Everything about Li-Fi Technology (2003 to 2020)


Li-Fi technology is similar to Wi-Fi Technology but different is that Wi-Fi transfer data in the form of radio waves and Li-Fi transform data in the form of light.

It is creating a field of LEDs for Li-Fi and all phones and devices connected to this device when in front of the LED’s Li-Fi.

It was made in 2003 but the final version comes in 2010 for public use. and their growth is counted from 2013.

The deification of Li-Fi (light fidelity) Technology:

Li-Fi’s full name is Light Fidelity (Li-Fi). Light Fidelity (Li-Fi) is a wireless optical networking technology that is used to play high defecation internet and very fast.

Light Fidelity (Li-Fi) is similar to the Wireless Fidelity (Wi-Fi) Technology but the only difference is that,

If you are inside the field mines you inside the visible light of Light Fidelity (Li-Fi). Then it is work but Wi-Fi anywhere work.

In other language:

It works in visible light communication (VLC) and it is the full deification of Light Fidelity (Li-Fi) Technology.

In the above image, we all see one man going from one field to another field but there is no unfairness of the internet.

It is all possible because we use many LED li-fi lights so this type of uses we can control all their limitations and disadvantages.

If we are out of town or out of home then we use tower light witch is can put the one big LED bulb of Li-Fi in the middle of the city in the tower. We are going home, and then we are using our personal LED bulb in our Room or Home.

It’s all about Li-Fi (Light Fidelity) Technology.

Technology Explanation of Li-Fi (Light Fidelity) Technology:

Light Fidelity (Li-Fi) is based on the working of wireless optical wireless communication (OWC) technology,

It uses Light Emitting Diodes (LED) to provide communication, network, internet, and high definition internet but it has this type of LED.

It is similar to Wireless Fidelity (Wi-Fi) but Technology and after some time Light Fidelity (Li-Fi) technology is captured in all markets and dominates the other market.

If all use Light Fidelity technology because Light Fidelity (Li-Fi) technology is given to use very fast data transfer from one side to the other.

It is the last year of 2018 and is a very large quantity of product sales of Light Fidelity (Li-Fi) technology.

Firstly, Their annual growth rate increased by 82% of the market from 2011 to 2018 and It is the next product to replace Wireless Fidelity (Wi-Fi) Technology but they have much flow.

With this technology transforming data in the form of light bimes and what is data?

Secondly, Data is a combination of many bites and bites in a combination of bits like 1 0 0 1 0 0 1 1 1, 1 0 1 0 1 0 1 0, 0 0 0 0 0 0 0 1, 1 1 1 1 1 1 1 1, 0 0 0 0 0 0 0 0, 1 byte have an 8 bits.

Thirdly, All bits or bytes or all data is transfer in the speed of lights because of this is a very fast other data transfer technology. and It is giving us up to 224 Gigabyte/sec.

Fourthly, That works by switching the Visible Light Communications (VLC) current pass through Light Emitting Diodes (LED) off and on at very high speeds.

It is not noticed by the human eye thus Light Emitting Diodes (LED) is transforming data by carrying data.

The distance transfer data is much shorter and much less able to hack the data into the light.

Finally, It is much more secure and much fatter. Next-generation of this technology because of Wi-Fi is close to full capacity, and we need more speed of internet then this technology.

Wi-Fi uses radio webs to transfer data but Light Fidelity (Li-Fi) uses light to transfer data.

History of Li-Fi (Light Fidelity) Technology:

Professor Harald Haas coined the term “Li-Fi” in 2011, In addition, he says it introduced the idea of wireless data from every (Light Emitting Diode) LED light.

Their main purpose in making this transmit the data very fast. and but The basic term of this technology is Visible Light Communication (VLC).

It was introduced in the 1880s, this time to now use Visible Light Communications (VLC) but the 2010 introduction of Digital Communications.

In 2010,

In the first place, It is funded from January 2010 to January 2012. And also Many companies are offering uni-directional VLC (visible light communication).

That is not the same as Light Fidelity (Li-Fi) and This Light Fidelity (Li-Fi) named given by IEEE (The Institute of Electrical and Electronics Engineers).

In 2012,

Light Fidelity (Li-Fi) uses VLC (Visible light communication) technology. After that, he is very popular. That everyone knows this fetcher of Light Fidelity (Li-Fi).

In 2014,

Russian company announced the development of a Light Fidelity (Li-Fi) wireless called Beam Caster.

At this time the current module data transfer rate is 1.25 Gigabyte/second, but we can boost it to 5 GB/s.

He is also saying that in the future Light Fidelity (Li-Fi) will be busted up to 10 GB/s.

How is it similar to Wi-Fi Technology?

It’s all Fetcher’s work, like wireless technology and Wi-Fi — it’s all data transfer wireless, and there are many similarities.

  1. Network topologies for Li-Fi (light fidelity) technology and Wi-Fi (wireless fidelity) technology are point to point.
  2. There are both works on the wireless.

Difference between Light Fidelity (Li-Fi) Technology and Wireless Fidelity (Wi-Fi) Technology:

Why I use Li-Fi (Light Fidelity) Technology:

  1. This is a very fast and Reliable Technology.
  2. There is very little disadvantage of This technique.
  3. There is work in the hole room no other room.
  4. It is very necessary when you want to transfer big data wirelessly.
  5. It is a very low cost from other wireless technology like Wi-Fi (wireless fidelity).
  6. You should go official site

There are some Advantages and Disadvantages of Li-Fi Technology.

Technology never has an Advantage or disadvantage, but they have limitations. I am showing the bellow result:

Cr.Advantage of LI-Fi.The disadvantage of Li-Fi.
1:It’s their transfer of data speed is very fast.It is not able to pass from Wall.
2Their maximum speed reached 224 Gigabytes per second.They have range limitations because they could not pass through such as walls. Although very much signal drop if your moving.
3This is used in Airplanes Hospitals etc. without any interactions.It’s their light beams not have long-range.
4It is cheap to implement and Uses.You use whatever you do not increase the dissidence of Li-Fi Range.

Application of Li-Fi (Light Fidelity):

There are these types of Application we use in Daily Life:

  1. Traffics Management.
  2. For Very High-Speed use the internet.
  3. Medical Lines.
  4. Public Areas.
  5. Rede salty.
  6. Transportation.
  7. Individual Area.
  8. For use in One Room.
  9. Under Water.
  10. Education


In the present time, we all people are not familiar with this new item Li-Fi Light Fidelity but in the future,

All people use Li-Fi Technology because this is very fast. It is their conciliation that all are using this technology.

If I say or My Opinion is that in this, we do not use for this time situation Wi-Fi is very fast and this we have not reached their maximum speed in future increases the speed of Wi-Fi Technology.
