Do you know what Wi-Fi is and what the history of this technology is? Although it has been many years since the Internet has come in the world, 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 the Internet could work without Cables.
Due to day to day changes, finally Computer Scientist created an AC Wire Less Technology named Wi-Fi. 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 Wi-Fi
The full name of Wi-Fi is Wireless Fidelity. It is a popular Wireless Networking Technology. AC Technology has, through which we Internet and Network Connection are used to.
Now understand in your easy language, this is the technology through which we are getting the facility of Internet in our smart phones, 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 Wi-Fi and along with it, wirelessly transmit data as you do with Share it and Xender . Wi-Fi signals have emerged from the wireless and Hi-Fi Sabbath.
Under Wi-Fi Standard of Example is given about who will discuss further when history then you will appear in it.
IEEE 802.11a : – was built in the year 1999 by IEEE , which works at 54 Gbps speed up to 115 fit at 5 GHz .
IEEE 802.11b : – It was made for domestic use in 1999 , which worked up to 115 fit at 11 Mbps speed at 5 GHz recurring .
IEEE 802.11g : – was built in the year 2003 by combining 802.11a and 802.11b , which worked at 54 Gbps speed up to 125 fit at 2.4 GHz .
IEEE 802klln : – It is the year 2009 in the 2.4 GHz and 5 GHz both recurring Router ( Dual Band Router) was created to work on. Its data sending speed worked up to 54 Mbps and 230 fit.
IEEE 802.11ac : – It was built in the year 2009 , which worked up to 115 Fits at a speed of 1.3 Gbps on 5 GHz recurring .
Wi-Fi standard (Standard) is. The Standard We Follow the Computers and Wireless network connect. As of now, there are as many Smartphone, Laptop, Printer and Computer. All of them have a Wi-Fi chip. Through which we have Wireless Router to connect to and Internet used to.
Once Wi-Fi is enabled, once wireless Router is connected then you can access internet. But Router also uses DSL and Cable Modem to stay connected to the Internet. Otherwise Internet Access is not there.
Wi-Fi Though Hi-Fi is its resemblance to the Full Form of High Fidelity K the full form of Wi-Fi is not wireless Fidelity, it is just a name. Selected by Wi-Fi Alliance. It is also known as WLAN.
It uses Technology Radio Waves. You use the Internet while walking. Let us now know how Wi-Fi Technology works.
What is the full form of Wi-Fi ?
The full form of Wi-Fi is Wireless Fidelity.
Who invented Wi-Fi?
Wi-Fi (Wi-Fi) invented John O’Sullivan and John Deane of the year 1991 did.
History of Wi-Fi
Wi-Fi was born on 1985. United State FCC when it did Alan Wireless Frequency 900MHZ, 2.4 Ghz and 5.8 Ghz without any of the License for Use can. Then its history was started.
Sayed you would not know these bands were used in home appliances like Microwave. Therefore it was believed that they have no use . Especially Communication none Use no. Therefore, to make this band usable, the FCC made it mandatory to use it. Named Speared Spectrum Technology.
The license of Spread spectrum technology was taken on 1941. License was taking George Antheil and Actor Hedy Lamarr K This was the technology through which signals were sent with multiple frequencies. Does not have anything to do with this change, but at that time this Technology after Wireless signals significantly Improvement saw.
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, a technology was emerging, named WLAN (Wireless Local Area Network ), which had a lot of technical problems. As such there was no standard of WLAN . Different Company ‘s Devices had to face a lot of Presnion add.
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 Electronic 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 itself .
Then 802.11 Standard for DATA Transfer of Speed around 2 megabits Per Second was. In 1999 , 802.11a was published . Whose speed was around 54 Megabits Per Second . It was quite expensive so it Next Version was published called 802.11b it went to be starting with Wi-Fi Technology of , this Version cheap and the Network of Range was also very much.
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 . Whereby this Test was used Computability Wi-Fi or not.
2002 in , she Wi-Fi word , Wireless and , in a word Hi-Fi was taken. 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 Wi-Fi.
How Wi-Fi Technology Works
Nowadays everyone is using Wi-Fi . Whether it is in Office or at home or in Hostel but no one knows how this technology works. First of all we need an Electronics Device to use this technology.
Which Wireless Transmitter / Hub / Router say. These Device Wi-Fi Network to create an It Wireless Device (Router), Broadband connection by Information Receive does. Now there are some components inside it.
This Information to Radio Waves to Convert does. This Device These Converted Waves outside the Emit does. Through this process a little bit Wireless Signals the Area is formed. Which we call Wi-Fi zone .
