5.  What is Li-fi ?
Li-fi stands for ‘Light Fedility’ .
Data travel through LED lights.

6.  Harald Hass :The
Brain Behind Li-fi
“Li-fi depends upon the
Intensity & Potential of
LED”

7.  Main Reason for Evolvement inTechnology
To Achieve Error Free, Fast Data Transmission Technology

8. Mobile Connectivity
Health
Under water communication

9.  Wi-fi is great for general wireless coverage
while Li-fi is ideal for high density coverage
in a confined region.
 It is believed that the technology can yield
a speed more than 10 Gbps, allowing a HD
film to be downloaded within 30 seconds.

10.  The light waves cannot penetrate walls.
 it was detectable up to a distance of 10 meter.
 It is similar to the Wi-fi except that it uses
Light waves instead of Radio waves.

11. With the Help Diodes.
