What is Li-Fi ?
LI-FI is transmission of data through illumination.
History
This brilliant idea was first showcased by Harald Haas ,From University of Edinburgh, UK, in his TED Global talks on VLC .
How it works ?
“Very simple, if the LED is on, you transmit a digital 1, if it is off you transmit a 0. The LEDs can be switched on and off very quickly, which gives nice opportunities for transmitting data.”
AdvantagesHarmlessnessData transfer rate is highAvailabilityHigh securityEasy to use Low cost
DisadvantagesLight is essential.Light can’t pass through object.
Applications
In traffic signals.In aircraft.It can be used in chemical or petroleum
plants. It can be used in hospitals.
Future scopeIt needs to transfer data in one sight.It needs to transfer data back to transferer.
ConclusionPossibilities are numerous and can be
explored further . If this technology can be put in practical use,every bulb can be used something like a Wi-Fi hotspot to transmit wireless data.
Any Questions…?
Thank You..