This small area takes the form of a WLAN (wireless Local Area Network) . Similar small Area for all the Devices such as Smartphone, Laptop, Printer. if all these Devices for in built Wireless Adapter are. With the help of which one can easily get Wi-Fi Signal.
Remember one thing if a mobile phone is connected to Wi-Fi. 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 Internet is also available in nearby rooms. However a wireless router is enough for a house. You as Router have to be Internet too much speed will Network equally Strong will.
When you send some information (Text, Image, Audio, Video) back to the Wireless Transmitter / Router , the same process will run opposite. Like you are connected to Wi-Fi , I mean your mobile. EX- You have sent text messages to your friend.
This Mobile Message before getting out of Radio Waves in Convert the Code and Transmitter / Router to signal reaching. Transmitter / Router text to signal to Convert to Broadband in Transmit turns and the Receiver ‘s Address lives. You must have known, this is how Wi-Fi works.
Features of WI-FI
We also have many other ways that 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.
: When a technology is not proficient in anything, we cannot call it efficient. Everyone nowadays uses cellular network for Internet. But you do not know that the area area of cellular network is more.
But when you’re in a moving vehicle to Internet to use then but frequently different Network are added. This is why the energy of your mobile is more exhausted. Now energy means battery or charge can say.
But if we talk about Wi-Fi , it uses Radio Waves . The electronics device you need for this is Router. You can use Router for less distance and offers a lot of high speed Net service. In your Smartphone’s Charge is less finished.
: All the Network Provider Company. They compare make Wi-Fi much cheaper plan can not give you any more. Whatever data remains in the mobile plan is in a few GB. If we talk about Wi-Fi, then you can get a 50 GB plan and more.
You do not need to spend limited amount of DATA in it . But Sim like Airtel, Reliance Jio, Vodafone offers Companies which plan he limited lives.
If you use more than the limit in the mobile network, then the money is cut from the main balance. In mobile, you have to think every time which video to watch and which one to watch. Only you will concentrate on data saving. Therefore, Wi-Fi is the best in terms of Net access and data.
A Wi-Fi Network on the Internet which speed is the Comparison If we Mobile Network Speed it will Wi-Fi’s speed is much higher. In a mobile network, if you are reading some mail and if you are reading online book then by then the speed of the mobile is quite right.
When it comes to Video and Audio Downloading the Wi-Fi is nothing faster than ever.
Live streaming if you are doing it from your mobile. Just waiting for loading in mobile. No one can compete with WI-FI in speed. Speed around 1mbps to 100 mbps is up.
: Now Jio is 4G so people do not know how much is the bill. But the price of mobile data was one year ago. Recharge before nearly 100 had to think again. So far, you have used free data of jio.
If it is calculated , then it is common for a bill of 1 lac If you take a Wi-Fi connection at home, then you will get a very cheap plan at a low cost.
Which you do not have full alone Family can be used. Due to being cheap, in Hostel, College, School, Office etc, use this cheap Internet Connection. You can also reduce 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 Wi-Fi
This technology is quite user-friendly. You easily any of the smart phone , Tablet and Laptop to Wi-Fi with Connect can do when he Device Wi-Fi the Range should be.
It is very easy to use it, just you have to turn on Wi-Fi. If there is a password Enter password and connect. Enjoy the Internet.
Mobility means you also walking anywhere Internet to Access can. Such as Bus, Train, Coffee shop, Super Market where it is network.
The same Wi-Fi Device with lots of other Mobile Devices to Connect can. For example, 5 to 6 mobile devices can connect with a Router. It takes you very little time to do this connection.
As you know it is very easy to access Wi-Fi 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 already plenty User Wi-Fi to Connected and you want to a Device the Connect to be. 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 .
The most important and important advantage is that it is quite standardized . Meaning a Wi-Fi Router can run in all countries of the world .
Disadvantages of Wi-Fi
Performance / Speed
You Well Market in Gigabit Speed with Wi-Fi will get but so far they have all Location in Gigabit Speed is not available. But Gigabit Speed is available in Cables .
Connectivity / Reliability
It is a medium dependent network . This meant Wi-Fi Signal Unable to use any move across the wall as Signals of Strength decreases. You know Wi-Fi has a fixed range .
A Fixed Location in Wi-Fi for Access can. The farther you go, the lower the strength of the network will be. Like 10 meter to 20 Meter will have to remain within.
Nowadays , anyone can enter your system via Wi-Fi and steal your data . So this is the biggest loss of this technology .
