WIFI Full Form – Do you know what is WiFi (What is WiFi ) and what is the history of this technology. Although it has been many years since Internet came in the world, but do you know how difficult it was to get Internet Connection earlier.
The Internet was born from the network. Earlier cables were the only way to send any information digitally. Internet connection was taken from cables only. But you must know that we humans always like to work comfortably and without any trouble. I mean how the Internet can work without cables, they used to think that.
Due to day to day change, finally Computer Scientist made an AC Wire Less Technology named WiFi. Nowadays everyone is completely aware of this wireless technology. The youth of the new generation remain connected to the Internet through this wire less technology. So let us know in detail what is Wi-Fi.
WIFI Full Form
The full form of WiFi is Wireless Fidelity.
WI – Wireless
FI – Fidelity
This is a popular Wireless Networking Technology. There is such a technology, through which today we are using Internet and Network Connection.
Now let’s understand in your easy language, this is the technology through which we are getting internet facility in our smart phone, computer, laptop in a wireless way today.
Examples of WiFi Standards are given below, about which you will understand when we discuss about the history further.
History of WIFI
IEEE 802.11a: – was created in the year 1999 by IEEE, which works at 54 Mbps speed up to 115 ft on 5 GHz frequency.
It failed to solve the Technology Interference Problems. Because the mobiles of that time already had Radio installed. Due to which there was a lot of impact in the quality of the signals.
At the same time a technology was emerging which was named WLAN (Wireless Local Area Network) which had many technical faults. Like there was no standard of WLAN. Many difficulties had to be faced in connecting the devices of different companies.
In 1988, the then NCR Corporation needed a wireless cash register. That is why he, with the help of Victor Hayes and Bruce Tuch, tried to make the Institute of Electrical and Electronic Engineers (IEEE) a standard. The standard was ready in 1997 and whose name was quite attractive was the name “802.11”. It was published only in 1997.
At that time the speed of DATA transfer in 802.11 standard was about 2 megabits per second. 802.11a was published in 1999. Whose speed was about 54 Megabits Per Second. It was very expensive, so its next version was published which was named 802.11b, it was started of WiFi technology, this version was cheap and the range of this network was also very high.
Due to this being popular within a very short time, the fence of wireless technology had come in a way. Very fast it had established its position in the hardware market. Due to the range and compatibility, it was quite expensive.
In 2002, he introduced the term Wi-Fi, and Wireless, a term derived from HiFi. Whose name came to be known after a few years by the Wi-Fi Alliance. Now you must have understood what is the history of WiFi.
How Wifi Works ?
Nowadays everyone is using WiFi. Whether it is in the office or at home or in the hostel, but no one knows how this technology works. First of all, to use this technology, we need an electronics device.
This device creates 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 out. Through this process, a small wireless signal area is formed. Which we call WiFi zone.
This small area takes the form of a WLAN (wireless local area network). All the devices in this small area like Smartphone, Laptop, Printer if all these devices have built-in Wireless Adapter. With the help of which you can easily get WiFi Signal.
Remember one thing if a mobile phone is connected to WiFi. To understand that there is a wireless adapter in that device. Due to not being strong Radio Signals, the distance of this network remains limited. Like inside a house and in the adjoining house, till the side of the road. Meaning its range remains from 10 to 20 meters.
Radio Waves can easily travel across the wall. For this reason, internet facility is also available in nearby rooms. However, a wireless router is enough for a house. The more you go to the router, the faster the Internet will run, the stronger the network will be.
When you send some information (Text, Image, Audio, Video) back to the Wireless Transmitter / Router, the same process will run in reverse. As you are connected to WiFi, I mean your Mobile. EX- You have sent a text message to your friend.
This message is converted into Radio Waves before exiting the mobile and after reaching the signal to the Transmitter/Router. The Transmitter/Router converts the text into a signal and transmits it to Broadband and the Receiver’s address remains in it. You must have known, this is how WiFi works.
Important information – There are some devices such as Mobile, Laptop, and Tablet in which the wireless adapter is already inside. For this reason, most of the smartphones get internet facility from WiFi. There are some such as Desktop does not have a wireless adapter in them.
That’s why they have to buy a Wireless Card or Adapter. Which is then put in the USB port of the desktop. Which we can access the Internet even in Desktop.
Features of WIFI
We also have many other ways through which we can use the Internet, but the question is whether it has such features for which this technology is special, so let’s friends know what is the specialty.
When a technology is not proficient in something, we cannot call it efficient. Everyone uses cellular network for internet nowadays. But you do not know that the area of cellular network is more.
But when you live in a moving vehicle, you use the Internet, but you keep connecting to different networks again and again. For this reason, the energy of your mobile is exhausted more. Now energy means battery or can be called 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 short distances and gives a lot of high speed net service. In this the charge of your smartphone is also reduced.
All the network provider companies are there. Compare them, no one else can give you a plan as cheap as WiFi. Whatever data remains in the mobile plan is in a few GB. If we talk about WiFi, then you can get a plan of 50 GB in this and even more.
Spend as much as DATA in this, there is no need for you to be limited. 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 deducted from the main balance. In mobile, you have to think every time which video to watch and which one not to watch. Only you will focus on data saving. That’s why wifi is the best in terms of net access and data.
If we compare the speed of Internet in a WiFi network with Mobile Network Speed, then the speed of this Wi-Fi is very high. In mobile network, if you are reading some mail and if you are reading book book online, then the speed of mobile is quite fine.
When it comes to Video and Audio Downloading, nothing is faster than Wi-Fi.
Live streaming if you are doing from your mobile. Mobile simply has to wait for loading. No one can compete with WIFI in speed. The speed ranges from about 1mbps to 100 mbps.
Now Jio is 4G so people don’t know how much is the bill. But a year ago that was the price of mobile data. Had to think about 100 times before recharge. Till now you have used all the free data of jio.
If it is calculated, then it is common to get 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.
Which you can not use alone but your whole family can use it. Due to being cheap, in Hostel, College, School, Office Vagera, use this cheap Internet Connection. You can also minimize your mobile bills 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
This technology is quite user-friendly. You can easily connect any smart phone, tablet and laptop with wifi when it should be in the range of device wifi.
It is very easy to use it, you just have to turn on wifi. If there is a password. Enter password and connect. Enjoy the Internet.
Mobility means you can access the Internet from anywhere on the go. Like Bus, Train, Coffee shop, Super Market where this network is.
With the same WiFi Device, you can connect many other Mobile Devices. For example, 5 to 6 mobile devices can be connected with a router. It takes you very little time to do this connection.
As you know, accessing WiFi is very easy 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 File Sharing app.
If there are already many users connected to WiFi and you want another device to be connected as well. For this you do not need to spend a lot nor do you need any cables. Now talk about Broadband Connection, then you need more Cables and Reconfiguration.
The most important and important advantage is that it is quite standardized. Meaning a WiFi Router can run in all the countries of the world.
Disadvantages of WiFi
Although you will find 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.
This is a Medium dependent network. This means that the strength of the signals decreases as soon as the wifi signal crosses any wall. You know that WiFi has a fixed range.
You can access WiFi only in a fixed location. The farther you go, the less the strength of the network will be. Like you have to stay within 10 meters to 20 meters.
Nowadays anyone can steal your data by entering any system through WiFi. That’s why this is the biggest disadvantage of this technology.
