Verizon and AT&T have agreed to further delay a rollout of 5G services after pressure from airlines, regulators and the White House.
They worry the carriers' use of the C-band wireless spectrum for 5G may interfere with sensitive aircraft electronics like radio altimeters that could disrupt flights.
The agreement pushes back the rollout by two weeks to Jan. 19.
Verizon said despite the delay, it still, QUOTE: "promises the certainty of bringing this nation our game-changing 5G network in January."
While, AT&T said it agreed to the delay at the request of Transportation Secretary Pete Buttigieg.
The move is a reversal by the two groups, whose chief executives on Sunday pledged to stick with the schedule agreed in November.
The FAA praised the companies for agreeing to the additional delay.
Over the next two weeks the regulators, airlines and wireless carriers will look at ways of minimizing the potential impact of 5G rollout.
Both companies have already agreed not to deploy 5G around airports for six months.
