Wifi Definition and Advantages of Wifi || How does Wifi work
Friends, please provide me LAN, my data is over nowadays. You'll usually hear this from the mouth of your friends or generally you'll conjointly want additional knowledge and you have got conjointly used the net from different friends. In such a condition, we tend to do take the name of , therefore here comes the issue that have you ever tried to understand what wireless local area network is. Many of us wish to understand what's the vary of wireless local area networks as a result of over and over they get out of the house and wish to use it around their area too.

People, who understand it and need to use it additionally skills to induce wifi? except this, you'll conjointly recognize what its full kind is and the way of its works. If you are doing not acumen a lot of travel the net had to jaunt reach wirelessly via cable, then I will be able to tell you during this post.



Have you ever tried to understand before when there have been no mobile networks individuals and other people wont to confer with one another only through phone to phone and the way people wont to run net at that point? Therefore let me tell you that at that point net affiliation was taken by cable and it absolutely was additionally dialed to attach the net, it wont to take tons of your time.


In the past, it absolutely was impractical for everybody to use the net. Individuals had to go to net cafes, however, nowadays the net has reached everyone's hands, which works in no time. And there's no want for any cable. We have a tendency to use Wi-Fi to use the net on our laptop, computer, thus what's this local area network, we are going to apprehend more. If it didn't happen, then suppose that even nowadays, by connecting this cable to our PC and computer, we are going to additionally apprehend what's its history through this post.


Wi-Fi Definition


We conjointly speak LAN by this name, Wi-Fi could be a local area network wireless technology. This can be a method within which Wi-Fi helps in transferring information from electronic devices and connecting to the web exploitation ism radio bands. This technology comes below the local area network, which implies that its vary is proscribe to the world.

 Wi-Fi helps computers and different devices communicate with the assistance of a wireless network. Through this technology, we have a tendency to are able to connect mobile smartphones, tabs, desktop with a LAN electronic device, and laptops to the net in a veru restricted space. During this manner we have a tendency to don't would like any net broadband nor any net reference to cable property.

 Full form of Wi-Fi

 The Wireless Fidelity Alliance has given it a reputation as a format we frequently apprehend because of the full-form LAN of Wi-Fi.

 Have you ever used this service?
Your answer are affirmative

 Whenever your mobile knowledge gets exhausted, you'll still be talking to a follower, brother, provide the info for a moment. At that point, your friend is hotspot ON on your phone and you'll have an online association by turning on Wi-Fi on your movable. Currently you answer my question. Has Wi-Fi proven to be terribly helpful for you or not?

 Your answer also will be that affirmative it's a awfully helpful technology. As a result of electronic equipment and cable net isn't needed to run net in laptop computer and desktop conjointly.

 Wi-Fi is employed in several devices like laptop, game console, smartphones, etc. To create use of Wi-Fi, we have a tendency to additionally build a hotspot that incorporates a vary of twenty meters (66 feet). Wi-Fi network parts are supported 802.11 standards developed by IEEE. It provides a regular thanks to connecting with wireless networks. Allow us to recognize what are the standards and standards utilized in this.

 Wi-Fi standards in chronological order

  • 802.11a
  • 802.11b
  • 802.11g
  • 802.11n
  • 802.11ac
If a wireless access point is 802.11b or 802.11g, then their range is indoor i.e. 120 feet indoors and 300 feet in outdoor open space. You may not have noticed but our smartphones, printers and laptops have a Wi-Fi chip. Through this, our device is connected to the wireless router and allows us to run the internet. Today, we use the internet everywhere through wireless networks whether sitting or roaming outside. But how it works is also an important question, so let us also know how this Wi-Fi works?

 How does Wi-Fi work?
If you ever go to the airport, coffee shop, railway station, then you are definitely in the Wi-Fi zone at that time. There are many cities where the government has set up a Wi-Fi zone where people can go and use the internet for free, but have we tried to know how this technology works. Any wireless network uses radio waves as do mobiles, televisions and radios. Understand that whenever there is wireless communication it is always two-way radio communication. Let us now see how this happens.

1. The wireless adapter of our laptop converts the data into radio waves and transmits it using an antenna.

2. The memory router gets the signal and decodes it. The router sends information through the physical wired ethernet connection to the internet.

The same process also works in reverse, in which the router receives information from the internet. It then converts it into a radio signal and sends it to the laptop's wireless adapter. Radio waves in its network work in exactly the same way as radio waves in walking-talkie and cell phones. The Wi-Fi chip of our mobile and other devices can transmit and receive radio waves. And these chips can convert radio waves into 1 and 0, then 1 and 0 back into radio waves.

