The Internet has just started a few years. Only Cables were the only way to send any information digitally in the past.

But the technology changed day by day and Computer Scientist created a wireless technology through which non-data transfer of data was started.

The name of that technology is WiFi

Today we will learn about this here. So let’s know in detail what WiFi is?

What is Wi-Fi?

WiFi is a technology that provides network connectivity using the radio web. We use the internet through this.

WiFi is the only popular Wireless Networking Technology name. This means that it is a trademark of the WiFi Alliance. It is also called the family of radio technologies.

For a WiFi connection, an adapter is created as a hotspot. Usually, a wireless router and the rest of the devices such as computers, laptops, mobile, game councils are connected to Internet access.

Wi-Fi is the name of an accessible wireless networking technology, which uses radio signals to provide high-speed internet and network connections.

One common assumption is that the full name of WiFi is “Wireless Fidelity”, but this is not true. Wi-Fi is only a trademark phrase, which is used solely for the brand name.

Whose Wi-word Wireless and Fi are derived from the IEEE 802.11x. Wi-Fi stands for IEE 802.11x.

Through this, we can connect to the Internet in a limited space. Not only the Internet but nowadays people also do Wirelessly Data Transmit through it. For example, share it, using Xander.

WiFi is a wireless networking technology standard, which has more than one version. Here we tell you about the versions of WiFi.

All versions of WiFi are given a name along with the code name, such as 802.11a, WiFi 1 and 802.11b are called WiFi 2.

  • WiFi 1: 802.11a (1999)
  • WiFi 2: 802.11b (1999)
  • WiFi 3: 802.11g (2003)
  • WiFi 4: 802.11n (2009)
  • WiFi 5: 802.11ac (2014)
  • WiFi 6:802.11ax (2019)

So far, five versions of WiFi have come 6th is yet to come, which will come in 2019 this year. Information about WiFi 6 is here,

How does WiFi work?

How does WiFi Technology work? I tell you the easiest way to understand this. For example, you take the WiFi of the Crime office.

It contains a device that transmits a wireless single, which is usually a WiFi router or hotspot.

Cable from outside is connected to the internet connection, and it provides all the devices around you, such as laptops, mobile, tablets and PCs, to the Internet via wireless single internet connection.

This happens with a broadband router. Nowadays running hotspots have a device that can input and experience Internet data through a wireless single.

The result is always the same. How WiFi is being used and what is its connection source, it does not make any difference.

Today’s Smart Phone also comes with Hotspot option, Wi-Fi service. That is, you can not only use another WiFi network, but you can provide an internet connection to many other devices from hotspots using your phone router.

WiFi Features

You must know about WiFi features. So that you can use it well. WiFi features are as follows.

1. Efficiency

Mainly we use Cellular Network for Internet in our mobile. Because its area is much higher than WiFi.

But you will not know that when you use a cellular network in a moving train, you often get connected to different systems.

This eliminates more of the energy of mobile. That is, the battery of your mobile is quickly over. But this does not happen with WiFi.

Because Wi-Fi uses the Radio Waves for the Internet and you will need a router for it. This means that you make a minimal difference to your mobile battery charge.

2. Speed

You will know about the speed of WiFi. The rate of the WiFi network is much higher compared to the cellular web. Perhaps you have already checked this.

3. Cost

WiFi Price is much lower than mobile data. You will also remember that at one time, approximately one ₹ 100 internet data was available. However, after the arrival of Jio, data prices have come down.

Because of the low cost, people use WiFi connections for home, office. Otherwise, if you use the mobile data as much as WiFi, your bill will be 50 times more.

So is the internet network provider company, if you do their plans less than WiFi, then WiFi can not offer much cheaper plans.

4. No Limit

There is a limit on mobile data. WiFi but you get more than 50GB of data every day in the network. That means you can use the internet as much as you want.

History of WiFi (History of WiFi )

WiFi was born in 1985 when the US Federal Communications Commission’s decision had issued ISM bands for unauthorised use.

But for WiFi consumers was released for the first time in 1997, when a committee called 802.11 was created, which is known as IEEE 802.11.

At that time, the data transfer speed of 802.11 standards was about two megabits per second. After that, 802.11a was published in 1999.

Its speed was about 54 MBPS. After that, 802.11b in 1999, 802.11g in 2003, 802.11n in 2009 and 802.11ac in 2014.

And now in 2019 802.11x standard is coming.
