According to a report on The Verge website on January 3, mobile operators Verizon and AT&T rejected the request of to delay the launch of IF 5G services from the Federal Aviation Administration of the United States .
At the beginning of this year, US Federal Communications Commission auctioned the rights of two operators to use the so-called "C-band" frequency at a price close to US$70 billion. Both Verizon and AT & T are eager to introduce this feature so that in addition to providing ultra-fast 5G connections in specific areas, they can also use high-frequency millimeter wave technology to provide much slower 5G connections in low frequency bands, new spectrum Will provide in-between performance in a wider area.

On Friday, US Secretary of Transportation Pete Buttigieg and FAA Administrator Steve Dickson wrote a note to AT&T CEO John Stankey and Verizon CEO Hans Vestberg on Friday A letter asking them to postpone their plans to start commercial deployment on January 5.
It is reported that in the reply letter of the two CEOs, the two companies have given up the 30-day delay request and agreed to reduce the power of the signal. They plan to start using C-band to expand their 5G services, but promised not to deploy them in certain airports within six months. They said similar systems are already in place in France. However, this promise depends on the condition that the Federal Aviation Administration and the aviation industry promise to do the same without increasing their dissatisfaction.
US Federal Communications Commission member Mike O’reilly posted this letter on Twitter ,He said, "We can surf the Internet safely and fly safely. Reasonable people should accept the wireless industry in the United States, and there should not be more C-band restrictions than France." According to the FAA, the focus of contention is the guidance of aircraft. The landing system "may be restricted because of concerns that 5G signals may interfere with the accuracy of the aircraft's radio altimeter, and there are no other appropriate mitigation measures." C-band 5G and these radio altimeters do not work in the same band, but the bands are very close, so there is a danger.
It is reported that on behalf of American Airlines, JetBlue Airways, Delta Air Lines, FedEx, and United Parcel, the American Air Trade Group threatened that if the Federal Aviation Administration does not deploy 5G Take action and they will file a lawsuit on Monday. So far, the FAA’s response to this letter is: "We are reviewing the wireless company’s latest letter on how to reduce 5G C-band transmission interference. American Airlines security standards will guide our next steps."