 Friends, you must have already understood what is its working process, let me explain it with a practical example now. When i took a broadband connection, i was given a cable which i used to use as a LAN cable in my laptop. But then i put it in my D-Link router and now a Wi-Fi network has been created inside my room, so now i can access the internet without wire and cable from any part of the room or outside the room. So here you saw that to create a wireless network from the router, an ethernet cable was required which provides internet connectivity, whereas the router provides us with a Wi-Fi zone for us as a wireless network.

 If we talk it in simple language, then suppose when you turn on the hotspot of your mobile then there is an adapter inside your mobile, it turns the data into radio waves and makes it a Wi-Fi zone. In a way, it becomes a WLAN (Wireless Local Area Network), within which any mobile, computer, laptop can connect to it. Its radio signal is not strong, so its signal goes only for short distance (15-20 meters).

 Now when you connect your laptop or other device to this Wi-Fi network, it establishes internet connection with that device. In this way, the device that we have made hotspot is also connected to the internet and act like a router, which converts and transmits the data / information of all the devices connected to radio waves. And then also converts radio waves into data / information. That is, it works as both router and transmitter. Now you must have got an idea how Wi-Fi works.
Nowadays almost every device like mobile, tablet, Ipad, Laptop has inbuilt Wi-Fi adapter, which makes internet access easy. But desktop computer does not have inbuilt adapter but we can use it by connecting adapter via USB port separately.

History of Wi-Fi

Although Wi-Fi was started for the general public in 1985, its foundation was laid 14 years ago. It started when in 1971 the university of Hawaii presented to the public for the first time a demo of the wireless packet data network, ALOHAnet, which was based on UHF (Ultra High Frequency) radio waves. Then in 1985, America's Federal Communications commission (FCC) announced that anyone can use the wireless spectrum to communicate without a government license. The released frequency in this was 900MHz,  2.4 GHz, and 5.8 GHz. In 1985, IBM introduced the Token ring LAN with a speed of 4 Mbps.

CR and AT&T Corporation together proposed to start WaveLAN which would replace the Ethernet and Token Ring systems. It would work at 900MHz or 2.4 GHz and had a speed of 1 to 2 Mbps. After 1989, the WaveLAN design was submitted to the institute of Electrical and Electronics Engineers 802 standard committee.

Father of Wi-Fi

In 1990, the IEEE 802.11 wireless LAN working group was formed, headed by Vic Hayes and also called Father of Wi-Fi. In a conference in San Francisco, Henrik Sjodin proposed a proposal to build a public access local area network that could be used by the man. Although its name was not thought at that time, but today we know it as "Hotspot".

AT&T at Carnegie Mellon University completed the largescale installation of its WaveLAN project. This was the first step to test this system which was completed in 1993. Dr. of Carnegie Mellon University Alex Hills started wireless research and aimed to cover 7 buildings on campus. The name of this project was Wireless Andrew and the National Science Foundation invested money on it.

Then in 1997, the first version of the 802.11 protocol was released and it had a capacity of 2 Mbps speed. A year later, a new revolution started in the world, which was already laid but started from here. Mark Google And Greg Jackson's company mobile star, which was a wireless internet service provider company. This was the first company to name the term "Hotspot" and also started its service. Mobile star became the first company in the world to provide internet access through hotspot at airports, hotels and coffee shops and also signed contracts with American airlines, Hilton hotels, and Starbucks.

Wi-Fi Alliance was formed in 1999 which was a nonprofit trade association. It took the responsibility of the Wi-Fi trademark to give the user experience and started verifying all the products as well. The same year Apple introduced Wi-Fi slots in its iBooks called "Airport". After this, the 802.11b standard was approved, which had a frequency of 2.4 GHz and speed 11 Mbps. A month later, the 802.11 A standard was also approved. Its speed was very high. It had a speed of 54 Mbps in a frequency of 5GHz. After this,
  • 1999-802.11b
  • 2000-802.11a
  • 2003-802.11g
  • 2004-802.11i
  • 2005-802.11e
  • 2009-802.11n
  • 2009-802.16 WiMax Protocol
After this, the number of Wi-Fi hotspot in the world had reached 1million in 2010, then-President Barack Obama signed a memorandum to free 500MHz frequency for the wireless industry.

2014-802.1ac standard was approved, which had an amazing speed of 1733 Mbps and a frequency of 5GHz was used for this. In 2015, the number of Wi-Fi hotspots worldwide reached 70 million. So friends, you now know how old the history of a wireless network is and it has reached us after a long journey.

Best Features of Wi-Fi

Everyone wants that its speed is fast and safe, besides it is necessary to have good features. So let's know what are those features that must be in your Wi-Fi.

