亚马逊、苹果与谷歌、三星开源智能家居设备商兼容性FA-20H爱普生晶振Q24FA20H0016600
Zigbee和蓝牙都是不适配IPv6的底层协议,例如ZigBee,它规定了要求的底层协议、专用的网络层/传输层和专用的应用层.所以Matter与Zigbee、蓝牙是互斥的协议,无法共同存在;而与Wi-Fi则是依赖关系.由此可见,Matter是基于传输层之上的应用层协议,爱普生晶振它依赖于以太网、Wi-Fi、Thread等底层协议.应用层为Matter、传输层为TCP/UDP、网络层为IPv6、底层为适配IPv6的协议以太网、Wi-Fi、Thread,等等.智能家居设备商兼容性Matter1.0的诞生2019年12月智能家居开源标准Matter首次由亚马逊、苹果、谷歌、三星Smart Things和Zig Bee联盟联合发起提出.

当时还被称为IP互联家庭项目Project Connected HomeoverIP,简称CHIP.该项目旨在开发、推广一项免除专利费的新连接协议,将Zigbee、Thread、蓝牙和Wi-Fi等不同组件整合到一个总体标准中,以简化智能家居设备商开发成本,石英晶振提高产品之间兼容性.展示了Matter与Zig Bee、蓝牙、Wi-Fi的关系.OSI七层网络模型大家都比较熟悉了,从高到低,依次为:应用层、表示层、会话层、传输层、网络层、数据链路层、物理层.这里简化了一下,将会话层和表示层合并到应用层,数据链路层和物理层合并到底层,形成新的网络模型:应用层、传输层、网络层、底层.
