1.无线保真(Wi-Fi):
Wi-Fi是一种无线联网技术,它允许诸如计算机,移动设备和其他电子设备之类的设备与Internet进行接口。通过使用无线电波来提供无线高速Internet和网络连接。借助无线路由器,可以实现Internet连接。它是基于IEEE 802.11标准的无线网络协议。主要是指无线局域网技术。

2.千兆保真(Gi-Fi):
Gi-Fi或千兆无线是指无线传输系统。 Gi-Fi提供每秒超过十亿位的数据速率。它是Wi-Fi的更快版本。一般来说,如果我们能看到它比WiFi技术快十倍。 Gi-Fi技术是集成在单个芯片上的全球收发器,该芯片使用CMOS工艺在60GHz下运行。 IEEE 802.15.3C标准中定义的Gi-Fi。

Wi-Fi和Gi-Fi之间的区别:

S.No. Wi-Fi Gi-Fi
