主流2.4G频段WiFi对比

文章目录 : 技术相关

无线局域网(WLAN)通信标准标准经历了802.11a, 802.11b, 802.11g到如今主流的802.11n以及802.11ac.

802.11b 11Mbps
802.11 Super b 22Mbps
802.11g/802.11a 54Mbps
802.11 Super G 108Mbps
802.11 High Speed-G 125Mbps
802.11n 150Mbps
802.11n 300Mbps
802.11n 450Mbps

450Mbps是目前2.4Ghz频段速度最快的无线LAN。相比300Mbps无线产品,450Mbps传输更高效流畅,可以维持更高的无线带宽,提供更好的无线连接稳定性和更广覆盖范围。

真正的450M无线应该使用三天线。802.11N协议下150M是一个数据流(Stream), 300M为两个数据流,450M为三个数据流。一根天线收发一个数据流,故300M无线实际上2条天线就足够了。
