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.
