Mobile operators AT&T and Verizon on Wednesday proposed limits for their 5G network for the first half of 2022 in an attempt to launch their services while addressing regulatory concerns about potential flight safety disruptions, The Wall Street Journal reported.
The Journal, which obtained a copy of a letter sent by both operators to the chairman of the Federal Communications Commission Jessica RosenworcelJessica RosenworcelHillicon Valley – Presented by Ericsson – House passes Biden plan with 0M for cyber FCC votes to let people send text messages to 988 to reach suicide prevention hotline Hillicon Valley – TikTok, Snapchat tries to distance itself from Facebook MORE on Wednesday, reported that the companies proposed reducing or limiting the strength of their 5G services across the country, especially near helipads and airports.
“This is an important and encouraging step, and we are committed to continuing constructive dialogue with all stakeholders. We look forward to considering the AT&T and Verizon proposal,” the Federal Aviation Administration (FAA) said in a statement. “The FAA believes that aviation and 5G C-band wireless services can coexist safely.”
The proposal represented “one of the most comprehensive efforts in the world to secure aviation technologies,” said a spokesman for the FCC, according to the Journal.
At the heart of the problem is how frequencies from 5G can affect a system used to calculate the distance between the ground and the aircraft, which is measured by radar altimeters, according to the Journal.
Some radar altimeters may be sensitive and capable of capturing 5G transmissions, although mobile phone operators claim that 5G transmissions are lower than those detected by altimeters. The mobile operator proposed the borders as a way to give the government time to look at the problem.
Although the operators said that the limits would not have a significant impact on the speed of the services they provide to customers, The Journal noted that the proposal is significant because the companies have spent billions on 5G spectrum licenses.
The Hill has contacted AT&T, Verizon and the FCC for comment.
