Data Transmission Using Visible Light

Light is indispensible part of the life. In the present days, LEDs are becoming the main source of light of lighting in many areas.  Mostly, White LEDs so, can we use them to transmit data? The answer is yes! We use Radio waves as the main sources of transmission these days, but the Radio Frequency (RF) spectrum is limited and they cannot be used in certain places like Hospitals, Underwater, Petrochemical plants or Planes. This technology solves the problem. It is safe to use anywhere, where light is available.
