About Wifi full form-Hello friends, today in this article we will know. What is Wifi, what is Wifi full form, how to connect Wifi, what is the range of Wifi. If you do not know much about Wifi, then this article is for you only.
What is Wifi, when was Wifi invented (What is Wi-fi, Wi-fi invention, full form)
Friends, you all know that the Internet was invented many years ago. But at that time the Internet was not used much. Because a lot of cables were needed to use the Internet. Which was a difficult task. People used to go to cafes to run internet.
To deal with all these difficulties computer scientist Invented Wifi. Wifi was invented by John O Sullivan and John Dean in 1991. Wifi technology in 1998 Wi-fi Alliances The name was presented by the company. Wifi is a popular wireless Technology is the name of. This high speed internet and network connection Uses radio signals to deliver.
What is the full form of Wifi (What is full form Of wifi)
Friends, the full form of Wifi is “Wireless Fidelity”. Wi-Fi is also known as WLAN. Whose full form is “Wireless Local Area Network”, this is a technology through which today we are using internet and network connection.
With the help of Wi-Fi, you can easily get mobile, Laptop,Computer And printers can be connected together.
Types of Wi-fi
There are mainly three types of wireless networks – WAN, LAN and PAN:
1)WLANS: वायरलेस लोकल एरिया नेटवर्क 2)WPANS: वायरलेस पर्सनल एरिया नेटवर्क 3)WMANS: वायरलेस महानगरीय क्षेत्र नेटवर्क 4)WWANS: वायरलेस वाइड एरिया नेटवर्क
What is the range of Wi-Fi
The range of Wifi is not very long, the range of a 2.5 -5 gigahertz Wifi is about 150 to 300 feet. This technology comes under Local Area Network. Through this we can connect to the internet up to a limited place.
Today Wifi has become so much advanced that through this we transfer data apart from internet.
How does Wifi work(How does Wi-fi work)
in today’s time each computer, laptop And there is wifi in the mobile. This Wifi is a small one. This chip is fitted in the electronics devices, this chip transfers the wireless signal. After that we connect it through wireless router and use the internet.
Friend Routers also have to use cables etc. to connect to the Internet. Which is connected to the internet service provider (ISP). friends off Wi-fi radio waves It can also go across the wall. With which WiFi can be used in other rooms of the same building as well.
Wifi speed depends on the distance from the router. The longer you stay, the lower the speed will be.
What are the benefits of Wifi
1) This technology is quite user-friendly. Meaning you can easily connect any Smartphone, Laptop to Wi-Fi.
2) It is very easy to use. Just have to turn on Wifi, if there is a password, then it has to be connected by entering it.
3) Earlier it was difficult to get wifi everywhere but in today’s time wifi is available everywhere. You can use any of your friend’s wi-fi while on the go.
4) You can connect many devices to one wifi. And at the same time all the devices can get access to the internet.
5) The speed of wi-fi is much faster than mobile network. You can take advantage of the speed from 1mb/s to 300mb/s.
WiFi was born in 1985, when the US FCC announced that wireless frequencies 900MHZ, 2.4 Ghz and 5.8 Ghz could be used by anyone without a license. Then the Wi-Fi story begins.
You may not know that these frequency bands are used in microwave ovens and other home appliances. That’s why people think they are worthless. Particularly useless in communication. Therefore, to make this band available, the FCC mandated its use. This is called spear spectrum technology. The spread spectrum technology license was obtained in 1941. George Anthill and actress Heidi Lamar first got permits.
It is a technique of transmitting signals with multiple frequencies. This change shouldn’t cause any problems, but there were many improvements to wireless signals following this technology at the time, and they didn’t solve the interference problem. Because at that time the radio was already installed in the mobile phone. Because it has a great impact on signal quality, a technology called WLAN (Wireless Local Area Network) has also emerged, but with many technical flaws. There seems to be no standard for wireless LAN. There are many difficulties in connecting the devices of different companies. In 1988, the NCR company at that time required a wireless cash register. That is why he tried to make the Institute of Electrical and Electronics Engineers (IEEE) a standard with the help of Victor Hess and Bruce Touche.
The standard was created in 1997, and has the catchy name “802.11”. It was released only in 1997. At that time, the data transmission rate in the 802.11 standard was about 2 megabits per second. 802.11a was released in 1999. Its speed is about 54 megabits per second. It was too expensive, so the next version was released, called 802.11b, which started with WiFi technology, this version was much cheaper, and the coverage of this network was also very high, because somehow it could reach the technical fence. has gone. Soon, it established its position in the hardware market. It is very famous for its range and compatibility. For this reason, 6 companies have formed the Wireless Ethernet Compatibility Alliance, namely WECA. Use it to check whether WiFi can be copied or not. In 2002, it was renamed Wi-Fi, Wireless, and a term derived from HiFi. A few years later, it was renamed the Wi-Fi Alliance. By now you must have understood the history of WiFi.
