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 [sic] then converted by the ‘receiver’ into electrical signal.
The signal is then converted back into a binary data stream that we would recognise as web, video and audio applications that run on internet enables [sic] devices.
There seems to be hopeful predictions Li-Fi can make a huge impact on the Internet of Things (IoT).
Since I was not permitted to download the informative video appearing in the very first segment of this webpage, may I suggest you access that video for an enlightening discussion of how Li-Fi works as told by Christina Mercer, assistant editor at Tech World UK.
