© 2010 Microchip Technology Incorporated. All Rights Reserved. 1461 ZIG Slide 56 Miwi O MiWi™ Wireless Networking Protocol é um protocolo simples projetado para baixa taxa de dados, pequena distância e para redes de baixo custo. É fundamentalmente baseado no padrão IEEE 802.15.4™ para wireless personal area networks (WPANs) . É uma alternativa de fácil uso para comunicação wireless Tem um custo menor para pequenas redes, com poucos saltos entre os nós.

© 2010 Microchip Technology Incorporated. All Rights Reserved. 1461 ZIG Slide 57 Características Uma rede utilizando o protocolo MiWi é capaz de ter no máximo 1024 dispositivos na rede. Cada coordenador é capaz de ter 127 dispositivos coordenados por ele, e uma rede pode ter o máximo de oito coordenadores. Os pacotes de dados podem ter no máximo quatro hops (pulos) na rede.
