One way wireless communication similar to the WiFi burst forth with great force in our daily life much sooner than some think. Instead of radio waves, the Li-Fi uses pulses of intermittent and imperceptible to the human eye, which allow to transmit a larger amount of information and more efficiently, according review aldeaviral.com
Li-Fi technology, which uses visible light from 400 to 800 terahertz (THz), transmits messages via binary code. Thus, it has come to achieve in the laboratory a rate of 224 GB per second, equivalent to eighteen films downloaded 1.5GB at that time.
The term Li-Fi was coined in 2011 Harald Haas, Professor of Engineering at the University of Edinburgh and one of the biggest drivers of this new form of connection using LED lights high power in the near ultraviolet spectrum. The light pulses that last nanoseconds and transmit data through modulators to suit any LED bulb, make them in addition to light, can act as a router for our devices.
