Now a days with the advent of new technologies, the
has become the basis of ICTs. ICT made our globe as
the city. Today all (institutions Businees

Information at the right time and right place. which,

Link (LI-FI) that can affect all life. It's
the technology that can be as fast as in 30GBPS (500MBPS
minutes) an alternative, cost-effective and more reliable and
more useful than Wi-Fi. visible light communication
Maybe the future of the Internet

INTRODUCTION
The Internet service is very very high and
Necessary accessories in the field of ICT. In accordance with the Cisco survey
use the existing spectrum, we currently
using about 80 percent of the existing possibilities of data
the use of. Currently we use Wi-Fi services
on campus and around 10-100 meters distance
to connect our P.C. 's, laptops, palmtops and P.C. Notes, etc.
This work includes visible light communication
that can provide a wide and high speed data transfer, as
the 500Mbps. a study on the comparison between
WI-Fi and LI-Fi. And other important parameters
the communication process.
LITERATURE REVIEW AND
The Acceptability Of The Li-Fi
This was in July, 2011, Dr. Gerald Hass, Professor, mobile
communications, University of Edinburgh, publicly
demonstrated loyalty to light for the first time, how to
Visible light communications (VLC) technology further.
Researchers at the Heinrich Hertz Institute in Berlin,
Germany achieved a data transfer rate of over 500 Mbps using
standard white light LEDs. Dr. Gerald Hass also has settings
a spin-off company to sell the VLC transmitter.Even more
sophisticated and advanced techniques are
development at the University of Oxford and
The University of Edinburgh. The team from the University of Oxford
and the University of Edinburgh focused on parallel data
transmission using led arrays, where each led
transfers to another data stream, whereas other groups
a mixture of red, green, and blue LEDs to change light
The frequency of each frequency data transmission channel coding.
Today researchers are working for its feasibility and
design of hardware equipment required to perform
The technology is reliable and useful.
Li-FI-technology has a higher potential, it is very
You can transfer data via light by changing the
flicker rate, provide a variety of line 1 and 0, and its
The intensity is modulated so fast that the human eye
may be negligible. There are about 19 billion light radiates
Around the world. Which may in turn be replaced by led, i.e.
a potential source of data? "This is based on the
Technology of new generation high-brightness LED
light-emitting diodes, "said Gerald Hass, from
University of Edinburgh, United Kingdom is very simple, if the led
you transfer digital 1, if it is off, you pass 0,
"They can be switched on and off very quickly,
gives good opportunities to connect and transfer
Data very quickly, efficiently and accurately without any
external interference.
