What is WiFi?

What is WiFi? technicalkanu.tech/2019/03/what-is-wifi.html

Do you know what is WiFi and what is the history of this technology? In the world, there have been many years of Internet coming in the world but do you know how difficult it was to get an Internet Connection. Internet was born from the network. The only way to send any information digitally in the past was to cables the only way.

Internet Connection was only taken from Cables. But you must know that we like to work with people without rest and without any hassle. I used to think about how the Internet can work without even Cables.

Due to day-to-day changes, Computer Scientist finally created an AC Wire Less Technology called WiFi. Nowadays everyone from this wireless technology is quite a bit aware of what is quite a lot. The new generation of young people is connected to the Internet through wireless technology. So let's see in detail what is the Wi-Fi

What is Wi-Fi? The full name of WiFi is Wireless Fidelity. This is a popular Wireless Networking Technology. An AC technology, through which we have been using Internet and Network Connection today. Now in your easy language, this is the technology through which we are now enjoying the Internet in our Smartphone, Computer, Laptop way wirelessly.

Through this, we can join you and you can join the internet within the limited space.

Today, everybody has access to the Internet via WiFi, and simultaneously, Data Transmit also happens as you do with Shareit and Xander. WiFi has emerged from the wireless and Hi-Fi word.

The following are the examples of the WiFi Standard, which will be understood when you discuss further history.

802.11a 802.11b 802.11g 802.11n 802.11ac

WiFi is a standard. The standard we follow, connect the computers to the wireless network. Currently,y there are Smartphones, Laptop, Printer, and Computer. All of them have a WiFi Chip. Through which we and you connect to the Wireless Router and use the Internet.

Once Wifi is enabled, once you connect to the wireless router, you can access the internet. But the Router also has to use DSL and Cable Modem to stay connected to the Internet. Otherwise, there is no Internet access. WiFi is similar to Hi-Fi, whose full form is High Fidelity. WiFi's full form is not Wireless Fidelity. It's just a name. Selected

by WiFi Alliance. It is also known as WLAN.

It uses Technology Radio Waves. You roam the Internet while roaming. Now let's know how Wifi Technology works.

How Wifi Technology Works?

Today everyone is using WiFi. Whether it is in the office or at home or in the hostel, but nobody knows how this technology works. To use this technology first, we need an Electronics Device. Which is called Wireless Transmitter / Hub / Router. This creates a Device WiFi Network.

It receives information through Wireless Device (Router), Broadband connection. Now there are some components inside it. Which converts this information into Radio Waves. This device emits out of these Converted Waves. Through this process, the area of a small Wireless Signals is formed. Which we call the WiFi zone.

This small area takes the form of a WLAN (Wireless Local Area Network). All the devices in this small area such as Smartphone, Laptop, Printer, if all of these devices have a built-in wireless adapter. With the help of which can easily get WiFi Signal.

One thing to remember if a mobile phone is connected to WiFi. Understanding this is the wireless adapter in that device. Due to not having Radio Signals Strong, the distance of this network remains limited. Just like in a house and in a nearby house, by the side of the road. It means its range ranges from 10 to 20 meters.

Radio Waves can easily move to the other side of the wall. For this reason, nearby rooms also have Internet access. However, a wireless router for a home is enough. As much as you go to the Router, the internet will also be so strong that the network will be as strong.

When you send back some information (Text, Image, Audio, Video) to Wireless Transmitter / Router, the same process will run in the opposite. As if you are connected to WiFi, I mean your Mobile. EX- You have sent a text message to your friend. It converts into Radio Waves before moving out of Message Mobile and after reaching the signal to Transmitter / Router. Converts transmitter/router text into signal and transmit it to broadband and in the same way remains the address of the receiver. You must have known, some way WiFi works like this.

Important information - There are some Devices like Mobile, Laptop, and Tablet in which Wireless Adapter is already in. That is why most of the smartphones get Internet access from WiFi. There are some things like Desktop, they do not have a wireless adapter. That is why they have to buy a Wireless card or Adapter. Which is then used in the USB port of the desktop. We can also access the Internet in the Desktop.

Features of WIFI We have a lot of other ways that we use the internet but the question is whether there are such features for which this technology is special, then let's go friends know what is the specialty.

1. Efficiency We can not speak Efficient when he is not perfect in any technology. Everyone today 3/8

uses the cellular network for the Internet. But you do not know the area of the cellular network is high. But when you are in a moving vehicle you use the internet but you often get connected to different networks. That's why your mobile's energy is more complete. Now the energy can say battery or charge.

But if we talk about WiFi, then it uses Radio Waves. The Electronics Device you need for this is the Router. You can use the Router for a low distance and serve a lot of High-Speed Net. In this, your smartphone's Charge is also less finished.

2. Accessibility As much as the Network Provider Company. Compare them with the cheapest plan and no one can give you the cheapest WiFi. Any data stored in the mobile plan is in some GB. If we talk about WiFi then you can get a 50 GB plan and even more.

