What is WiFi and how does it work ?

If you want to know about Wifi, then stay on this post as usual. Today we will give you information about what is WiFi and other WiFi.

You may all know about WiFi but do you also know what is WiFi ? How many types are there? And how to use it?

Do you know what is the history of this Wi-Fi Technology. However, it has been many years since Internet came into the world. But do you know it was very difficult to take its connection at that time.

Internet is born through the network itself. In the time before the network, information was sent through cable only. At that time Conection of Internet was used only.

Due to new changes in the network daily, Computer Scientist finally created wireless technology in the name of wifi.

What is Wi-Fi ?

Wifi stands for “Wireless Fidelity“, a popular network technology. This is a technology through which we are using the Internet.

If we understand in easy language, then Wifi is a Technolgy through which we get the facility of Internet without any wire in Computer, Phone, Laptop.

Through this technology, we can connect to the Internet at any place or place. In this time, every person is connected to the Internet at any place.

Through Wifi technology we can also send DATA from one place to another without wire.

Full form of  WiFi ?

Invention of WiFi –

Wi-Fi was invented by John Dene and John Sullivan in the year 1991.

History of wifi

Wi-Fi was introduced in 1985. According to the United States FCC declaration, any person can use wireless frequency without a license.

This technology failed to solve the problems of interference. Because at that time radio was used before mobile due to which the signal was greatly affected.

At the same time a new technology was invented called WLAN (Wireless Local Area Network). In which there was a lot of technology problem. Many problems were encountered in connecting devices in this WLAN.

In 1988, the standard 802.11 DATA transfer speed was about 2 mega bits per second. The 802.11 DATA standard was published in 1999. At that time his transfer speed was 54 Mehabits per second.

After this time, its next version was published, which was named 802.11B. This technology was launched by WiFi. The network range of this version was also good and the version was also cheap.

When 802.11B became popular in some time, its spread in wireless technology was greatly increased. After this, 6 companies together formed the WECA (Wireless Internet Compatibility) Alliance.

Wifi Standard –

1. IEEE 802.11A:

This standard was created by IEEE in the year 1999, whose frequency worked at a frequency of 5 Ghz at a speed of 11 Mbps.

2. IEEE 802.11B:

This design was made for domestic use in 1999, with a frequency of 5Ghz operating at a speed of 11Mbps.

3. IEEE 802.11G:

This standard was made by 802.11B and 802.11B together in 2003, whose frequency worked at a frequency of 5Ghz at a speed of 11Mbps.

4. IEEE 802.11N:

This standard was created in the year 2009 to work on recurring routers, with a frequency of 54 Mbps at 2.4Ghz to 5 Ghz.

5. IEEE 802.11 AC:

This standard was created in the year 2009, whose frequency worked at 5Ghz with a speed of 13 Gbps.

WiFi is a standard. We connect the computer to the network through standred. All the devices of this time like- laptop, phone and computer have a Wifi chip.

Through which we use the network to connect all these Divaes with wireless Router.

Wifi features –

We have many ways through which we can use the Internet.

1. Efficiency:

Unless a technology is not fully functional in any task, then we do not call it efficient. In today’s time, everyone is using cellular network for Internet because its area is more.

When we connect to the network in mobile and the use of Imternet in the vehicle, our mobile battery gets exhausted.

Radio Waves is used for network in Wifi. In this we need a device router for Wi-Fi so that it provides more net service at higher speeds.

2. Accessibility:

Data plans of all network companies are different. If we talk about mobile, then the data is available only in a few Gb. If we talk about the router, then we can get more than 50 GB of data in it.

3. Speed:

If we talk about Mobile net and Router net speed in terms of network speed then the speed of router is high.

In normal work, the speed of the mobile net is correct, but nothing is faster than videos and games with high load.

4. Cost:

The mobile bill cost of the present time has increased more than before. Earlier people used to use the network thoughtfully. But now people use Free DATA.

If you use a wifi network, then you will get a good data offer from Mobile in a low price.

How does WiFi technology work ?

At this time everyone is using wifi to get more net speed. But do you know how this technology works. If you do not know, then know now.

The Wifi device creates a Wi-Fi network that we call Router. It works by providing or receiving information through the Divaes brandband connection.

Wifi Router converts all information into Radio waves. Through this device, the waves propagate around, creating an area of ​​wireless signal that we know as WiFi John.

A small area of ​​Wifi takes the form of WLAN (wireless local area network). Computer, laptop, mobile all have WiFi technology through which we can receive Wi-Fi signal.

We can use Wifi Router to get good network speed in a home.

what have you learned ?

In this post we have explained what is wifi? You must have known about WiFi in detail.

We hope that by reading this post you have understood the complete information about wifi. Now you will not have any problem in using wifi and you will be able to use wifi easily.

You have an expectation that you can share this post with your friend, facebook, group and all other friends and social media and reach them, so that they too can get information about WiFi .
