Intensive talks were continuing Monday aimed at heading off a impasse between U.S. wireless firms and the aviation sector that could significantly disrupt flights starting Wednesday.
On Sunday, the chief executives of AT&T and Verizon Communications rejected a request to delay the planned Jan. 5 introduction of new 5G wireless service over aviation safety concerns but offered to temporarily adopt new safeguards.
The aviation industry and FAA have raised concerns about potential interference of 5G with sensitive aircraft electronics like radio altimeters that could disrupt flights.
AFA-CWA President Sara Nelson, who represents 50,000 flight attendants at 17 airlines, urged wireless carriers to agree to a 10-day deployment delay to finalize precautions.
