Li-Fi, or 'light fidelity', is a technology that transmits data using LED lights, achieving speeds over 10 Gbps. It is suitable for high-density coverage in confined spaces, unlike Wi-Fi, which provides broader wireless coverage. The technology presents applications in mobile connectivity, underwater communication, and error-free data transmission; however, light waves do not penetrate walls.

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

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.
