This book has come up with a solution of "Data through Illumination" - Light Fidelity known as Li-Fi which takes the fiber out of fiber optics by sending data through an LED light bulb that varies in intensity faster than the human eye can follow. Li-Fi is a VLC, visible light communication, which uses visible light on electromagnetic spectrum for communication. Li-Fi is part of the Visible Light Communications in PAN IEEE 802.15.7 standard. Li-Fi is typically implemented using white LED light bulbs. These devices are normally used for illumination by applying a constant current through the LE...
This book has come up with a solution of "Data through Illumination" - Light Fidelity known as Li-Fi which takes the fiber out of fiber optics by sending data through an LED light bulb that varies in intensity faster than the human eye can follow. Li-Fi is a VLC, visible light communication, which uses visible light on electromagnetic spectrum for communication. Li-Fi is part of the Visible Light Communications in PAN IEEE 802.15.7 standard. Li-Fi is typically implemented using white LED light bulbs. These devices are normally used for illumination by applying a constant current through the LED. However, by fast and subtle variations of the current, the optical output can be made to vary at extremely high speeds. Unseen by the human eye, this variation is used to carry high-speed data. In our project we are transmitting the audio signal based on visible light communication using LED light bulbs as the medium. We hope that this project leads to an alternative for the use of radio waves in communication purposes.
