularly coming to a head with the advent of 5G, which is relying on using higher frequencies to have enough spectrum. Weather prediction technology analyzes waves at about 23.8 GHz, and could be disrupted by leakage from 5G. This project aims to get a general idea about how much potential leakage there might (or might not) be.9 This issue is particularly coming to a head with the advent of 5G, which is relying on using higher frequencies to have enough spectrum.
