 What is WIFI? How does WIFI work?

Digital Ritesh

Hello, Dear Friends, I hope you are doing well in your life.

Today, I am here with the promising topic that we use in our day-to-day life. but, we don't know much about it...

The WIFI... we use it every day but, we don't know exactly, how do WIFI works? or What exactly WIFI is? When was WIFI invented? for these many questions I'm writing this article... Let's Start,

The Internet was created through the network. In the past, cable was the only way to send information through digital channels.  Yes, At that time it was the only possible way to get an internet connection through cable.

But, after that, some scientists of technology have created wireless  technology, which has the name WiFi. Today, everyone has access to wireless technology . The new generation of young people would have been connected to the Internet with wireless technology.

What is WIFI?

WIFI is the short form of Wireless Fidelity. And WiFi is also known as WLAN- (Wireless Local Area Network). It is a popular wireless networking technology. It is such an important technology, through which today we are getting high e-speed internet and network connection. WiFi works through radio waves.

To put it simply, WiFi is the technology that allows you wireless access to high-speed Internet from your smartphone, computer, or laptop which Provides this facility. Nowadays, many people have an internet connection via WiFi.

Many electronic devices nowadays include smartphones, laptops, computers, and printers. All of these have a useful chip of wifi. This allows many of us to connect to this wireless router and have the Internet.

Once WiFi is turned on, it connects to a wireless router so that you can use the Internet. But the router needs to use a DSL Modem to stay connected to the Internet. If not, you will not be able to access the Internet.

Who has invented WIFI?

Wi-Fi was invented by John de Sullivan and John Dean in 1991.

Wi-Fi was born in 1985. When the United States FCC announced that the wireless frequencies were 900 MHz, 2.4 GHz, and 5.8 GHz. At that time, anyone could use it without a license. Since then, its history and use of WIFI began.

How does WIFI work?

We all have learned about radiowaves, microwaves, Magnetic Waves, and Infrared light in our studies.

in that context WIFI, do uses radio waves as well as microwaves to send and receive signals of data packets. which are delivered and received to the WIFI-connected devices. 

The devices and gadgets use binary language to communicate. With the help of RadioWaves and MacroWaves, your data is processed in binary format by processing it on a computer or any other device. That's when WiFi works to send it.

In a simple way, If you throw a stone in a pond, the waves form in that pond. and that waves go around till the energy of waves lasts. That is how WIFI creates waves and shares data packets to the devices in the range.

WIFI does have some standards as they create waves in the environment. to keep human being safe, the standards are formed.  those are,

IEEE 802.11a
IEEE 802.11b
IEEE 802.11g
IEEE 802.11n
IEEE 802.11ac

Wifi Speed

The speed of the internet in a Wi-Fi network is much higher than the speed of a mobile network. a simple WiFi router speed can range from 1mbps to 100mbps.
