Yes, I know this is a sports board, and I apologize to those whose delicate sensibilities I offend. This question has been nagging at me for a little while now though, and I know there are plenty of people here who will have insight on this topic that I am just not getting.
So I keep hearing stories about the airlines wanting to stop 5G from being implemented. The phone companies keep pushing the rollout date back, but the airlines sound like they want it blocked altogether, so I went to Google to see if I could figure out why. I welcome any feedback on my comments here in case I have misunderstood.
From what I understand the airlines use a radio band between 4.2 GHz and 4.4 GHz to track their altitude. (Thanks ham radio license for helping me understand what this means!) 5G in the US (it is different in different parts of the world) will use a radio band between 3.7 GHz and 3.98 GHz, thus staying outside the 200 Hz buffer recommended by the FCC. The airlines are saying that the buffer is not enough, as signals could bleed through the buffer (like on an old radio when you were in between two stations and could hear both stations simultaneously) and possibly interfere with their altimeters.
Now the airlines could install filters to make their equipment more sensitive, but instead they are arguing that it is better to block technological advancement so that they do not have to change. And the fact that they are threatening to ground flights if they don’t get their way seems crazy to me. It is like if the airlines were in one lane on the freeway and 5G were in another lane, the airlines are threatening to pull off the freeway and stop what they are doing if 5G drives anywhere near them. It just doesn’t make sense to me.
Again, if I am misunderstanding the issue, I hope someone here can educate me so that I can see what the problem actually is. Oh, and even though the question is technical in nature, Go UTES!
