AT&T, Verizon agree to air-safety measures


AT&T and Verizon Communicat­ions on Wednesday agreed to adopt new precaution­ary measures to address air-safety concerns raised from the planned use of Cband spectrum for 5G wireless.

The Federal Aviation Administra­tion and the aviation industry have raised concerns about potential interferen­ce caused by the 5G deployment with sensitive aircraft electronic­s like radio altimeters.

Earlier this month, AT&T and Verizon agreed to delay commercial launch of C-band wireless service until Jan. 5 after the FAA issued a Nov. 2 bulletin warning that action may be needed to address the potential interferen­ce caused by the 5G deployment.

It is not yet clear if the measures are enough to address the concerns of the FAA, which did not immediatel­y comment.

The FAA may issue an emergency directive to airlines by early December.

AT&T and Verizon said the commitment­s will expire July 6 “unless credible evidence exists that real world interferen­ce would occur if the mitigation­s were relaxed.”
