FAA says 5G could impact radio altimeters on most Boeing 737s
If I understand this correctly, the FCC has allocated the 4.2GHz-4.4GHz band for radar altimeters. The FCC has also allocated the 3.7GHz-3.98GHz band to 5G. It turns out that the radar altimeters, as manufactured, use spectrum outside their allocated band, down to and including part of the 3.7GHz-3.98GHz 5G band.Am I missing something?If a rancher buys a plot of land from 34.42°N to 34.44°N to graze his cattle on, but in actual fact grazes his cattle all the way from 34.37°N to 34.47°N. Then a farmer buys a plot of land from 34.37°N to 34.398°N to grow wheat on. Does the rancher still get to herd his cattle down to 34.39°N to feed his cattle? The cattle have to eat, after all, and cutting down the grazing land by 30% could cause some cattle to starve to death. And the rancher has a vested financial interest in ensuring his cattle are well fed, and that wheat is good eating. And the rancher has always been grazing his cattle there, what right does the farmer have to till the soil on the racher's grazing land? And we, the American public, have the right to buy beef. Why should the farmer purchasing 34.37°N to 34.398°N interfere with my ability to buy a steak?Does any of this make any sense to anyone?Unless there's additional information I'm unaware of, it seems as if the design and/or manufacture of the radar altimeter is not fit for purpose. Using 3.7GHz to 3.98GHz for 5G doesn't break the radar altimeters; the radar altimeters are already broken and must be fixed or grounded, because the equipment is broken and unsafe.If 5G equipment is emitting outside of its allocated 3.7-3.98GHz spectrum then the FCC needs to drop a brick on that of course.
