Li-Fi (Light Fidelity) may replace the present Wi-Fi technology in future. Studies have been carried out to improve present Wi-Fi(Wireless Fidelity) technology in transferring data between devices, one of the source from Latest Technology Trends.
Wi-Fi is local area wireless communication, where data transfers through radio waves using 2.4 GHertz and 5 Ghertz.
But Li-Fi is a wireless technology which transmits data using visual light communication (uses common household LED– semi conductor light source which functions as up and down or dipped and dimmed variations at high speed )likely to be 224 Gigabits per second, quite 100 times faster than current Wi-Fi speeds.
Li-Fi was invented by Harald Haas from University of Edinburgh, Scotland back in 2011 and tested that it has capability of downloading 18 movies of 1.5 GB data per second.
The working mechanism of Li-Fi includes, receiving light signals via photo-detector and converted into ‘stream-able‘ content through a signal processing element.
Some of the industries have started using Li-Fi and others have limitations in usage, as Li-Fi cannot be pass through walls and already installed Wi-Fi connections may get interrupted.
Studies have been carried out with better implementation of Li-Fi for major devices in the near future.
