I already said s-band (which is 2-4ghz) specifically. BRS/EBS (2.5-2.7ghz) has no meaningful guard band to protect s-band radar, and the radars, at least when used on military vessels, are actually dramatically more sensitive than aviation radar altimeters. And not only has EBS/BRS been operating for decades without any problems, but a) the maritime radar emission/detection patterns are horizontal, just like telecom/television, which should produce more interference than the perpendicular patterns of radar altimeters, and b) EBS has operated for 3 decades using television broadcast power levels...1000s of watts as opposed to the 100s of watts that telecom uses. If interference was actually a problem, the DoD would have shut down those two bands back in the 80s.

Franky speaking, everybody here is talking out of their asses, and just rehashing bullshit that they get told. I'll lowbrow dismissal that all day long because it doesn't deserve and inch more of effort.
