In this technology, light is passed through transmission channel as it is the fastest medium. It overcomes the defect of WI-FI as well. Transmission of data takes place through illumination. Using this, we can connect to several devices under a single LED light.
GI-FI (Gigabit Fidelity) or Giga bit wireless refers to wireless communication at a data rate of more than one billion bits (gigabits) per second. GI-FI offers some advantages over WI-FI, a similar wireless technology. In that it offers faster information rate in GBPS, less power consumption and low cost for short range transmission as compare to current technology. GI-FI consists of a chip which has facility to deliver short-range multi gigabit data transfer in a local environment and compared to other technologies in the market it is ten times faster. GI-FI has the data transfer speed up to 5 GBPS within a short-range of 10 metres. It operates in 60 GHZ frequency band. GI-FI is developed on an integrated wireless transceiver chip. It has both transmitter and receiver, integrated on a single chip which is fabricated using the CMOS (complementary metal oxide semiconductor) process and it also consists of a small antenna. GI-FI allows transferring large videos, audio files, data files etc. within few seconds.
Li-Fi is the term some have used to label the fast and cheap wireless-communication system, which is the optical version of Wi-Fi. The term was first used in this context by Harald Haas in his TED Global talk on Visible Light Communication(VLC). The technology was demonstrated at the 2012 Consumer Electronics Show in Las Vegas using a pair of Casio smartphones to exchange data using light of varying intensity given off from their screens, detectable at a distance of up to ten meters.

The intersection of railway track and the road at the same level is referred to as a level crossing. In the urban areas the level crossing is generally monitored by qualified railway personnel who monitor the train movement and close the level crossing gate to stop the interfering road traffic but such closing of gates leads to congestion in road traffic and also causes loss of time to road users. Road under bridge and road over the bridge are considered as solutions for avoiding level crossings of roads and railway track.

Li-Fi Technology PPT
1.
2. Introduction
LiFi is a wireless optical networking technology that uses light-emitting diodes
(LEDs) for data transmission.
LiFi is designed to use LED light bulbs similar to those currently in use in many
energy-conscious homes and offices.
However, LiFi bulbs are outfitted with a chip that modulates the light
imperceptibly for optical data transmission.
LiFi data is transmitted by the LED bulbs and received by photoreceptors.
3. History
• Professor Harald Haas, from the University of Edinburgh
in the UK, is widely recognised as the original founder of
Li-Fi.
• He coined the term Li-Fi and is Chair of Mobile
Communications at the University of Edinburgh and co-
founder of pureLiFi.
• Haas promoted this technology in his 2011 TED Global
talk and helped start a company to market it.
• In October 2011, companies and industry groups formed
the Li-Fi Consortium, to promote high-speed optical
wireless systems.
• The first Li-Fi smartphone prototype was presented at
the Consumer Electronics Show in Las Vegas from
January 7–10 in 2014.
Prof. Harald Haas
8. Working of LI-FI
The LEDs can be switched on and off very quickly which gives nice
opportunity for data transfer in the form of Binary code.
Switching ON an LED is logical ‘1’,switching of an LED is logical ‘0’.
Hence it is possible to encode the data into the LED’s by using a
controller ,we just have to vary at which LED’s flicker depending on the
data we want to encode to give different strings of 0’s and 1’s.
UK researches say that using a micro-LED light bulb they have achieved
a data transmission speed of 10Gbps using LI-FI.

11. Main Components Of
Communication System
A high brightness white LED, Which act as a communication source.
A silicon photodiode which shows good response to visible wavelength
region serving as the receiving element.
Receiving elements
Transmitting elements
16. Advantages
Higher speeds than Wi-Fi.
10000 times the frequency spectrum of radio.
More secure because data cannot be intercepted without a clear line of sight.
Prevents piggybacking.
Eliminates neighboring network interference.
Unimpeded by radio interference.
Does not create interference in sensitive electronics, making it better for use in
environments like hospitals and aircraft.
17. Disadvantages
Light can't pass through objects.
A major challenge facing Li-Fi is how the receiving device will
transmit back to transmitter.
High installation cost of the VLC systems
Interferences from external light sources like sun, light, normal bulbs,
opaque materials .
18. Conclusion
By using Li-Fi in all the lights in and around a building, the technology
could enable greater area of coverage than a single Wi-Fi router.
Drawbacks to the technology include the need for a clear line of sight,
difficulties with mobility and the requirement that lights stay on for
operation.
