What is Wifi, and what is the history of Wifi technology

Do you know what is WiFi is and what is the history of this technology Wifi? By the way, it has been many years since the Internet, but do you know how easy it was to get Internet Connection earlier.

The Internet was born from Network. Earlier, cables were the only way to send information in any digital way. Internet Connection was taken from Cables itself. But you will know that we as humans always like to relax and work without any hassle. I mean how could the Internet work without Cables.

Due to day to day changes, Computer Scientist finally created an AC Wire Less Technology called WiFi. Nowadays everyone is fully aware of this wireless technology. New generation youth are connected to the Internet through this wireless technology. So let’s know in detail what Wi-Fi is

What is Wifi –

The full name of WiFi is Wireless Fidelity. It is a popular Wireless Networking Technology. There is an AC technology, through which we are using the Internet and Network Connection today.

Now understand in your easy language, this is the technology through which we are getting the facility of the Internet in our smartphones, computers, laptops in a wireless way.

Through this, we and you can connect to the Internet within the confined space. Nowadays, everyone has Internet access only through WiFi and along with it, wirelessly transmit data as you do with Share it and Xender. WiFi signals have emerged from the wireless and Hi-Fi Sabbath.

Standard Name of Wifi –

Below is an example of WiFi Standard, which will be understood when you discuss the history further.

  1. IEEE 802.11a: – It was built in the year 1999 by IEEE, which works at 54 Gbps speed up to 115 fit at 5 GHz.
  2. IEEE 802.11b: – It was made for domestic use in 1999, which worked up to 115 fits at 11 Mbps speed at 5 GHz recurring.
  3. IEEE 802.11g: – It was built in the year 2003 by combining 802.11a and 802.11b, which worked at 54 Gbps speed up to 125 fits at 2.4 GHz.
  4. IEEE 802.11n: – It was built in the year 2009 to work on both 2.4 GHz and 5 GHz recurring routers. Its data sending speed worked up to 54 Mbps and 230 fits.
  5. IEEE 802.11ac: – It was built in the year 2009, which worked up to 115 fit at a speed of 1.3 Gbps on 5 GHz recurring.

WiFi is a standard. Following the standard we connect computers to the wireless network. As of now, there are as many Smartphone, Laptop, Printer and Computer. All of them have a WiFi chip. Through which we and you connect to Wireless Router and use the Internet.

Once wifi is enabled, once the wireless Router is connected then you can access the internet. But Router also uses DSL and Cable Modem to stay connected to the Internet. Otherwise, Internet Access is not there.

WiFi is similar to Hi-Fi, whose full form is High Fidelity.

The full form of WiFi is not wireless Fidelity, it is just a name. Selected by the WiFi Alliance. It is also known as WLAN.

It uses Technology Radio Waves. While travelling, you use the Internet. Let us now know how Wifi Technology works.

Who invented WiFi?

Wi-Fi was invented by John O’Sullivan and John Deane in 1991.

History of WiFi –

WiFi was born in 1985. When the United States FCC announced that anyone can use Wireless Frequency 900MHZ, 2.4 GHz and 5.8 GHz without License. Then its history was started.

Sayed you would not know these bands were used in domestic appliances like Microwave. Therefore it was believed that they have no use. Especially there is no use in communication. Therefore, to make this band usable, the FCC made it mandatory to use it. Named Spread Spectrum Technology.

The license of Spread spectrum technology was taken in 1941. George Antheil and Actor Hedy Lamarr were to take the license. This was the technology through which signals were sent with multiple frequencies. Nothing should happen with this change, but after this technology, there was a lot of improvement in wireless signals.

This technology failed to solve Interference Problems. Because at that time there was already Radio Install in Mobiles. Due to which the quality of Signals was greatly affected.

At the same time, technology was emerging, named WLAN (Wireless Local Area Network), which had a lot of technical problems. As such, there was no standard of WLAN. Many problems had to be faced in connecting devices of different companies.

In 1988, the then NCR Corporation required a wireless Cash Register. That is why he, with the cooperation of Victor Hayes and Bruce Tuch, went on to make the Institute of Electrical and Electronics Engineers (IEEE) a standard. In 1997, the standard was fixed and the name which was quite attractive was “802.11”. It was published in 1997.

