CTOnews.com January 11, the Federal Aviation Administration (FAA) has been worried since 2015 that signals from 5G base stations may interfere with aircraft altimeters. However, this problem has not been properly resolved, and FAA decided to give airlines nearly a year to postpone the relevant aircraft rectification plan until February 2024.

CTOnews.com small class: due to the popularity of cable and fiber optic TV services, satellite TV services have been basically withdrawn from the American stage. This means that FAA can release the spectrum of satellite TV services for other purposes.

The Federal Communications Commission (FCC) determines the use of these radio frequencies. It decides that these frequencies are suitable for 5G use and auctions the right to use these frequencies. Verizon and AT&T together paid $68 million for what was then known as the 5G C-band rights.

However, after the auction, another US agency, the Federal Aviation Administration (FAA), jumped out and said that the 5G C-band would interfere with the radio altimeter, which could threaten the take-off and landing of existing flights.

The United States currently imposes temporary 5G C-band restrictions on 50 major airports and requires the aviation industry to inspect their old aircraft and update radio altimeters as needed by July 2023. Now FAA has postponed this time again, pushing the deadline to February 2024.

The airline industry argued last October that temporary restrictions would do no harm to anyone and that the cost of solving the problem was high, so why not make power restrictions permanent? However, the FAA rejected this and gave airlines more time instead.

Foreign science and technology media ArsTechnica reported that:

Today, the FAA proposed a February 1, 2024 deadline to replace or modify the fault altimeter used to measure altitude.

The FAA said it estimated that of the 7993 aircraft registered in the US, about 180 would need to replace radio altimeters and 820 would need additional radio altimeter filters to meet the proposed changes. The total compliance cost is estimated at $26 million.
