IT House January 4 news, Reuters said that according to a previously unreported letter, U.S. transportation officials informed wireless carriers that after January 19, if there is no "unforeseen aviation safety issues", it will not seek any further details about the deployment of 5G wireless services.
As we all know, the current 5G deployment in the United States is widely used in millimeter wave, and the main reason behind this is that Sub-6GHz is in the hands of other fields, and it is difficult for operators to obtain sub-6GHz or less spectrum.
In December 2021, the U.S. Department of Transportation and the U.S. Federal Aviation Administration filed a request to wireless carriers to postpone upcoming services for aviation safety reasons. So AT&T and Verizon proposed limiting 5G signal power to 6 months to give regulators more time to study how they would affect aircraft operations.
IT House understands that in early November 2021, AT&T and Verizon agreed to postpone the new 5G band scheduled for December 5, 2021, to January 5, 2022, so that it can work with the FAA to resolve concerns about potential disruption to critical cockpit safety systems.
U.S. Transportation Secretary Pete Buttigieg and Federal Aviation Administration Administrator Steve Dickson said in a joint letter from AT&T and Verizon Communications that delaying C-band wireless deployments by two weeks could "give us more time and space to reduce the impact on commercial flights." ”
The accompanying "Final Term Sheet" states that unless "unforeseen aviation safety issues" arise, agencies "will not seek or require further delays in all or part of C-band deployments, including delays in resuming day-to-day operations." ”
