[Introduction]:Les modules sans fil IoT de la série E51 sont des modules Wi-Sun conçus pour la transmission longue distance et faible consommation. Ils utilisent la puce EFR32FG25 et prennent en charge la technologie de modulation OFDM (Orthogonal Frequency Division Multiplexing) introduite dans les réseaux Wi-SUN (FAN), capables de prendre en charge des milliers de nœuds. Ils prennent en charge le développement utilisateur et sont largement utilisés dans le secteur de l'IoT.
