Right. From his article:
But in any event, in the face of rules adopted by about 40 or so other countries, the aviation industry needs to show why the U.S. is different.
And if he did *any* real research at all: https://www.airside.aero/magazine/articles/5g-vs-the-radar-altimeter
In most of the world, RAs are not affected by 5G, because 5G signals most commonly radiate in the 900MHz, 1.8, 2.3, 2.5 and 3.5 GHz bands, leaving a safe 800MHz between 5G and RA bands. However, in the USA, demand for high-speed data on cellular devices has led to the Federal Communications Commission (FCC) auctioning additional bands in the C-band range between 3.7-3.98 GHz, only 200 MHz below the RA band.
And here are some actual test results: https://www.rtca.org/wp-content/uploads/2020/10/SC-239-5G-Interference-Assessment-Report_274-20-PMC-2073_accepted_changes.pdf All of that, combined with the real world deaths of people who died as a result of radar altimeter failures, suggest to me that Harold Feld did not really do a much better job in November.
