What Is Li-Fi And How Does It Work: Another High Tech Feature For Concern?

The following excerpt is from an article that originally appeared on Natural Blaze

Li-Fi is the acronym for “Light Fidelity.” It’s another wireless communication system running at very high speeds but based in light, not microwaves.

Li-Fi uses LED (light emitting diodes) light bulbs to enable data transfer, another aspect of the surveillance world we live in? Li-Fi uses up to 224 gigabits per second, in essence using light bulbs as wireless routers.

According to Tech World From IDG

An LED lightbulb is a semi-conductor light source meaning that the constant current of electricity supplied to an LED lightbulb can be dipped and dimmed, up and down at extremely high speeds, without being visible to the human eye.

For example, data is fed into an LED light bulb (with signal processing technology), it then sends data (embedded in its beam) at rapid speeds to the photo-detector (photodiode).

The tiny changes in the rapid dimming of LED bulbs is
