LiFi is transmission of data through illumination by taking
the fiber out of fiber optics by sending data through a LED light bulb that
varies in intensity faster than the human eye can follow.

| A LiFi Environment |
Is It a Proven Technology?
Yes, this is already proven.
Harald Haas demonstrated his invention using an ordinary
table lamp that successfully transmitted data at speeds exceeding 10Mbps using
light waves from LED light bulbs to a computer located below the lamp.
To prove that the light bulb was the source of the data
stream, he periodically blocked the beam of light, causing the connection to
drop.
LiFi Technology At a Glance!
The LED bulb will hold a micro-chip that will do the job of
processing the data.
The light intensity can be manipulated to send data by tiny
changes in amplitude.
This technology uses visible spectrum of light ,a part of
the electromagnetic spectrum that is still not greatly utilized.
In fact the technology transfers thousands of streams of
data simultaneously, in parallel, in higher speeds with the help of special
modulation, using a unique signal processing technology.
Some Points of LiFi
The light used to transmit the data is called D-light by
Harald Hass,the inventor of LiFi.
In future data for
laptops, Smartphone's, and tablets can be transmitted through the light in a
room by using LiFi.
Security would be a snap—if you can’t see the light, you
can’t access the data.
Applications of LiFi:
Can be used in the places where it is difficult to lay the
optical fiber like hospitals. In operation theatre LiFi can be used for modern
medical instruments.
In traffic signals
LiFi can be used which will communicate with the LED lights of the cars and
accident numbers can be decreased.
Thousand and millions
of street lamps can be transferred to LiFi lamps to transfer data.
In aircraft LiFi can be used for data transmission.
It can be used in petroleum or chemical plants where other
transmission or frequencies could be hazardous.
Conclusion
The possibilities are numerous and can be explored further.
If his technology can be put into practical use, every bulb can be used
something like a Wi-Fi hotspot to transmit wireless data.
