Commissioning, initially scheduled for December 5, had already been postponed and was due to take place on January 5. But the European aircraft manufacturers Airbus and the American Boeing have recently expressed their
worry about possible 5G interference with aircraft radio altimeters.
The US Secretary of Transport, Pete Buttigieg, and the boss of the US aviation regulator (FAA), Steve Dickson, have therefore proposed this new commissioning deadline, in a letter sent Friday to AT&T and Verizon, two of the main telephone operators in the country.

AT&T also indicated that it has received the letter and is reviewing it.
The 3.7-3.8 GHz frequency bands were awarded to AT&T and Verizon in February, following a tender for tens of billions of dollars.
They had, however, agreed in early November to postpone the launch to January, in the face of concerns from theFAA regarding potential interference issues with aircraft measuring altitude in airplanes, and requested additional information on these instruments, which operate in frequency bands that can be used for 5G.
TheFAA has also issued new directives limiting the use of these on-board devices in certain situations. American airlines have expressed their concern over the potential costs incurred, and called on the authorities to quickly find a solution.
In a joint letter sent at the end of November to the Federal Communications Commission (FCC), which oversees the deployment of 5G in the country, AT&T and Verizon had explained that they wanted to proceed with this deployment in January, but take measures until July 2022. precaution in addition to those already provided for by law, while theFAA carries out its analyzes.