At that time the speed of DATA Transfer in 802.11 Standard was around 2 megabits Per Second. In 1999, 802.11a was published. Whose speed was around 54 Megabits Per Second. It was quite expensive, so its next version was published, which was named 802.11b, it was launched by WiFi Technology, this version was cheaper and the range of this network was also much higher.

802.11b In a very short time, due to being popular, there was a kind of fence of Wireless Technology. It had established its position in the hardware market very fast. Due to the range and compatibility it was quite famous.

For this reason, 6 companies got together and formed a Wireless Ethernet Compatibility Alliance, or WECA. Through which it was tested whether there is WiFi Compatibility.

In 2002, he derived the words Wi-Fi, Wireless and, a word HiFi. The name of which came to be known after a few years from the Wi-Fi Alliance. Now you must understand what is the history of WiFi.

How Wifi Technology Works –

Nowadays everyone is using WiFi. Whether it is in office or at home or in the Hostel, but no one knows how this technology works. First of all, we need an Electronics Device to use this technology.

Which is called Wireless Transmitter / Hub / Router. This device creates a WiFi network. This Wireless Device (Router), Receives Information through Broadband Connection. Now there are some components inside it.

Which converts this information into Radio Waves. This device emits these Converted Waves outside. A small area of ​​Wireless Signals is formed through this process. Which we call the WiFi zone.

This small area takes the form of a WLAN (Wireless Local Area Network). There are all the devices in this small area like Smartphone, Laptop, Printer if all these devices have a built-in Wireless Adapter. With the help of which one can easily get WiFi Signal.

Remember one thing if a mobile phone is connected to WiFi. Understand that the device has a wireless adapter. Due to not being strong Radio Signals, the distance of this network remains limited. Like inside and around a house, to the side of the road. Meaning its range is from 10 to 20 Meter.

Radio Waves can easily go beyond the wall. For this reason, the facility of the Internet is also available in nearby rooms. However, a wireless router is enough for a house. The more Router you go to the Internet, the faster the network will run, the stronger it will be.

When you send some information (Text, Image, Audio, Video) back to the Wireless Transmitter / Router, the same process will run opposite. As you are connected to WiFi, I mean you’re mobile. EX- You have sent text messages to your friend.

It converts to Radio Waves before exiting Message Mobile and after reaching the signal to Transmitter / Router. Transmitter / Router text is converted into signal and transmits to Broadband and in that the address of Receiver is there. You must have known, this is how WiFi works.

Important Information – There are some devices like Mobile, Laptop, and Tablet in which the Wireless Adapter is already inside. This is the reason why most smartphones get Internet facility through WiFi. There are some such as Desktop does not have wireless Adapter in them.

That is why they have to buy a wireless card or Adapter. Which is then inserted into the USB port of the desktop. Which we can also access in Desktop.

Features of Wifi –

We also have many other routes through which we can use the Internet, but the question is whether there are such features for which this technology is special, so let’s know what is special about friends.

1. Efficiency :

When technology is not proficient in anything, we cannot call it efficient. Everyone nowadays uses cellular networks for the Internet. But you do not know that the area of ​​the cellular networks is more.

But when you live in a moving vehicle, then you use the Internet, but you are often connected to different networks. This is why the energy of your mobile is more exhausted. Now energy can be called battery or charge.

But if we talk about WiFi then it uses Radio Waves. The electronics device you need for this is a Router. You can use the Router for less distance and offers a lot of high-speed Net service. In this, the charge of your smartphone is also less.

2. Accessibility:

All the Network Provider Company. Compare them with a cheaper plan that no one else can give you. Whatever data remains in the mobile plan is in a few GB. If we talk WiFi, then you can get a 50 GB plan in it and more.

You do not need to spend as much as DATA in it. But the plans of companies like Sim like Airtel, Reliance jio, Vodafone are limited.

If you use more than the limit in the mobile network, then the money is cut from the main balance. On mobile, you have to think every time which video to watch and which one to watch. Only you will concentrate on data saving. Therefore, wifi is the best in terms of Net access and data.

3. Speed :

If we compare the speed of Internet in a WiFi network to Mobile Network Speed, then the speed of Wi-Fi is much higher. In the mobile network, if you are reading some mail and if you are reading an online book then by then the speed of the mobile is quite right.

When talking, there is nothing faster than Wi-Fi in video and audio downloading.

Live streaming if you are doing it from your mobile. Just waiting for loading in mobile. No one can compete with WIFI in speed. Speeds range from about 1mbps to 100 Mbps.

