What is WiFi ?

The term WiFi stands for Wireless Fidelity. It is a technology that let devices connect to the internet and communicate with each other wirelessly.

How WiFi Works ?

The ISP (Internet Service Provider) – like Airtel, Jio etc. Sends internet to your home through Optical Fiber Cable or Copper Cable.

We usually uses a device which is sometime know as a router (with in-built modem). Its job is to receive the internet signals from ISP, then converts that signal data your devices can use and finally broadcast that data wirelessly using WiFi technology.
