Based on an October U.S. report referring to the 3.7-3.9 GHz band used by 5G, the French Civil Aviation Authority (DGAC) is concerned that the first 5G antennas could disrupt guidance systems inside aircraft. Indeed, this would create a "major risk" for aircraft radio altimeters that also rely on these frequencies. This system is the only device on board aircraft to be able to measure their distance from the ground or other obstacles. Philippe Barnola, Deputy Director at the DGAC, specifies that "Complementary technical analyses are underway to ensure the compatibility of these 5G stations with the needs of civil aviation".

And this is particularly disturbing for operators, who explain that they were informed of the problem once the frequencies were paid for. Now they fear delays in the deployment of 5G.

While operators will initially focus on city centers, they fear that they will not be able to cover more or less wide areas around airports in the future. And this could concern cities in some cases, such as those around Roissy or Orly airports.

 

The operators have therefore decided to write to the Secretary of State for Digital and Electronic Communications. For its part, SFR is threatening not to pay the first installment it owes the State for frequencies. While Bouygues Telecom wants to be compensated "in proportion to these new constraints".

In the office of the Secretary of State, they want to reassure themselves: "In Germany everything is going well, there is no reason why it should be any different in France". The protection zones around airports will be adapted for 5G, for example. Work has also been launched at the European level.

The same applies to the National Frequency Agency (ANFR). "In the end, there will be a delay of a few weeks or even months on a limited number of antennas near airports [...] There will be no sustainable exclusion zones. French airports have 2G, 3G and 4G. They will also have 5G."
