Day by day activities is to send data

Day by day
activities is to  send data one
destination to other destination.
 Li-Fi technology has another benefits over Wi-Fi, for example safer for
nuclear energy-producing station, thermal energy-producing
station in that places Wi-Fi are not used.1.Some energy-producing station in which  RF
wave,s is injurious and it may reason of disaster.The
way of communication in such stations only visible light spectrum can be
used.There are four working methods of 
Li-Fi and Wi-Fi are, Efficieny,availability,capcity and security  Wifi and Lifi technology both uses the electromagnetic
spectrum for communication ,but WI-FI uses radio wave,s spectrum.2.(The
present wireless networks that linked us internet. Working  slow when linked  many devices. As the number of devices
increases then internet speed goes slow. available bandwidth  makes more and more difficult to enjoy high
data transfer rates for  a secure
network. As radio
waves are just a small part of spectrum.This problems Solution  is  Lifi technology. Li-Fi is  data transmission through  by taking  fiber beyond fiber optics by Transferring data
through  LED light bulb 3 This
technique make data transferring as faster as compare to human
eye can follow.

 Li-Fi is the term  of fast, cheap wireless transmission system,
which is advanced  type of Wi-Fi. Li-Fi
using observable light inspect  of
Gigahertz radio wave,s for data transference.  3. This idea of Li-Fi was proposed by German
scientist , Harald Hass, in which he concluded 
as data over illumination. This knowledge Li-Fi was first used by Haas
on his TED Global talk on Noticeable Light Communication. Rendering to Hass,
the light, which he concluded that the D-Light, it can be used to produce data
rates higher than 10 megabits per second which is more as more  faster than our average broadband connection
4. Li-Fi can relieving the heavy loads which the current wireless systems
face. LIFI offers much larger frequency band (300 THz) compared to that
available in RF communications (300GHz). As more data coming through the
visible light spectrum could concerns that the electromagnetic waves affect our
health. Li-Fi can be new technology  as
for  future where data for
laptop,mobiles  and tablets will be
transmit through the light in a room. Security cannot  be the 
issue because if you cannot see the light, you cannot  access the data. As a result, it can be used
in high security military areas.
