LI-FI vs WI-FI

Wht is LI-FI ?

How would you feel if someone told you that you would turn on the bulb and your internet would run ?
Obviously you will make fun of him.

Yes, you understand that such technologies are going to come in future, which we will know by the name of LI-FI

We all know about wifi networks which we use on daily basis for the purpose of data transfer from one device to another without any wire.
But if we talk about future the wifi is nearing it's end.

As we all know that radio waves are used in wifi which creates radiation's and are very harmful to health.
One more demerit of wifi is that anyone with some hacking tools can hack your wifi and hack your personal data.
The speed which we get through wifi is also limited.

But a new era is coming named as LI-FI  in which light is used to transfer the data from one device to another.
We all know that hacking light is not possible so it is considered as a positive point in the favour of LI-FI
✓It can also be use underwater
✓speed of Li-fi will be around 240 GBPS


INVENTOR:

LI-FI was invented by HAROLD HAAS from the university of Edinburgh, Scotland back in 2011,when he demonstrated for the first time that by flickering the light from a single LED he would transmit far more data then a cellular tower.
