Several Norwegian Government Agencies Cooperate To Test The Impact Of 5G Spectrum On Flight

In the middle of last month, AT&T and Verizon, the two largest telecommunications companies in the United States, announced that they would delay the opening of 5G networks that were originally planned to be near airports, in response to airline concerns that 5G networks could affect flight safety.

Similar discussions have emerged in Europe, where the Norwegian Communications Authority (Nkom) has taken the lead in conducting related 5G tests in cooperation with various government agencies.

Due to reports in the United States that the C-Band 5G network would interfere with the aircraft’s altimeter, the Norwegian Communications Authority had earlier cooperated with the local army, the Army Research Institute, the Air Force, the police helicopter service, the air rescue agency, two telecommunications providers Telenor and Telia, and Yu Kai.

Le Airport conducted actual measurements to try to determine whether the 5G signal would interfere with the radar altimeter. The Norwegian Communications Authority stated that after observation and analysis, no interference was found with the radar altimeter of the helicopter involved in the test.

According to the Norwegian Communications Authority, the 5G spectrum used in Europe and Norway is 3.4GHz to 3.8GHz, which is slightly lower than the 3.7GHz to 3.98GHz used in the United States, while the spectrum used by aircraft flight systems and altimeters is 4.2GHz to 4.4GHz.

The Norwegian Communications Authority emphasized that the survey will help clarify whether the 5G spectrum will affect Norwegian and European aircraft, and the results are also important.
