Li-Fi (Light Fidelity) is using visible light instead of radio waves for communication. This new wireless technology can save a large amount of electricity by transmitting data through the light bulbs. In an age where the authors face a challenge of data congestion in the free air medium, where they strive hard to squeeze in all the data in the allocated spectrum. Something they generally use every day, there is not any area where they do not use light. With this emerging technology they can use all the light around they that they produce to transmit data.