High Capacity Load Balancing

Initially the wireless network was built keeping in mind only the coverage. But come such a time has come when everyone has many devices and they use many devices simultaneously for connectivity of internet. That is why it is very important to have the ability to balance load capacity in these days. So that according to our wish, we can use many devices with good speed.

 Indoor and Outdoor Coverage Option

 By the way, you would think that it should be used only in the room or inside the house. But when you look outside now, its zone remains in a railway station, airport, bus station also. If you ever go to a router, then also keep in mind that in this we have the capability of outdoor coverage.

 Scalability

 The popularity of new wireless devices always increase. Your wireless system should have this capacity, so that it can work to increase the capacity and coverage according to your needs, both small and big scale according to your requirement.

 Speed

 Have you ever used railway station Wi-Fi? If used, then you must know what the speed is like. When you do the internet on mobile, then its speed works compared to Wi-Fi. When we use a wireless network to download a movie, it is downloaded much faster than mobile. If you talk about live streaming, then it takes time to load a video on mobile internet but in Wi-Fi the video plays without buffering with good quality.

 Mobile Device Management

Now, Once you think how many mobiles you will be accessing in your wireless network. Now when so many mobile devices will connect to a network, then thousands of applications will also be run in it. Now how will you manage all these in it when one device comes and then another device will come and connect. With the help of Mobile Device management, you can control all these applications at your own will. You can remotely remove a device that has been lost or stolen from this network.

 Efficiency

 Have you ever noticed that when you use mobile in normal life and when traveling on a train, you use your mobile battery quickly. Yes, actually when we are traveling, the network changes frequently. Because of this, the battery gets depleted very quickly. Whereas if we talk about this service, they use radio waves. Because of which the battery of the mobile does not drain quickly.

 Affordable

 Friends, when we use internet of a network in mobile, then a limit is given in it that you can use this much data. But if you use it, then it also has unlimited plan and speed is also constant. There will be no limit to use data for you. You can download the maximum amount as you would like. If you calculate the data too, you will find it very cheap compared to the mobile plan.

 Advantage of Wi-Fi

  • It is very easy to add and remove clients to its network made up of Access Points.
  • It is easy to install and gets done very quickly. It is also not necessary to have technical knowledge for this.
  • To access its network, other devices only need a password. That is why there is no need to do much for connectivity in this.
  • Wi-Fi enable USB Dongle is available in the market for a very good price. And you can buy USB dongle of TP-Link, D-Link and Tenda at very cheap price.
  • The most recent standards versions are 11n and 11ac which deliver data at much faster speeds, with speeds up to 300Mbps and above.
  • It is quite easy to integrate its function in mobile devices. Millions of people use smartphones today, in which Wi-Fi facility is provided inbuilt.

Disadvantages of Wi-Fi
  • When the number of devices in the same network increases, the data transfer rate works.
  • Due to this system being wireless, it is very difficult to give full security in it. This requires proper security authentication protocols and configuration.
  • Such devices work with full functionality in the range of Access Point and good signal strength. The best range to access Wi-Fi is from 30 to 100. Its strength decrease when going out of it.
  • If ever this service does not work then it needs to troubleshoot. For this, it is necessary to have basic knowledge of the device.

How to get Wi-Fi

If you want to use this service, then you must first find out which networks are available in your area which are offering this service. Tikona, Spectranet, ACT Broadband, Airtel Broadband Service if any of these services are available in your area, contact them and inquire about their plans. Apart from this, BSNL is available in every part of india and very soon Jio fiber will also reach your home. If Tikona is available in your area, take service of it; take it because they give very cheap and good plans.

Choose any of these services and choose a plan. After this, you will need a router to create a Wi-Fi network in your home. In this, you connect the Ethernet cable of the broadband network and access the router and set the user ID password. This way you will get your Wi-Fi network ready.

What is the Wi-Fi range?

Generally, the network traditionally used for 2.4 GHz band is in the range of 150 feet i.e. 46 meters indoor. If you talk about outdoor, its range is 300 feet i.e. 92 meters. In comparison, the old router which was of 802.11a had a band of 5 GHz and its range was less than 3 times.

In Short

Just think once, if there is no Wi-Fi in today's time, how would we use the internet in computers, laptops and mobiles?After its arrival, you take the laptop in your hand and go anywhere and use the internet. Even when the data in the mobile is exhausted, the friend's internet is also used with its help. Today you know what is Wi-Fi and how to get Wi-Fi installed. Apart from this, you have also known what its full form is, and how it works.

We do use it sometimes, whether from our friend's mobile phone or the railway station network. Its history is very old and we also talked about it in this post, what is its history and how did it reach us.

We already know its many advantages, but we have also learned some of its disadvantages here. So friends, how did you like this post, let us know by commenting. If you like this post, then definitely share it with you. So that they too can get information about this.
