LoRaWANTM
Classificação dos END-DEVICES
• Cada END-DEVICE se comporta de forma diferente no LoRaWANTM dependendo da
Classe a que pertence. As Classes são estabelecidas em função do grau de otimização
funcional do END-DEVICE:
• CLASSE A
• Baixo Consumo
• Alimentado por Bateria
• Alta latência no envio / recebimento de dados
• CLASSE B
• Médio consumo
• Baixa latência no envio / recebimento de dados
• CLASSE C
• Alto consumo
• Sem latência no envio / recebimento de dados