4. Cost:

Now Jio is 4G so people do not know how much is the bill. But the price of mobile data was one year ago. Before recharging, we had to think about 100 times. So far, you have used the free data of Jio.

If it is calculated, then it is common to have a bill of 1 lakh. If you take a WiFi connection at home, then you will get a very cheap plan at a low cost.

Whose family you can not use alone. Due to being cheap, in Hostel, College, School, Office Vagera, use this cheap Internet Connection. You can also minimize the bills of your mobiles through online video calling and voice calling.

Therefore it is cost-effective and money-saving. Let us now know about its advantages and disadvantages.

Advantages of WiFi –

1. Convenient

This technology is quite user-friendly. You can easily connect any smartphone, tablet and laptop with wifi when it should be in the range of device wifi.

2. Simplicity

It is very easy to use it, just you have to turn on wifi. If there is a password Enter password and connect. Enjoy the Internet.

3. Mobility

Mobility means you can access the Internet from anywhere on the go. Such as Bus, Train, Coffee shop, Super Market where it is Network.

4. Expandability

With a single WiFi device, you can connect many other mobile devices. For example, 5 to 6 mobile devices can connect with a Router. It takes you very little time to do this connection.

5. Efficiency

As you know it is very easy to access WiFi and its range is also fixed. Its speed is in Mbps. That is why it is used in other works. Like file sharing (Text, Audio, Video) like you do in the File Sharing app.

6. Cost control

If a lot of users are already connected to WiFi and you want another device to be connected as well. For this, you do not need to spend anything more and do not need any Cables. Now talk about Broadband Connection, then you need more Cables and Reconfiguration.

7. Standardization

The most important and important advantage is that it is quite standardized. Meaning a WiFi Router can run in all countries of the world.

Disadvantages of WiFi –

1. Performance / Speed

By the way, you will get Gigabit Speed ​​WiFi in the market but till now Gigabit Speed ​​is not available in every location in them. But Gigabit Speed ​​is available in Cables.

2. Connectivity / Reliability

It is a medium dependent network. This means that the strength of the wifi signal decreases after crossing any wall. You know the fixed range of WiFi remains.

3. Distance

You can access WiFi in a fixed location only. The farther you go, the lower the strength of the network will be. Like 10 meters to 20 Meters will have to remain within.

4. Security

Nowadays, anyone can enter your system via WiFi and steal your data. So this is the biggest loss of this technology.

What is Wi-Fi 6 –

Wi-Fi 6 is the next generation standard of WiFi technology. Wi-Fi 6 is also called “AX WiFi” or “802.11ax WiFi”. It has been built by further improving the Mezhuda 802.11ac WiFi standard.

It would not be wrong to call Wi-Fi 6 the fastest WiFi of all time. If you people do not know about the new technology of WiFi, then you should tell people that this is going to bring a big revolution in the world of wireless technology. WiFi 6 is also known as “AX WiFi” and “802.11ax WiFi”.

Also read –

Like I said earlier, it has been made by making necessary improvements in the current 802.11ac WiFi standard. Originally, WiFi 6 was created in response to the increasing number of devices in the world.

Wi-Fi standard Wi-Fi name
802.11n Wi-Fi 4
802.11ac Wi-Fi 5
802.11ax Wi-Fi 6

If, WiFi 6 is an upgrade update for the WiFi router and not an upgrade to the WiFi service in general. For example, if you have a VR device and many smartphone home devices, then the WiFi 6 router can prove to be a very good WiFi router for you.

Why is Wi-Fi 6 designed?

Wi-Fi 6 is designed to improve Wi-Fi speed, to increase efficiency and to reduce congestion (congestion) in scenarios with heavy bandwidth usage.

How fast is wifi 6?

The theoretical speeds of WiFi 6 or 802.11ax are around 10Gbps. At the same time, it also has a very low power consumption with speed.

It has a higher speed because 2.4GHz and 5GHz spectrum bands are combined on it. Where previously both bands in 802.11ac and 802.11n (or Wi-Fi 4) were forced to work separately, but in this new standard both are used together.

MU-MIMO technology will now also be enabled for uplink data with downlink data which is used to support earlier.

After the arrival of WiFi 6, there will be a lot of difference in the world of wireless technology. The world of Internet will change to a great extent.

Conclusion –

I endeavour to always get correct, accurate and complete information from you. Today you learned what is WiFi and what is the history of wifi technology.
