U.S. aviation regulator warns of potential interference from 5G spectrum plan, World News
The Federal Aviation Administration said on Tuesday it had issued a special newsletter alerting manufacturers, operators and pilots that action may be needed to address potential interference with sensitive aircraft electronics caused by the use of the technology 5G telecommunications.
The FAA has discussed with the Federal Communications Commission its aviation safety concerns over plans to begin using additional spectrum for 5G wireless networks from December 5.

The FAA said on Tuesday that operators “should be prepared for the possibility that interference from 5G transmitters and other technologies could cause certain safety equipment to malfunction, requiring them to take mitigating measures that could affect operations. flight”.
According to the bulletin, “there have not yet been any proven reports of harmful interference from wireless broadband operations internationally.”
He also recommends that pilots remind passengers that all portable electronic devices equipped with 5G should be turned off or put into airplane mode during flight.
The FAA warned of the potential for “degradation of the capabilities of security systems and other equipment that depend on radio altimeters, especially during low-altitude operations.”

The FAA said equipment manufacturers should also continue testing to determine the sensitivity of specific radio altimeters to 5G interference and should explore design changes that could mitigate the effects of the interference.
The aviation industry has been alarmed by the proposed use of C-band spectrum for over a year. Network operators are expected to start using spectrum from December 5 in 46 markets.
Deputy FAA Administrator Bradley Mims in a letter first reported by Reuters on Friday said the agency shares “deep concern about the potential impact on aviation safety resulting from interference on the performance of the radar altimeter of 5G network operations in the C band “.
The Federal Communications Commission (FCC) said on Tuesday it was “committed to continuing to work with its federal partners to simultaneously preserve aviation safety and advance the deployment of new technologies.”
The aerospace and airline industry met with the FCC in August, warning that without change “major disruptions in the use of the national airspace system can be expected from the deployment of 5G” and added that the FAA will be forced to “significantly reduce the operational capability of aviation.”
Wireless business group CTIA said on Friday that 5G networks can safely use C-band spectrum “without causing harmful interference to aircraft equipment,” and cited numerous active 5G networks using that band of spectrum in 40 countries.
