The C-band antennae are directional, laterally, generally in three lobes 120 degrees apart. For cellular C band, they will be low power. No point in wasting power radiating UP.
This is much ado about nothing.
C-band is used for example at San Diego Naval air station.
Agreed...all about nothing except one thing.
China wants control of 5G and so far, Intel, Apple and Qualcomm have prevented this from happening.
Watch for President Poopy to cut a deal for China.
Ah, but that’s science, not politics! Might as well let Doc Fauci set 5G policy.
-—no point in wasting power radiating UP—So you’re saying that a geek’s 5G phone won’t work OVER an airport. How about UP in hi-rise buildings? My reading on the capability of this tech says the high freguency/ low power nature of this tech requires relays much closer to the user.
And is this stuff the thing that causes Havana Syndrome: microwaves too close to people’s heads? And when getting close to an airport can you assure us that our altimeters will work OK? The Missouri rule is in effect here.
