Re: Protectionism ?
With the latest update from the FAA (which has now cleared more specific RADAR altimeters for use), this seems just like a pissing contest for "who pays to (re-)certify RADAR altimeters that were not properly tested before because the chunk of C-band that they encroached on was previously only used by TV broadcast downlinks..."
There is no serious _technical_ doubt that, regardless of the power level of the 5G signal, that a properly designed RADAR altimeter should function perfectly well. And the FAA implicitly acknowledge that, by clearing some altimeter's for use in the 5G environment... but not all. So what we're left with is whether the FCC should pay the avionics manufacturers to fix their devices (which used to work just fine, remember... because there were no widely-deployed lower-C-Band transmitters) or whether the avionics folks should fix their own darn products.
Now, as it happens, the senior Republican US Senator is from Iowa (Chuck Grassley). And entirely coincidentally, Rockwell-Collins is based in Iowa.
Guess who makes RADAR Altimeters for the B777...?
