Today internet has become a fundamental need
of each and every person. People use wired or wireless
networks for accomplishing their tasks. As number of users
get increased wireless network speed decreases
proportionally. Though Wi-Fi gives us speed up-to 150mbps,
it is still insufficient to accommodate number of desired
users. Li-Fi technology which was proposed by the German
physicist— Harald Haas has proved to provide transmission
of data through illumination. The data is sent through an
LED light bulb that alters in intensity faster than the human
eye can follow. This paper focuses on developing a Li-Fi
based system and evaluate its performance with respect to
existing technology.

The future holds the unrevealed answer as the possibilities
are huge and if this technology is brought into practice
every light emitting devices would be like a Wi-Fi device
and transmitting signals, this will lead towards a better,
safer, cleaner and greener world. This concept allure a
great deals of research as increasing number of devices are
using the Wi-Fi, airwaves are said to be encumbered
making it difficult to be reliable high speed data
transmitting signal. This will immensely solve the problem
and allow internet to places where traditional wireless
signals are banned such as aircraft. The transmission cost
is low with high speed of data transfer which increases the
speed of communication with reliable way.
