By letter dated 31 December 2021, the Secretary of Transportation and FAA Administrator have documented an interim plan and solution to the 5G interference issues. The letter is on Secretary Buttigieg's letterhead though it bears the signatures of both senior officials (something a lawyer
would pause to note, but anyway) - here is the link to the FAA website and the letter:
DOT and FAA Letter to ATT and Verizon executives on 5G
For those possibly too uninterested or unconcerned to read it closely, the basic point of this development is to push back the start date for 5G service by these two companies by two weeks, to continue what evidently has been a constructive dialogue between FAA (and DOT to the extent the 'mother-ship' federal agency is involved at levels above FAA proper) and the two service providers (ATT and Verizon). Also, the letter outlines a way of segmenting the problem, so that some areas around certain airports would not see 5G introduction until more is known about potential interference modalities and solutions. There also is a role being pitched for AMOCs, Alternative Means of Compliance. It's just two pages, give it a read.
Not least, in the eyes of this SLF/attorney, there is nice language at the end about the predominant significance and critical importance of aviation safety in the United States. "Aviation nation" - kinda has a nice cadence to it, I think I could self-load to it.
