U.S. telecom companies and airlines have been fighting for weeks over the potential impact of 5G wireless services on aircraft, in stark contrast to the rollout of new-generation services elsewhere, which has broadly gone ahead without airing new safety concerns.
The U.S. auctioned mid-range 5G bandwidth to mobile phone companies in early 2021 in the 3.7-3.98 GHz range on the spectrum, known as C-Band, for about $80 billion.
The companies have faced pressure from the White House, airlines and aviation unions to delay the deployment amid concerns about potential interference of 5G with sensitive aircraft electronics like radio altimeters.Radio altimeters help to minimize the risk of accidents or collisions by giving an accurate reading of the proximity to the ground. The readouts are also used to facilitate automated landings and to help detect dangerous currents called windshear.
The European Union Aviation Safety Agency , which oversees 31 states, said on Dec. 17 the latest discussion was specific to U.S. airspace. "At this stage, no risk of unsafe interference has been identified in Europe," it said. Currently, 5G mobile communication wireless stations are in operation near airports, but there have been no reports of problems.
