Hey guys.
If you want to know that what is lifi and know about and how it would be updated , so let us start.
Lifi means LIGHT FEDELITY.
You all have heared about wifi and all of u have used the wifi which basically runs on the principle of radio waves but the the lifi tecnology is a fully modern tech which transmits the data using the visible lights.
As u can see in the pic that how the data is transferred using LED lights .
In the technical words LIFI can be termed as a wireless communication tech which utilizes light to transmit data and position between devices .
It was introduced by Harald Hass in 2011.
Lifi works by switching the current supplied to the led bulb at a very high speed which can not be noticed bu the human eyes.
How Lifi Works
As u can see in the picture that the internet connection you are getting from the backside goes through the lamp driver and lamp driver fluctuates its power level and with the support of this Led lamp has a variation in its output intensity and finally u get the connection through the reciever dongle by the photo detector.
This was the basic concept of the LIFI
BASICS OF LIFI
Lifi connection automatically switches its light source as u move from one source to the another light source , it not disconnects it remains connected.
Benefits of lifi
Lifi has a high speed of 100 gb/ps as tested and it has a bandwidth more than 10000 times than rasdio waves as tested.
It means that in parallel many connections could be operated without any interferance.
No radiation
Applications
It could provide smart lightening as in the street lights it could produce data hotspot at low cost
All the smartphones . laptops could be connected since the range would be lower but the data rates would be much higher and maximum security.
Lifi could also be used in the hazardous environments such as mines , petrochemicals plants
Lifi can also be used in the airplanes and underwater.
Smart driving cars could be connected.
THANKS
