为什么1200M的覆盖能力和速度不如450M?

Category : 其他

目前路由器大部分都带802.11n的无线WiFi了。但后期也会往802.11ac双频发展。

1200M为无线双频802.11ac,提供的是300M的2.4G和866M的5G两个频段信号。但是目前大部分智能手机、平板电脑、笔记本的无线网卡及其他设备都只工作在2.4G频段,5G频段基本闲置,所以,实际上只使用了300M的速率,效果不如450M!所以,从目前来讲,无线速率快不快,目前关键看路由器在2.4G频段的表现。

从目前伊林思的路由器来看,主要是802.11n的150Mps速率的WLAN与802.11n的300Mbps的速率,均支持MIMO。

H685系列 150Mbps
H820系列 150Mbps
H700系列 300Mbps
H700系列 300Mbps

伊林思的路由器均为工业级,工业设备使用的WiFi目前一般都没有超过300Mbps,所以伊林思的主要产品里面不带450Mbps的WiFi。然后伊林思的H860系列可以由客户自行配置450Mbps的WiFi甚至是802.11ac双频的WiFi.
