| FAA Statement on 5G |

The FAA believes the expansion of 5G and aviation will safely co-exist. Today, we took an important step toward that goal by issuing two airworthiness directives to provide a framework and to gather more information to avoid potential effects on aviation safety equipment. The FAA is working closely with the Federal Communications Commission and wireless companies, and has made progress toward safely implementing the 5G expansion. :palm: https://www.faa.gov/newsroom/faa-statement-5g Can’t they just coordinate with FCC before FCC put the 3.7GHz C-band out for suction :-// Edit: Fixed the URL, thanks @tooki |

1. Here’s a non-mangled, clickable URL: https://www.faa.gov/newsroom/faa-statement-5g 2. You don’t understand the point of the FAA’s role or standpoint in this matter, do you? Their job, as the agency responsible for aviation safety rules, includes defining the rules and requirements for aviation equipment. And that in turn means they are responsible for approving radio altimeters, and defining the requirements for them. Why does this earn a facepalm from you? |

I have no particular issue with the FAA's actions except that they're too late. 5G should never have been in the same band as navigation aids. To me, this is the screw-up of the FCC. That two governmental agencies can't coordinate a coffee break comes as no surprise. This could turn out to be a really big problem! |

It's not just a coordination issue IMHO - it's a complete screw-up of the FCC as you just said. It was THEIR duty. It's their job to coordinate frequency bands use and allocation. Isn't it? |

My opinion on the matter is the aircraft equipment manufacturers got away with being able to cheap out on filtering and not making their receivers selective as they had no RF neighbors at the time. The altimeters operate from 4.2-4.4ghz and the C-band 5G equipment is operating under 4ghz. If your equipment can't deal with a transmitter operating 200MHz away thats lazy design. I get there can be out of band harmonics and whatnot but there are acceptable emission standards for that and your receiver should be prepared to cope with it. I don't think the FCC and cellular companies are the bad guys here. Buy a couple of these and move on with life https://www.minicircuits.com/WebStore/dashboard.html?model=ZVBP-4300-S%2B |
