[Introduction]:E51-470NW16S est un module matériel SoC de transmission longue distance et faible consommation. Le module utilise les puces de la série EFR32FG25 de SiliconLabs, qui peuvent réaliser une diffusion sans fil jusqu'à 0,3 à 2,5 kilomètres avec une perte de données minimale dans les environnements de canyons urbains denses. Il prend également en charge l'introduction de la technologie de modulation de multiplexage par répartition orthogonale de la fréquence (OFDM) dans le réseau de champ Wi-SUN (FAN), qui peut atteindre une bande passante de données élevée allant jusqu'à 3,6 Mbps. Il permet les réseaux à grande échelle requis pour des applications telles que les villes intelligentes et les services publics intelligents, où il peut y avoir des milliers de nœuds. Il a de petites dimensions, des ressources d'interface riches, prend en charge le développement secondaire par les utilisateurs et peut être largement utilisé dans l'industrie de l'Internet des objets.
