What is Wi-Fi? (What is WiFi in Hindi)

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

WiFi is simply the 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.

An adapter is created as a hotspot for a WiFi connection, which is usually a wireless router and the rest of the devices such as computers, laptops, mobiles, games councils are connected for internet access.

Wi-Fi is the name of a popular wireless networking technology that uses radio signals to provide high-speed Internet and network connections.

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

Whose words are derived from the words Wireless and Fi IEEE 802.11x. Wi-Fi means IEE 802.11x.

Through this we can connect to the Internet to a limited space. Not only the Internet, nowadays people also transmit data wirelessly through it. For example the use of Share it, Xender.

WiFi is a wireless networking technology standard with multiple versions. Here we tell you about the versions of WiFi.

All versions of WiFi are also given a name with a code name such as 802.11a is called WiFi 1 and 802.11b is called WiFi 2.

  • WiFi 1: 802.11a (1999)
  • WiFi 2: 802.11b (1999)
  • WiFi 3: 802.11g (2003)
  • WiFi 4: 802.11n (2009)

  • WiFi 6:802.11ax (2019)

So far 5 versions of wifi have arrived, the 6th is yet to come, which will come in 2019 this year. Here is the information about WiFi 6,

  • What is wifi 6 and how fast is its speed?

How does WiFi work?

How Does WiFi Technology Work? I tell you the easiest way to understand this. Take for example the wifi at Gadaria office.

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

It has cable from outside internet connection and it provides internet connection via wireless single to all devices around it like laptop, mobile, tablet and PC.

This happens with broadband routers. Now-a-days hotspots are equipped with a device that inputs and experts in Internet data only through a wireless single.

The result is always the same. No matter how the WiFi is being used and what its connection source is.

Nowadays smart phones also have the option of hotspot with Wi-Fi service. That is, you can not only use any other wifi network but can also provide internet connection to many other devices from the hotspot by using it as your phone router.

WiFi features (Wi-Fi features in Hindi)

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

1. Efficiency

Mainly we use Cellular Network for Internet in our mobile. Because its area is more than wifi.

But you will not know that when you use the cellular network in a moving train, train, you keep connecting to different networks again and again.

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

Because Wi-Fi uses Radio Waves for internet and for this you will need a router. This means that it makes little difference to your mobile battery charge.

2. Speed

You will know about the speed of WiFi. WiFi network speeds are much higher than mobile networks. Perhaps you have done this check as well.

For example, if you are doing live streaming with WiFi, you get 1mbps to 100mbps speed, while mobile only keeps loading.

3. Cost

WiFi price is very low compared to mobile data. You will also remember 1GB of internet data was available for around ₹ 100 at a time. However, now the data prices have come down after the arrival of Jio.

Due to the low price, people use WiFi connection for home and office. Otherwise, if the mobile data is used as much as WiFi, then your bill will be 50 times more.

There is so much Internet network provider company, no one can offer such a cheap plan if you reduce their plan to less than WiFi.

4. No Limit

Mobile data has a limit. WiFi but in the network you get more than 50GB of data everyday. Meaning you can use internet as much as you want.

WiFi का इतिहास (History of WiFi in Hindi)

WiFi was born in 1985 when a decision by the US Federal Communications Commission issued an ISM band for unlicensed use.

But WiFi for consumers was first released in 1997., when a committee called 802.11 was formed, known as IEEE 802.11.

At that time the data transfer speed of 802.11 standard was around 2 megabits per second. Then 802.11a was published in 1999.

Its speed was about 54 MBPS. It was followed by 802.11b in 1999, 802.11g in 2003, 802.11n in 2009 and 802.11ac in 2014.

And now the 802.11ax standard is going to come in 2019.

In conclusion,

In this article, we go into detail about what is WiFi, types of WiFi, features of WiFi, advantages and disadvantages of WiFi, and the history of WiFi.
