What is Li-Fi technology and how does it work (Difference between WiFi and Lifi)

Technology and Internet are developing very fast, in the meantime you have Internet But you must have heard about Li-Fi too. This is a latest technology in which you can access internet through light. Still many people do not have the right information about Li-Fi, so they keep searching on the Internet. Li-Fi Kya Hai In Hindi.

If you also do not have information about Li-Fi, then read this article till the end, in this we have given you complete information about Li-Fi.

In this article you will get to know that Li-Fi what Is, Li-Fi Work How does Is, Li-Fi of Use what Is, Li-Fi Of Advantages And Harm what Is And Li-Fi And Wi-Fi In what gap Huh, So stay tuned till the end of this article, let’s start this article without any delay.

What is Li-Fi Technology

Li-Fi, whose full name is Light Fidelity, is a type of technology through which you can connect like Wi-Fi. wireless In this way you can connect your devices such as Smartphone, Tablet, Laptop etc. to the Internet. The data transmission in Li-Fi is done through the light, and the LED bulb acts as the router.

What is Li-Fi technology and how does it work (Difference between WiFi and Lifi)

This technology is very similar to Wi-Fi, but is capable of transmitting data at a much higher speed than Wi-Fi. Li-Fi is used in places where radio waves are obstructed, such as in airplanes.

Full form of Li-Fi (Li-Fi Full Form in Hindi)

The full form of Li-Fi is Light Fidelity, it is also called Light Fidelity in Hindi.

History of Li-Fi

In 2011, Professor Harald Haas of Edinburgh University talked about Li-Fi technology, he is considered the father of Li-Fi technology. In the year 2013, his company commercially released the world’s first Li-Fi technology.

In 2011, when Harald Haas introduced people to Li-Fi technology, it was only after that he started a company called PureLiFi. Earlier the name of this company was PureVLC.

Introduced in 2015, Li-Flame was the first Li-Fi product to support wireless mobile communication.

In 2017, LiFi-XC System was launched, it is a plug and play system which USB Works with the device. In future it can be integrated into smartphones, laptops, tablets etc.

Development is still going on in Li-Fi technology, it is believed that very soon this technology will become very popular and every user will be able to use it.

How Does Li-Fi Work?

Since Li-Fi and Wi-Fi technology are similar, the functionality of Li-Fi is also similar to Wi-Fi, as the transmission of data in both takes place in the form of electro magnetic. In Wi-Fi data is transmitted through radio waves, while in Li-Fi data is transmitted through light.

Just as the router is used in Wi-Fi, in the same way LED Light used in homes in Li-Fi, router works of.

There are mainly three components used in Li-Fi – Lamp Driver, LED Lamp and Photo Detector. Apart from these, you also need an internet connection.

The main source of the internet is connected through the lamp driver, the information of the internet received by the lamp driver is sent to the LED lamp, after which the photo detector receives the light coming out of the LED lamp and then transmits the light signal in binary data. and finally sends the data to the smartphone, laptop or computer for further processing.

The entire process of data processing in Li-Fi is done with the LED lamp on, if the LED light is off then you cannot access the Internet.

Uses of Li-Fi

Following are some of the major uses of Li-Fi –

  • It is used in airlines because it radar As such does not interfere with aircraft equipment relying on radio waves.
  • Li-Fi is used in underwater exploration because light can travel through water.
  • Li-Fi is used in hospital operation theaters because light has little effect on medical equipment.
  • Li-Fi is also used for data transmission and internet browsing in offices and homes.

Advantages of Li- Fi

Following are the advantages of Li-Fi technology –

  • Interference is less in Li-Fi.
  • Data can be transmitted securely through Li-Fi technology, so this technology is very beneficial to prevent activity like hacking.
  • Wi-Fi The speed of Li-Fi is much higher than that.
  • Since light can travel through water, this technology can be used under the oceans.
  • Li-Fi is a cheap and efficient technology as compared to Wi-Fi technology.
  • Every light source can give you internet access via Li-Fi

Disadvantage of Li- Fi

Following are the disadvantages of Li-Fi –

  • To access the Internet through Li-Fi, it is necessary to have a light source, without a light source you cannot use Li-Fi technology.
  • The range of Li-Fi is limited, it can only cover an area up to 10 meters.
  • A separate network is required for Li-Fi connection.
  • Li-Fi can be expensive to install at the present time, but it is more likely that in the future there will be more ground improvement in this technology, which can reduce its cost.

Difference Between LiFi and WiFi

We have told you the major difference between Li-Fi and Wi-Fi through the table below.

Li-Fi (Light Fidelity) Wi-Fi (Wireless Fidelity)
In Li-Fi technology, data is transmitted through light. In Wi-Fi technology, data is transmitted through Radio Wave.
LED Bulb is used to transmit data in Li-Fi. Transmits data via Wi-Fi router.
Li-Fi is used for internet browsing on airlines, underwater exploration, operation theatres, in the office and at home. Wi-Fi Hotspot Internet access is done through.
The speed of transmitting data is around 1 Gbps. Capable of transmitting data in a range of 150Mbps up to a maximum of 2Gbps.
Light is prevented from passing through the walls, so the transmission of data in it is safe. The wall cannot stop radio waves, so other technology has to be resorted to to secure the data.
Li-Fi can only cover distance up to 10 meters. Wi-Fi can cover a distance of up to 32 meters. (Varies depending on transmit power and antenna type)
LED bulb, LED driver and photo detector components are used in Li-Fi. Router in Wi-Fi, modem And access point are used.
Its frequency is 10 thousand times higher than that of radio waves. The frequency of radio waves is up to 2.4Ghz, 4.9Ghz and 5Ghz.
