Les fr\u00e9quences hautes permettent un plus grand d\u00e9bit sur des distances plus courtes.<\/p>\n

2 appareils proches communiquant sur la m\u00eame fr\u00e9quence peuvent se brouiller mutuellement et c’est la raison des bandes licenci\u00e9es dont les op\u00e9rateurs t\u00e9l\u00e9phoniques<\/p>\n

Pour choisir quel mat\u00e9riel de communication utiliser, il faut d\u00e9terminer le d\u00e9bit, la quantit\u00e9 de donn\u00e9es, la port\u00e9e, l’autonomie \u00e9nerg\u00e9tique mais aussi le recyclage d’un \u00e9l\u00e9ment inutilis\u00e9 en stock pour \u00e9viter un achat.<\/p>\n

il y a un lien entre d\u00e9bit et port\u00e9e:<\/p>\n