Whatever you spend in DATA, there is no need to be limited to you. But plans like companies like Airtel, Reliance Jio, Vodafone, Sim are limited.

If you use more than the limit in the Mobile Network, then the money is deducted from the main balance. You have to think every time in mobile that you have to watch the video and not see the angle. Just keep you focused on data saving. In terms of network access and data, Wifi is most accurate.

3. Speed Comparison of the speed of the Internet in a WiFi network. If we do Mobile Mobile with Speed, then this speed of WiFi is much higher. If you are reading some mail in the Mobile Network and reading the Online Book Book, then the speed of mobile is largely fine. When talking, video and audio downloading have nothing faster than WiFi.

Live Streaming If you are from your mobile There is just waiting for mobile to be loaded on the mobile. Can not make any collision with WiFi in speed The speed is approximately 1mbps to 100 Mbps.

4. Cost Now Jio 4G is why people do not know how much the bill is. But that was the price of Mobile data a year ago. Before recharging, had to think about 100 times. So far you have used jio free data as much as you have. If it is calculated, it is common for a bill of 1 lakh to come. If you take any WiFi connection at home then you will get a very cheap plan at low cost.

You can not use your whole family alone. Due to the cheapness of Hostel, College, School, Office Vigera, this cheap Internet Connection is used. You can also minimize your Mobiles' bills through online video calling and voice calling. So this 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 is in the Range of Device Wifi.

2. Simplicity It is very easy to use it, you just have to turn on Wifi. If there is a password. Enter the 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. Like 5 to 6 Mobile Devices can connect with a Router. It takes you a lot less time to do this Connection.

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

6. Cost Control

5/8

If already many users are connected to WiFi and you want to connect a device too.

For this, you do not need to spend any extra and no cables. Now talk about Broadband Connection, you need Cables and Reconfiguration in it.

7. Standardization The most special and necessary benefit is quite standardize. Meaning a WiFi Router can run in all the countries of the world.

Disadvantages of WiFi 1. Performance / Speed You will find WiFi with Gigabit Speed in the Market, but Gigabit Speed is not available in every location. But Gigabit Speed is available in Cables.

2. Connectivity / Reliability This is the Medium dependent network. This means that the WiFi signal decreases the strength of the signals as soon as you cross the wall. You know that WiFi's Fixed Range stays

3. Distance You can access WiFi in a fixed location. The smaller the strength of the network, the less power will go away. Just like to stay within 10 meters to 20 meters.

4. Security Today, anyone can steal your data from any system through WiFi. So this is the biggest disadvantage of this technology.

History of Wi-Fi WiFi was born in 1985. United State FCC, when it allocated, can use Wireless Frequency 900MHZ, 2.4 GHz and 5.8 GHz, without any license. Then its history had begun.

Perhaps you would not know these bands were used in home appliances such as Microwave Therefore it was believed that there is no use of them. There is no use in communication, especially in communication. That's why the FCC made its use mandatory to make this band worthwhile. Named after Spread Spectrum Technology

The license of Spread spectrum technology was taken in 1941. The licenses were to be taken by George Antheil and Actor Hedy Lamarr. This was the technology through which the signals were sent with multiple frequencies. There may be nothing to do with this change, but after that technology, there was considerable improvement in the wireless signals. It failed to solve the Technology Interference Problems. Because at that time the mobile already had Radio Install. Because of which the quality of the signals had a significant impact.

At the same time, there was a technology emerging, named WLAN (Wireless Local Area Network), which had many technical problems. There was no standard of WLAN. There was a lot of confrontation in connecting different Company's Devices.

In 1988, the then NCR Corporation needed a wireless cash registrar. That is why he had done the mission of making Institute of Electrical and Electronic Engineers (IEEE) 7/8

a standard with the cooperation of Victor Hayes and Bruce Tuch. Standard was ready in 1997 and the name of which was very attractive was the name "802.11". It was published in 1997 itself.

At that time the speed of DATA transfer in 802.11 standards was about 2 megabits per second. In 1999 it was published 802.11a. The speed of which was about 54 megabits per second. It was quite expensive so its next version was published, which was named 802.11b. It was started with WiFi Technology, this version was cheap and the Range of this network was also very much.

802.11b Because of the folk darling within a short span of time, Wireless Technology was in a way bound. It quickly established its status in the Hardware Market. Due to range and compatibility, there was considerable reasoning.

For this reason, 6 companies constituted a Wireless Ethernet Compatibility Alliance or WECA. Through which it was tested whether WiFi is Compatibility or not

In 2002, he was taken from the word Wi-Fi, Wireless and, a word HiFi. Whose name came to be known by the Wi-Fi Alliance a few years later Now you can understand what is the history of WiFi

Conclusion I always hope that you get accurate and complete and complete information. What you know today is WiFi and what is the history of this technology. You are more likely to benefit from the advantages and disadvantages of wifi. Increased LiFi from wifi in the future has come.
