La technologie 5G<\/a> est sous les feux de l’Administration F\u00e9d\u00e9rale de l’Aviation aux Etats-Unis<\/strong>. L’autorit\u00e9 en charge de la gestion du transport a\u00e9rien dans le pays vient en effet d’ annoncer mettre en place une nouvelle r\u00e8gle de s\u00e9curit\u00e9. Elle interdit aux pilotes d’utiliser l’atterrissage automatique et autres syst\u00e8mes d’aide en vol \u00e0 basse altitude. Elle estime en effet que les signaux 5G pourraient interf\u00e9rer avec les instruments calculant la distance de l’avion par rapport au sol<\/strong>.<\/p>\n

Des interf\u00e9rences avec certains syst\u00e8mes d’atterrissage ?<\/span><\/h3>\n

Pour la FAA, la 5G interf\u00e9rerait avec les radioaltim\u00e8tres utilis\u00e9s sur des vols avec des conditions de faible visibilit\u00e9<\/strong>. Les radioaltim\u00e8tres permettent dans cette configuration des atterrissages en toute s\u00e9curit\u00e9.<\/p>\n

Mais la FAA estime que la 5G pourrait entra\u00eener des lectures erron\u00e9es des donn\u00e9es<\/strong>, rendant le vol dangereux<\/strong>. La nouvelle technologie affecterait notamment certaines fr\u00e9quences radio. En effet, les ondes utilis\u00e9es par la 5G couvrent une partie du spectre des fr\u00e9quences radio appel\u00e9e bande C<\/strong>. Cette bande est adjacente aux ondes utilis\u00e9es par les radioaltim\u00e8tres pour mesurer l’altitude d’un avion.<\/p>\n

Selon la FAA, la r\u00e8gle concernerait plus de 6 800 avions am\u00e9ricains, plus de 1 800 h\u00e9licopt\u00e8res et des dizaines de fabricants d’avions<\/strong>.<\/p>\n

L’injonction de la FAA<\/a> rev\u00eat un caract\u00e8re d’urgence<\/strong>. \u00ab\u00a0Il existe une condition dangereuse qui exige l’adoption imm\u00e9diate de cet [ordre] sans donner l’occasion au public de faire des commentaires avant l’adoption<\/em>\u00ab\u00a0, a d\u00e9clar\u00e9 l’agence. \u00ab\u00a0La FAA a estim\u00e9 que le risque pour le public en avion justifie de renoncer \u00e0 l’avis et aux commentaires avant l’adoption de cette r\u00e8gle.<\/em>\u00a0\u00bb<\/p>\n

La FAA pr\u00e9voit de publier \u00e9galement une liste d’a\u00e9roports les plus susceptibles d’\u00eatre affect\u00e9s par la technologie 5G<\/strong>. Certains a\u00e9roports pourraient ainsi interdire l’utilisation de la 5G sur leur territoire et les proches environs.<\/p>\n

Contestation des op\u00e9rateurs de la technologie 5G<\/span><\/h3>\n

L’autorit\u00e9 de l’aviation civile indique avoir travaill\u00e9 depuis de nombreux mois avec les op\u00e9rateurs t\u00e9l\u00e9coms impliqu\u00e9s dans la technologie de la 5G. La FAA indique qu’elle travaille en \u00e9troite collaboration avec la Federal Communications Commission<\/strong> et les entreprises de t\u00e9l\u00e9communications sans fil. Elle estime avoir progress\u00e9 vers une mise en \u0153uvre s\u00fbre de l’expansion de la 5G. Selon la FAA, \u00ab\u00a0nous sommes convaincus qu’avec une collaboration continue, nous atteindrons cet objectif commun d’une coexistence en toute s\u00e9curit\u00e9<\/em>\u00ab\u00a0.<\/p>\n

L’inqui\u00e9tude autour de la FAA s’est d\u00e9j\u00e0 traduit par un retard dans la mise en service de la 5G aux Etats-Unis<\/strong>. Pr\u00e9vue originellement le 5 d\u00e9cembre, la 5G deviendra effective le 5 janvier prochain<\/strong> apr\u00e8s que l’industrie ait accept\u00e9 un report.<\/p>\n

L’association repr\u00e9sentant l’industrie du sans fil, la CTIA, s’oppose \u00e0 la d\u00e9cision de la FAA. \u00ab\u00a0Tout retard dans l’activation de cette technologie risque la comp\u00e9titivit\u00e9 de l’Am\u00e9rique. Elle compromet notre capacit\u00e9 \u00e0 assurer le leadership mondial de la 5G<\/em>,\u00a0\u00bb indique l’association.<\/p>\n

Selon la CTIA, le spectre de la bande C repr\u00e9sente d\u00e9j\u00e0 l’\u00e9pine dorsale des r\u00e9seaux 5G dans le monde entier. Pr\u00e8s de 40 pays utilisent ce spectre, dont beaucoup depuis pr\u00e8s de trois ans<\/strong>. Et sans r\u00e9el danger pour l’aviation, estime-t-elle.<\/p>\n","protected":false},"excerpt":{"rendered":"
