Assessing 5G Radar Altimeter Interference Download PDF ... In January 2022, the deployment of 5G service using C-band spectrum around airports in the US was delayed due to concerns about interference of base station emissions with radar altimeters on commercial aircraft. Restrictions which prohibited or limited 5G emissions near airports were voluntarily honored until early July 2022. To allow more time to complete the task of retrofitting the entire commercial airline fleet with upgraded radio frequency filters on altimeters, the FAA...
