Using Light to wirelessly send data !! Light fidelity !! Apple experimenting with LI-FI

Many researches are being done to use lighting as a source to transmit data wirelessly.

The most basic and common understanding of the above will be our traffic lights. Depending on the lighted colours and whether it is flashing or not, it provides information to users. Of course that is because we have learnt and pre-define the lighting presentation.

Fast forward to 2016, we are actively exploring how LED lightings are able to transmit signals to a receiver where it had been programmed to understand the language of lights. With it, tremendous amount of costs in infrastructure can be saved.

LED Lightings being a point source focus pulse lighting with standardise frequency in its operations (specific models) allow communicate to be made simpler. It is also possible to achieve high speed transfer of data packages.

I've come across a recent report that Apple is experimenting with this technology in its products. In time to come, this will surely be the next break through in the lighting industry.

Imagine with just normal daylight  (CCT: 6000K) light bulbs and we can enhance the wireless network in your homes, offices and living spaces. Not only will internet linked security systems be enhanced, gamers and end users will also not be frustrated with inconsistent network signal strength.

  1. I have read many blogs in the net but have never come across such a well written blog. Good work keep it up
