Verizon, at & T, and the FCC have reached an agreement with the Department of transportation. For Verizon, delaying the launch of the’C-band’ spectrum means canceling a celebration scheduled for 1pm et on Tuesday.

A two-week delay promises the certainty of bringing the nation our game-changing 5G network in January, says Verizon.

At & T has voluntarily agreed to an additional two-week delay of our deployment of C-band 5G services. We remain committed to the six-month protection zone mitigations we outlined in our letter.

Faa communications deputy assistant administrator Jeannie shiffer says safety is the core of our mission. The FAA thanks at & T and Verizon for agreeing to a voluntary delay and for their proposed mitigations.

The agreement will see mitigations put in place around 50 airports for six months. The FAA says the U.S. standards and operating environments are unique.

At & T CEO John Stankey and Verizon CEO Hans Vestberg spoke out about their proposal. They said they would be an’irresponsible abdication of the operating control required to deploy world-class and globally competitive communications networks’.

The executives continued to propose mitigations like the ones used in France. Creating a buffer zone around certain airports and lowering power levels nationwide.

The 5G signal could interfere with the accuracy of an airplane’s radio altimeter, according to the FAA. The FAA claims that rolling out the changes could disrupt air travel or impact safety safety safety.

T-Mobile currently uses mid-band spectrum that is n’t in the C-band. Verizon and at & T are eager to roll it out so that the new spectrum will provide in-between performance over much wider areas.
