- Li-Fi or light Fidelity refers to visible light communication system using light as a medium for communication.
Light has more capacity in terms of bandwidth in visible light region, therefore it will not disturb in other modes of communication which uses radio frequency.
The triplet Li-Fi technology is introduced with light multiplexing scheme in which RGB color lights are used.
The RGB light combined to form white light which improves the security and capacity.
Triplet Li-Fi is able to carry three data at a time so it will be three times faster than a normal Li-Fi which means three hundred times faster than a Wi-Fi.
The concept of triplet Li-Fi is data communication on fast flickering of light cannot identify by the human eye but it is focused on a triplet photo-detectors which converts the lights into data.
This technology can replace current near field communication system as well as Wi-Fi routers and it will bring greener, safer and cheaper future of communication.
Shibin George lives Kerala, he is an M.Tech. VLSI student at TJIT, Bangalore.
He is a person who is positive about every aspect of life. He is inspired by steve Jobs and loves exploring. His Li-Fi Project has been appreciated at many events and competitions.
This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at ted.com/tedx
it's hard to understand his english but it is a good topic and everyone should watch to know about Li-Fi
hi shibin george... great work..I am very interesting in this work.. How you multiplexing these three light signal.. ?
Using conventional RGB mixing. Red-green-blue lights flick faster these will result a white light as visible. With precision filtering receiver can recover the data.
@@shibingeorge41 can u give your email id
is any special multiplexer or demultiplexer is required for light?
ARUL TEEN It is intended to send data in parallel. RGB can send 3 bit at a time. Flickering rate will be faster than humans perception. Result will be a cool white light that I mean multiplexing.
@@shibingeorge41 you mean rgb led to transmit the three data at a time..am I right? If then how u can receive the individual data? R u using any special filter for that?
would like to use Li-Fi for who I use to get a data connection and how to get it for life What do I need to do in order to use LIFE? Can you help me please
The question can li fi be provided at Ballparks and stadiums? Like how wifi is now?
rf11404 Yes it is possible. LiFi receiver can distinguish sunlight and LiFi. LiFi has it’s own benefit in it’s area like greater speed and security. We are working hard to make LiFi to work seamlessly.
