What is WiFi? and How does WiFi work?

Today in this post, we will share with you the information about WiFi, I hope you will like all our posts, and we hope that you continue to like all our posts.

What is WiFi? 

Today WiFi is being used everywhere, whether at home, in the office or the bank, most of our work is done through the Internet, nowadays every electronic device you will get Wi-Fi in Computer, Laptop. , Mobile, etc. Device.

We also speak WiFi by this name, It is a local area wireless technology.

This is a technique in which WiFi helps in transferring data from electronic devices and connecting to the Internet using ISM radio bands.

This technology comes under the local area network, which means that its range is limited to a low area.

WiFi helps computers and other devices communicate with the help of a wireless network.

Through this technology, we can connect mobile smartphones, tabs, desktops with wifi dongles, and laptops to the Internet in a limited area.

In this way, we do not need any internet broadband nor any internet connection with cable connectivity.

How does it work?

If you ever go to the airport, coffee shop, railway station, then you are definitely in the wifi zone at that time.

There are many cities where the government has set up a wifi zone where people can go and use the internet for free but have we tried to know how this technology works.

Any wireless network uses radio waves as do mobiles, televisions, and radios.

Understand that whenever there is wireless communication it is always two-way radio communication.

Let us now see how this happens.

The wireless adapter of our laptop converts the data into radio waves and transmits it using the antenna.

The wireless router receives the signal and decodes it. The router sends information through the physical wired ethernet connection to the Internet.

The same process also works in reverse, in which the router receives information from the internet.

It then converts it into a radio signal and sends it to the laptop's wireless adapter.

Radio waves in its network work in the same way as radio waves in the walkie-talkie and cell phone.

The Wifi chip of our mobile and other devices can transmit and receive radio waves. And these chips can convert radio waves into 1 and 0, then 1 and 0 back into radio waves.
